SIG P365 Grayguns Flat Trigger Installation

Complete SIG Sauer P365 installation and reassembly for the Grayguns flat trigger.

[@keithwray9942]

Thank you for the video! It gave me the confidence to try this myself. I had already installed a flat trigger on my P320, but this one was a little more challenging and your vid helped a lot.

[@jayinsley47]

Thanks for posting this, I followed it step by step - minus pulling the one pin out to far!

[@EricCouture315]

Excellent. Just watched your video twice. The second time I did the steps with you. I didn't lose the lifter so that was a plus. But this video was perfect! Thanks!

[@michaelk5173]

Excellent video! While it’s the first I watched on trigger replacement, it was detailed, and clearly explained.... not rushed either. Great job!👍

[@MarkSangamon]

I've been trying to get this thing back together most of last night. This morning after watching your video, I got it back together in about 5 minutes! Thanks!

[@mathew6288]

I NEVER would have had the guys to try this until watching your video. Step by step and worked flawlessly. Thank you!!

[@mattwessing850]

Thank you! Your video was very informative and helpful. Got mine installed in about 20 minutes. Much more involved than the P320 trigger install but easily done with proper tools and some mechanical experience.

[@patrickisrael2342]

Great video! Thank you. Short (as it could be) and to the point with simple explanations. I’m no gunsmith and this was easy thanks to your guidance.

[@robertpfaff8779]

My first time since Basic Training that I have field stripped a firearm. Installing a Sig Sauer brand flat trigger was made easy thanks to this video. Had a couple minor issues along the way, but I just backed the video up and tried again. Thanks!!!

[@billy45acp]

I don't have a p365 as of yet but love watching videos like this. Just wanted to say that was a excellent video.

[@scottwaleck6304]

Great job and so nice to see a slow and clear description! Thank you!

[@Timrh23]

Thanks for posting. Tiny parts and amazing engineering by Sig. There certainly were teething issues w this piece but it is an engineering marvel.

[@stopthephilosophicalzombie9017]

I agree. I hope that more gunmakers go the modular route. I'd especially like to see a modular version of the PPQ, but judging how they did the SC, I'm doubting Umarex will foot the bill on R&D.

[@AlmaCole]

Agreed. It's great to see the designs evolve.

[@ryanmiller8459]

Not really.. try working on a chronograph automatic watch.

[@JK-vc5vu]

Is Sig addressing the striker drag issue with these?

[@BloodySoup74]

@@JK-vc5vu Probably not. They can only do so much in a package like these. They'll just fix with the same parts they have under warranty. Some other small guns have primer drag too. I went ahead anyway and bought the 365 last Friday. If these strikers were breaking with under 500 rounds through them then I would not have bought one. I'm seeing them break around 2000-3000 rounds. Just remember small pistols are not meant for 10,000 plus rounds anyway like duty pistols. I'll replace parts at 2,000 rounds just for the hell of it.

[@johncashwell1024]

Thank you Mr. Cole! Just installed my new trigger pin, spring and flat trigger (Kit-365-FLAT-TRIGGER) from Sig Sauer. Just went slow and easy, step by step and I am very pleased with the outcome. One thing to note is that my P365 is a newer version and that piece you slid out, too far, is nitrided with a slightly different profile but otherwise all steps are the same. Thank you!

[@nathanmindblog]

I changed my P365 w/ safety today and it took 10min. Your video helped a lot! I even took it apart and put it back together again just for kicks. Big THANKS!

[@RoadTraveler]

Watched a few of these videos yesterday, but I found yours the most helpful. Thank you for this excellent tutorial!

[@RobertLarsen2111]

Man, thanks for uploading this. I did one search and this video came right up. Nice to see good lighting and a clear view of whats going on. So many videos seem like they were recorded in a basement with a potato. Awesome work boss and thanks again

[@Liquorfellers]

Thank you for the video! You broke it down better than any other video. I was able to keep the safety striker lifter in place and no other video I saw had shown that was possible.

[@peptors6686]

Fantastic job, great detail and explanation. Was able to do it without major challenges. Thank You!

[@jonk4462]

Thanks for posting this instructional video. It was easy to follow and I used it to install my Sig brand flat trigger.

[@johnbaratta3259]

I was just going to go for it. This video is PERFECT. I'm ordering the trigger now.

[@JPHoka76]

Thanks for posting this. Watched it twice, installed mine in 20. Thanks again.

[@SniperFire45]

I had a bit of trouble with mine getting the take down lever in place. I had to remove the trigger and then put the take down lever in, in order for it to be flush. I was contacting the trigger bar slightly. All good now. Thanks for your video. It was very helpful.

[@gataxis7737]

Thank you, I got mine installed in about 30 minutes, I am a newbish when it comes to gun smithing but this wasnt too hard of a job. Video helped a lot.

[@Josh-jg2hi]

Thank you so much! I would NOT have figured this process out without videos like yours!

[@AlmaCole]

Glad it helped

[@randominternetprofile8270]

Thanks for the video. It was so detailed during disassembly that I reassembled it before you did 😆 I already have the xl and wanted the micro, so ordered the sig flatty to keep my pull consistent.

[@randominternetprofile8270]

But seriously, who downvotes this? People that made bad installation videos?

[@gvmoeller]

Again - great video for people looking to learn (like me). The only benefit I can see (other than a switch from curved to flat trigger) from this upgrade is the ability to adjust (reduce) the trigger over-travel. The stock trigger has a solid "nub" that acts as an over-travel stop (maybe it is cast in?). It is static and the only modification is filing it down, which would increase over-travel.

[@papalilburn]

Outstanding "how to" video! Camera work was clear, great lighting and audio!

[@Filmpilot]

Awesome. Thank you for the detailed, yet succinct explanation!

[@rjoshm20]

Great tutorial, flat trigger installed with no issues. Now to the range!

[@johngaltfan9703]

Followed your video and advice step-by-step (including the safety striker lifter) and installation was a snap. thanks for producing this!

[@AlmaCole]

Great to hear!

[@marksd5650]

Now that I just installed the Grayguns adjustable trigger, I watched your video again and realized how I could have made my life easier because I dropped the lifter out, and I put that lifter back last. Yup, last. And my reassembly was complicated by a manual thumb safety (I’m in MA). So, I guess now when I do my wife’s it will be easier, or maybe I can not pull the pin as far out.

[@nathanmindblog]

If you have a manual safety then the lifter will never fall out. You lift that silver rod (mine is black) it hits the bottom of the safety and stops. No way to pull it out more to make the lifter fall

[@christopherstromberg3070]

Thanks for the video. Made this job about 10 minutes. Really appreciate it.

[@robertseelig5973]

Thanks for the video brother! Super helpful, was able to install my flat trigger no issue👌🏻

[@johnmixtacki2879]

Thank you very much! Great instructions! Took about 20-minutes!

[@billfrenette]

I have taken my P365 apart many times, and never once did i need a hammer, I have changed the sear spring , the striker spring, the safety spring and rreduced the trigger pull from 6 lbs to 4.2 lbs. I thought this video was about reducung the pre-travel. My fault read the description wrong. I think I will start putting how to videos out, I am not any where as good as the Sig Guy, better than what I just watched. I did learn some things from this video so well worth watching. Thanks for the video

[@larrydunham3022]

Excellent video! Thank you! Easy and straightforward. Well done!

[@josephchandler2302]

This helped me change my trigger on my P365! Awesome video, step by step.

[@Cornetman2000]

Thank you for posting this! made the job very easy and simple.

[@williamjkoch]

Thanks for making this! Watching your video, I was able to successfully install my flat trigger.

[@mikem2132]

This video was very well made, helped quite a bit with my installation. Thanks!!

[@SFJF26]

Thanks for this!! I just installed the flat trigger that Sig sells (not the grayguns) but it went in exactly the same. Great video thanks again!

[@Reece634]

was it worth the big bucks? what do u think about it

[@SFJF26]

@@Reece634 the Sig trigger was half the price of the grayguns and I doubt you would notice the difference. I like the flat trigger better than the curved trigger.

[@yurikovalev627]

Excellent video !!!!!!... thank you for posting this. You made the switch very easy !!!!!!!..I highly recommend this video if you are thinking of putting in the flat trigger....

[@apeshitcrazyman]

Super helpful! Thanks bud, you da man! I could not figure out that disconnector until you helped! Thanks

[@be4283]

There were a couple things that were different on my P365 so it kinda freaked me out but everything seems to have turned out fine. Great video!

[@huntercates5895]

Super helpful, thanks for the instruction. I was able to do it pretty easily with your video

[@fishnhunt3488]

Brilliant video! Followed along and piece of cake!! Thank you, sir!

[@jkhomerepair]

Good video brother... your video helped me install my trigger which was still a little frustrating but got'r done! Thx.

[@scorpio0281]

Thank you so much for the video. Was playing 9 kinds of hell trying to get the take down/slide lock bar and lever back in. Couldn't remember how I got it out lol! Soon as you said bow it from the middle, dropped right back in place.

[@Dirtbag-dy4nx]

Awesome video, Thank you for sharing.

[@davidmette6089]

You did it the hard way for sure.. You don't have to mess with the "silver pin" and parts falling out when you do..

[@michaelballard3699]

Hey thanks for the help! Got my trigger installed and working!

[@Scott-Heil-11]

Thanks for posting. Great video

Great video. Very helpful on my first install. Thanks.

You're the man Alma... Saved my bacon.. Thanks

[@papo2132able]

Great video got my flat trigger installed.

[@UnicyclistRTB]

thanks bud. Clean tutorial and nice step by step. i made the mistake of not landing the trigger spring in its "body hole" ( for lack of better terminology) the first time as i thought it landed on the ridge of the hole but that was due to poor lighting and not your video. thank you for the help my friend.

[@jeffsweeten3270]

I am DEFINITELY not a gunsmith but I managed it... VERY informative and it'll have purpose for as long as the P365 exists!

[@robsegrin764]

You made putting that trigger bar spring a LOT easier than it looks

[@AlmaCole]

It's hit and miss for me too

Very helpful video. Thank you for posting!

[@edgarvega6906]

Very well done video. Thanks for posting

[@Username-ld7ho]

Great video. Followed step by step. It did probably take me 30 to 45 minutes tho. I couldn't get the slide on after I finish, and then I noticed that the bar on the left side wasn't in the right position. So I had to take it apart again and make sure that the rear of the bar was all the way back. It works now tho. I just need to get the 12 rd base plate. I had the 12 rd mags and they didn't come with that plate for some reason. I will probably get those magnuts base plates, springs and followers. I also wanted to change the frame for the xl one, so that's why I need those plates

[@rodneywilliams4548]

Seems easy enough for a novice like myself. Thanks Mr Cole

[@AlmaCole]

It's not bad. Take it slow and one step at a time and you'll be fine.

[@jollyranchhand]

Thanks for taking the time to post this. I did find that catch release lever isn't very mechanically stable without the grip housing there to help support it. Its difficult to know if you really have it right or not because it feels wrong even when it's right.

[@meganfox4671]

Thank you for posting such a clear video on how to do this. Made the same mistake you did lol but all turned out well

[@tomcat207]

Tnks! Worked perfectly according to your instructions!

[@mlee2240]

Thanks for the video. I just hoped you would have shown us best feature of the Grayguns flat trigger over the Sigs flat trigger. The adjustment feature of eliminating the over travel. It would help us to determine if it’s worth paying more than double for it. Keep up the good work!

[@roswellianfuture6778]

Just installed mine in my 365xl and I can tell you it certainly is worth it. Makes the trigger reset shorter too.

[@jameslogan6127]

Well good video very informative and I learned a lot. Mainly I learned that I’m not ready skill wise to change to a flat trigger. Still very cool video.

[@mikeheckman4995]

Thanks man. I’m not a gun smith by any stretch, but stumble through most things with a little YT guidance. AAA+++

[@gwithrow79]

Great video, man. I did not have to take the slide release out. But either way, Thanks!

[@TYMWLTL]

Nicely done Thanks

[@malcolmmartin3027]

I just installed this thank you im going to try it out tonight you did a great job explaining this for us gunsmith idiots 👍

[@rustyironrob]

Your video was VERY helpful for installing my new Armory Craft trigger. This is the sort of project where I'd just jump right in, but it would have been FAR more difficult and stressful had you not provided the proper steps.

[@helterskelter416]

excellent video, 10/10

[@CDCLLC]

Thank you for this video! Immense help!

[@mikemurphy7516]

Very helpful video: I don't think I would have managed it without the video, and had some false starts even with it. BTW: I did weigh the triggers, and although I didn't go to fractional grams, the factory trigger and the Gray Guns flat trigger both weighed 7 grams on a digital scale.

[@mikemurphy7516]

I also tested the trigger pull before and after installation with a Wheeler Engineering digital trigger pull gauge. With a trial of 20 pulls before and after, the difference in mean pull was a 3 ounces with the samples having standard deviations of 4.4 and 5.4 ounces, meaning that there is a statistical difference (p=0.5) but no practical (perceptible) difference in trigger pull weight.

[@kevinsun3284]

Very helpful, thank you very much for sharing!

[@Subtlenimbus]

Great video. The part you refer to as the Striker is actually the Sear. The striker is in the slide.

[@Trappersdead]

Very helpful, thanks. Question: my trigger bar spring has an extra bend in one leg. Did I accidentally cause this during removal or is normal for newer build dates (sept27)?

[@shabbatman370]

I am going to give it a try

[@GruncleWorx]

Appreciate the video, allowed me to install a Sig Flat trigger with minimal of fuss! Awesome work and a great help! ;o)

Thank you!

thank u great vid. seriously.

[@mrwashur1991]

Just a tip, buy Lucas marine grease instead of their gun grease. If you look at the safety data sheet on the two, they are both identical in make up and amounts. Only difference is that the gun grease has scent added. A tube a marine grease is like $5-$8 for 14oz instead of .5oz for the same price. Lucas is known to add higher prices just for the labeling of their items. Their gun cleaner and contact cleaner are both exactly the same with the only difference is one is $3 and the other is $8. Just saying you can save tons of money just for a different label.

[@austinicholas]

I found that when I take it down if I push the slide elease forward after dropping it and slightly pull/push back before sliding forward it slides right off without resistance.

[@sunnycat69]

My gf oem flat trigger just came in today thanks for the video 🇺🇲 how do you guys like running a flatty ?

[@d-unit-outdoors]

Thank you!!!!!!!!! Thank you thank you!!!

[@peterd866]

By watching the video two or three times then following along I was able to install my Grayguns Flat Trigger with over travel adjustment without any issues. The instructions and camera angles were very good. I would like to note that I purchased my 365 in November of 2021 and some of the parts were updated and not the same shape/color as the ones in your pistol/video. However the instructions still worked and I didn't have any issue. I will add that it took a bit more force to get my take down lever back into place then yours did, but nothing a little elbow grease didn't take care. Overall great video and still relevant to the newer 365s coming on the block in 21/22!

[@gvmoeller]

Great video! Can you share a bit more about trigger pull length, reset, etc? I am considering this upgrade, but your video does not discuss the real-world improvements that result. Thanks.

[@andygonzaga4337]

Can you do a video with the P365 with thumb safety flat trigger installation or is just the same

[@georgeweber1337]

very helpful.

[@JoeyLocig]

After completing my swap the fire arm does not fire. As if the safety is on. If racked while holding trigger a can hear a rest when let go. If I hold the trigger while slowly racking back it sounds like a hammer might have dropped... Any ideas??

[@dinospumoni8860]

I just picked up my 365 today and it doesn’t have that silver pin thing on the side. I guess sig redesigned it cuz the pin is black now, way smaller that the silver one and I was able to pop the bar out without even pulling the pin out.

[@80ninevision]

It's almost easier to take that safety level out. Just finished mine. I had a hard time with the slide disassembly level. I just backed out the safety level pin put more and I was able to align everything perfectly.

[@Pippinm7]

Is this the same flat trigger they have in the Sig P226 SAO?great video!
