Sig MPX Review Part 1 Ep 1509

[@Lmm150]

Excellent detail and video quality. Most detailed MPX teardown available. Looking forward to parts 2 and 3.

[@EnduringEagle]

This was nothing short of Outstanding! Format was terrific, wonderfully shot, fantastic information and your on screen demeanor is nothing short of inviting and professional. Well Done!

[@Learningfirearms]

EnduringEagle WOW, what a compliment, thank you so much!

[@jgefaell]

@@Learningfirearms ^^^^ He's right you know. Top rate. Thank you sir.

[@josephcarioggia9506]

Spot on. What a pro!

[@shootinbruin3614]

By far this is the most detailed video on the MPX I’ve ever seen. The intro didn’t hurt either haha

[@LowLevel157]

This is a fantastic review. Just wow. I wish everyone reviewed guns the way you do. Well done!!!

[@Learningfirearms]

Thanks. Check out the new channel Guns & Tactics

[@WhiskyTangoFoxtrot33]

Best MPX vid I've seen yet. Keep up the good work.

[@Learningfirearms]

Thank you! Glad you enjoyed it. More parts coming soon

[@MrGunman11]

WhiskyTangoFoxtrot33 Agreed!

[@czechtactical8388]

Best technical review of the mpx that I have seen.

[@Learningfirearms]

thanks

[@zackwiemer5788]

Hands down, best intro on the Internet. Awesome review. Looking forward to watching the rest. Thanks!

[@Learningfirearms]

+Zack Wiemer thanks, glad you liked it!

[@fredboat]

Just ran across the video, Enjoyed it, I bought a Sig MPX 9mm pistol in 2015 and SBRd it , I added an ambi charging handle in 2019 and an upgrade trigger pack. As a lefty I like the ambi controls .I have had No problems with it. Shoots fine. Later from Texas.

[@scottsmith6330]

Now that was an amazing video. I have seen other MPX videos that just gloss over the mechanics of the pistol. I plan to get one and this will be my go too vid for taking it apart. Good job guys.

[@Learningfirearms]

Scott Smith Really glad you found this useful, thank you for the complement, we hope this will be a tool everyone can use for years to come! -Trevor

[@funtohave5604]

Empressive video, truly elaborate step by step take down

[@jonfrauen3779]

Great explanation of the breakdown of the weapon. Nice job and very informative.

[@Boombox666]

You went full on bro! Thank you for the breakdown, very in depth, although I'll have to watch it again because i had a few beers when i watched? But definitely very comprehensive and I'll have to watch again, just got my sig mpx and haven't put any lead through it yet

[@Learningfirearms]

Thanks!

[@turborsx5740]

Thanks for the video, yeah you're the first one I've seen did a complete tear down & identifying parts. Nice vid!

[@Learningfirearms]

Thanks!

[@Learningfirearms]

Thanks

[@garretthart13]

Thank you so much for this video, i have been looking for decent pictures of the gas system for weeks before i bought one

[@Learningfirearms]

+Garrett Hart glad you enjoyed it. Thanks for watching

[@ava9oh1282000]

great video Tim, looking forward to the series and the future video on the channel...

[@Learningfirearms]

Thanks! Part 2 is in editing now, coming soon.

[@josephcarioggia9506]

Timeless video. I've only had mine about a year. Idk about breaking it down that far though. Might need a professional for it.

[@shotover7719]

Best video on the MPX to date that Ive seen! Im back and forth on the MPX or the HK SP5K. I have a dealer who handles both and will sell me either one but he definitively prefers the SIG MPX over HK SP5K for a host of reasons like fit and finish and over all cost. Thanks for a great review!

[@Learningfirearms]

Thank you very much!

[@douglilesbusdev]

This video is essential for anyone wanting to lean how to disassemble an MPX. Recommend editing out the intro. You'll get more traffic that way.

[@Learningfirearms]

It made us laugh. It people don’t like it I don’t care ;-).

[@currentdomain8421]

Thank you Dave for such a high quality content of this video. I appreciate "the review in parts", it was immensely helpful in taking my mxp apart for cleaning. I only wished you had taken this review a bit further. Namely, I would have loved to see the disassembly and reassembly of the trigger group. Could you please make another detail (very stable and closeup shots) of you taking out, and apart the trigger group, and its subsequent reassembly. An eagerly awaiting patron. Cheers brother! :)

[@Learningfirearms]

+Current Domain Hi there, thanks for the kind words. Hopefully we will finish the series later this year. Finances and federal wait times haven't helped. Removing the fire control group is actually just like an AR with two exceptions. 1 is the roll pin on the ambi safety that we pointed out. 2 is the trigger bridge. We have a video on removing an AR fire control group that would explain exactly what you're looking for. Thanks, Dave

[@craigsullivan538]

Excellent break down. I just got my MPX cant wait to tear into it.

[@Learningfirearms]

Craig Sullivan I think you will really enjoy it!

[@NOIRAAG]

I wasn't a big fan of this gun before. It looks cool but it just wasn't impressing me. Now I'm a fan. Great video. This thing is an awesome piece.

[@Ducky27645]

Great vid guys. Just bought mine today!

[@Learningfirearms]

Ducky27645 congratulations!

[@bootchumbley2381]

Very well done. It is sad to see that sig never came through with the multiple calibers

[@rustybarber]

Subscribed, best review so far.

[@Learningfirearms]

Thank you!

[@ragingbullwinkle4188]

Great video really helped thanks. Just got my MPX this week ;+)

[@Learningfirearms]

Thanks for watching

[@joro3108]

Great tear-down vid. The paint flakes everywhere kill me. I know you will clean them all away before reassembly, but seeing them all over the place hurts my soul. Thanks for the great video. I really wanted to see the operating mechanism.

[@Learningfirearms]

Glad you liked the video. I'll see if we can come up with a better pointer to save your soul :-)

[@joeschmoe2659]

A sexy gun need a sexy intro... great job! This is a great video! I own an MPX v2 8”... I am going to grab a MOX rattler 4” version. Damn I love AMERICA!

[@ragingbullwinkle4188]

oh and I also Subscribed, best review so far.

[@Learningfirearms]

Thank you!

[@IBEYEBALLINU2]

Thanks for the technical detail. Others who are interested might want to know the benefits of a AR type lock up mechanism for a relatively low pressure 9mm pistol round that functions reliably in blowback pistol/carbines formerly used by the military such as Uzi type. I was looking for such a lock up system in pistol calibers for some dynamite reloads I am considering developing in other calibers. Subscribed because of your comprehensive presentation.

[@Learningfirearms]

+BENJAMIN DAVID BENSON Thank you, I can talk more about that in the future

[@ava9oh1282000]

Dave. Part two was great. Only one question... How will you be mounting your suppressor? That thread pitch is very unique... Do you have an adapter? If so where is it from because I need one.

[@Learningfirearms]

Thanks! Part 2 will make its way to KZbin eventually but full30 always gets first shot (pun). I will be using a 3 lug adaptor so I can use MP5 mount suppressors as I have other mp5 platform guns. I have a review in the works for the adaptor which is from Tros USA, 13.5LH to 3 lug.

[@ava9oh1282000]

thank you Dave. much appreciated.

[@matthewslusher8309]

awesome video!

[@Learningfirearms]

Thanks!

[@njw1977]

Great video, Thanks!

[@Learningfirearms]

+njw1977 thank you

[@knighthawk6633]

WARNING - read before you purchase. Test your ILWT barrel to ensure that ammo feeds correctly. Mine did not because of a high feedramp. ILWR is 0.060” compared to the OEM 0.035””. The higher feedramp resulted in bullets nose diving into the base of the feedramp and not onto the feedramp resulting in stoppage. Because I let the gun sit in my safe for a year and did not identify and report earlier, ILWT won’t work the issue and I am required to make Dremel modifications to correct the geometry of the feedramps to allow seamless feeding and function. I highly recommend identifying the issue early and brining it to ILWE’s attention or else you too will have to break out the Dremel.

[@Learningfirearms]

This gun is all factory and doesn’t have an ILWT barrel fyi

[@usmpshaft]

Thanks Brother, I have that pistol, however thinking about making it a SBR so I can make it more me.

[@Learningfirearms]

SBR is the way to go if you really want to get the most out of it. -Trevor.

[@usmpshaft]

+Learning Firearms Right on, I'm going to get the paper work soon, thanks again, Blessings.

[@thomasbednar7475]

Great vid. Thank you.

[@pagodadr]

Best review!

[@MegaFlamingzombie]

5 years later: No caliber changes Less accessories are given. (No case, sling, iron sights) Higher price

[@tedzhou2107]

Hi, I just wonder does the BCG top part and bottom part move at all? Mine have some play, two piece will actually have some movement ...

[@Learningfirearms]

They are two separate pieces. A slight feel of play is normal.

[@bigvisk1125]

anything happening with this series? would love to see you run it suppressed and as an sbr

[@Learningfirearms]

Part two is already out, part three and four are at the mercy of the federal government and sig arms :-)

[@bigvisk1125]

+Learning Firearms I recall part 2. guess I'm just waiting on you waiting on the feds. thanks

[@Average3djoe]

How much?

[@fastr144]

do you know which red dot it comes with?

[@Learningfirearms]

Ours didn't come with a red dot. I think other models come with the Chinese made Sig aim point copy. I personally don't care for Sigs red dots.

[@fastr144]

Learning Firearms I noticed the rattle you mentioned and found that it was the front take down pin area, the upper has a little play and shifts right and left. I ended up cutting some packaging and sliding it between the upper and lower tabs and its a nice fit. I think i'm going to switch it to just a dab of silicone though. awesome video! looking forward to the next one!

[@Learningfirearms]

Regatoni5​​ part two is up on full30.com thanks for letting us know about your experience so far. I will even find our link. www.full30.com/video/8b61314e54266ba1bfd9f2ec04f6e5ea

[@andrewedelman3968]

Is this mpx a gen 1?

[@Learningfirearms]

yes

[@theARMORYchannel]

excellent, SUBBED

[@Learningfirearms]

+theARMORYchannel thanks! you have a great channel too

[@josephcarioggia9506]

Me too just now...

[@leonfdawson]

Sorry but I'm uneducated, but I always thought a pistol was a hand gun? How is this a pistol, I would have thought it was a sub-machine gun. PS How tall are you. I'm 6'5, would this weapon be comfortable for me?

[@Learningfirearms]

Pistol is the federal classification as it doesn't have a stock. A sub machine gun is a full auto gun. This isn't your traditional pistol by any means but there are more like this coming to the market where guys will register them as an SBR and add a stock. I'm 6'0 and one of the other guys is 6'2. It's a fun gun to shoot. As far as comfort tough to say and everyone is different.

[@leonfdawson]

OK, thanks a lot.

[@SteveJenkins]

Great vid! One FYI - Sig has now stated that (even if one fits), you shouldn't swap in another AR trigger group, as it will void the warranty. The issue centers around the trigger bridge. See my blog post at www.stevejenkins.com/blog/2015/06/will-upgrading-the-sig-sauer-mpx-to-an-ar-15-trigger-void-your-warranty/ and my video at kzbin.info/www/bejne/d4fdpmCglpt5f5I for more details.

[@Learningfirearms]

Steve Jenkins Hi there, thanks for watching and the comment! I've been tearing into this issue as I noticed when I first got the gun it had an extra piece, the trigger bridge. It's function is to prevent trigger slap, i.e. movement forward from being hit by the hammer. Some AK triggers frequently have this. Due to the high cyclic rate of the gun they were concerned with trigger slap. I'm working with the Sig tech on ideas, luckily I have an email stating swapping triggers will not void warranty :-) not that I am really worried. It is off though how Sig promoted that compatibility of AR triggers at various shows and events but now says its a no go. I am also going to using a different AR type trigger that has a different hammer design that won't be an issue due to the geometry. Part 2 is coming soon, a little sooner if you're on Full30 :-) Thanks again!

[@SteveJenkins]

Learning Firearms Which trigger group are you considering? I'm thinking a Geissele SSA would be sweet. :)

[@Learningfirearms]

Hiperfire EDT, it has a modified hammer that won't slap the trigger. Right now it's my favorite duty/working gun type trigger. I do really like geisseles too

[@fastr144]

Steve Jenkins I read your paperclip thread on your blog. Thats good info! I did the same and used a thin piece of plastic (packaging) behind the buffer and paperclip and ended up doing a twist in the paperclip to give it a bit more strength. how is your buffer holding up? any abnormal wear yet?

[@SteveJenkins]

Regatoni5 So far, so good. Let my 13 year old daughter shoot the MPX today, and it ran like a champ. :)

[@dugstruble]

That's a lot more complicated than a CZ Scorpion Evo.

[@Learningfirearms]

It appears to be, but it also appears to be the better platform with more modularity. I like the commonality it has with the AR versus with the CZ you are stuck with some of what you get. If you're familiar with the AR this is that complicated at all. No doubt the scorpion is built from a very strong reputation though. Thanks for the comment

[@mattlorenson4266]

This dude lost a lot of weight

[@edmaguire1012]

You should be wearing safety glasses when handling stuff with springs.

[@Learningfirearms]

Ed Maguire I agree you should be

[@grantmacdougall2553]

Is it weird I got a chubby watching the intro???

[@ironmikez2247]

I’m I’m

[@kirjathsepher3275]

Great video! But... this gun frankly isn't worth the asking price and this video convinced me not to buy it. Tolerances are unimpressive. The screw on picatinny rails (personal dislike), non grooved receiver pins that have been reported to walk out during firing and cause malfunction, ugly recoil buffer at the back of the receiver, the shoddy case and single $70 retail magazine, and general fit and finish seem lacking. The quick change barrel is a good idea but will undoubtedly affect accuracy (admittedly negligible at sub gun ranges). Only things its got going for it over the cz competition is the ar15 styled controls, modularity, and the fact that it fires from a closed rotating bolt which probably means it's a little quieter suppressed. I could take or leave the mostly aluminum construction, Glock proved over 20 years ago that it's unnecessary. Just more sig junk. I'd pay $1200-1400 for this gun, tops. Sorry I'm not sorry for being honest.
