Field Strip: Smith & Wesson M&P 5.7

In this field strip video I show how to safely field strip and reassemble a Smith & Wesson 5.7 pistol. This is a mechanically interesting pistols as it uses the "Tempo Barrel System" which uses both a rotating barrel and gas delay operation. I hope this video helps someone in the future who may need information on how to do this or someone just interested in this pistol's operation.

Just picked one up, you're the only person I can find that posted this. Thank you!

[@thetexasgunvault]

You are welcome. This is why I make videos like this. I hope I can help others.

[@ralphcarroll5090]

You do not have to take off the thread protector to remove the barrel from the slide. one of S&W M&P 5.7 unique design features.

[@thetexasgunvault]

Thank you for that information

[@otaviousnickerson4941]

I was going to post this same comment I had my M&P5.7 a month after it dropped on the market and figured that out

[@tylerleteff4364]

Do you know where I can find a complete disassembly video? I have to change the slide stop retaining wire and can’t find a schematic or video anywhere

[@topglock]

Cool video, just cleaned mine up from a couple hundred rounds. Really digging the pistol

[@thetexasgunvault]

I love the design

[@rdm1000]

Appreciate this. There are always a few guns where the strip is a bit finicky. This is one given the less than common setup. Your presentation was concise and well done. Got the 5.7 today and watching you was much better than reading the manual. Saved me aggravation, and saved my wife from hearing an endless stream of expletives. So, win-win.

[@thetexasgunvault]

I am so glad it helped! It is why I make these and I am very happy to read your comment.

[@SCWJackE]

Clear, well paced, excellent lighting and clarity, very good technique, thank you. I hope to buy one soon.

[@thetexasgunvault]

Thank you and I think you will enjoy it.

[@mikehaynes8647]

I just performed my third breakdown and cleaning. I watch this video before every cleaning. I love this gun. It is one of my three-carry guns. My three edc guns are Sig P322 (only with stingers or Punch) CZ P07 and the S&W 5.7. Getting the optic regulated is usually the last step in the edc process. Thanks again for the helpful video.

[@thetexasgunvault]

You are very welcome!

[@archer_duke]

Thumbs up for not calling it gas-operated👍. But unfortunately it is not gas-delayed either. This mechanism is basically a short-stroke recoil operated action as used in most handguns. But the 5.7mm cartridge has too little momentum for a recoil operated action because of its low impulse. Therefore, the additional momentum required is achieved by a muzzle booster. It is somewhat similar to a Nielsen device in a silencer and the exact opposite of a gas delay. The TEMPO system increases the speed of the slide, without increasing felt recoil. The expansion chamber around the gun "helps" the gun to cycle, although it is primarily still recoil operated. The firearm is therefore gas assisted, not operated nor delaied.

[@thetexasgunvault]

Thank you!

[@TheTrueDoomSlayer]

Underrated helpful comment.

[@UraNiUmXXpLoSiVez]

Just what i was looking for thank you

[@thetexasgunvault]

I am glad it was helpful!

[@Tony_Seed]

Thank you this helped me, also my gun was nearly perfectly clean after 600 rounds never cleaned since I got it

[@thetexasgunvault]

I am so glad I was able to help! It is why I wanted to make this video.

[@BaddFrogg777]

Goos to know on the New S&W Platform. A clean running (5.7mm) with a good trigger and truly different interior design engineering. Thin and light with decent capacity. Great for a carry bag or purse.

[@rshollis]

Thank you for the video. Just picked up one and was trying to figure it out.

[@thetexasgunvault]

You are very welcome and I am glad I could help!

[@denvercyclist]

Thanks for doing this! I've been super interested in this thing since it came out since it's so mechanically odd. I hope they make a version of this and some more common calibers.

[@thetexasgunvault]

You are very welcome! I always enjoy making these videos even though they don't get a lot of views

[@littlevillagepythons9636]

Believe manual says to use a 12 point 9/16 wrench to remove and retorque

[@thetexasgunvault]

Thank you for this information.

[@ezequielsanuy8895]

Is basically a desert eagle in 5.7 fn You have a gas piston "tempo mechanism" and a rotating loking system but combined with a polymer grip kinda glock. I had sometimes dreamed about it but didn't know exactly how to shrink the thing down to a concealable or normal size. But now Smith and Wesson already solved the question... Well done very impressed

[@thetexasgunvault]

I am too. I thought they did a good job.

[@no_handle_required]

your takedown videos are among the best, if not THE best.

[@thetexasgunvault]

Thank you so much! That means a lot to me.

[@ctsnider88]

Thanks! still deciding between S&W and Ruger.

[@thetexasgunvault]

I like the S&W a little more.

[@guerlinemathieu5206]

I had the ruger 2 of them i like the mp better

[@joemorganeatmyshortschannel]

Very cool

[@thetexasgunvault]

Thank you

[@brianjones7521]

good video

[@thetexasgunvault]

Thanks

[@arellanojaja91]

did you struggle with the thread protector? mine seems to be torqued down, wont come off at all.

[@thetexasgunvault]

No, mine was easy to get off. I am sorry to hear about yours.

[@rolosnismoz34]

I struggled with mine too it was really dirty from factory. Had a bunch of like tiny pebble rocks & sand.

[@sugariestbaton4848]

Had the same problem. Use a 9/16" 12 point box end wrench if you're still having problems. Unscrewed pretty easily

[@mikehaynes8647]

I had no trouble taking the 5.7 down or putting it back together. I was stymied when I took the pistol down. I did not know what to do. My plan was to clean it. But it looked like it was packed in grease. Do you think I should remove as much of this as possible?

[@thetexasgunvault]

I personally would. That grease can gum things up.

[@williamhooks1473]

Please do a review on Type A Rifles please.

[@thetexasgunvault]

If I ever get a chance I will

[@hughgrection3052]

Has any of yalls S&W M&P 57s got the pretty wild gap above the picatinny rail or dust cover? Mines pretty extreme and I may fix it. But if yall had the same issues I'd like to know as I may just send it back in. I wire wrapped it overnight and it dint fix it. May have to do boiling water next time for sure.

[@thetexasgunvault]

I have seen many with that issue

[@rss5003]

What surfaces of the 5.7 need to be lubed since it runs in a sleeve?

[@thetexasgunvault]

I put a little in the channel and all points of contact. But just a small drop.

[@crx-cs2237]

Did you put the barrel and shroud in a container of clp and let soak?

[@thetexasgunvault]

No, I cleaned it with CLP and a nylon brush

[@diondeleon8436]

How come when I load the magazine after I reassembled it , a little bit of the bullet casing is shown

[@thetexasgunvault]

I am not sure I understand.

[@Noir85Acutual]

My thread protector does not come off?, I have a brand new Smith & Wesson 5.7 and I never shot it before I’ve had the gun for about 30 days maybe 32 days? I disassembled it for the first time using break freeze seal pee to clean it thoroughly and I reassemble it without taking a thread protector off it looks like it’s molded onto the actual barrel itself?does anybody know how else I would get it off without damaging a barrel? If it’s supposed to be off because even the booklet shows it comes off, but mine does not come off.

[@thetexasgunvault]

Have you tried heating it up? I am also assuming you live in a non-AWB state.

[@Noir85Acutual]

@@thetexasgunvault Miami,FL AND NO, Never heated it up. However, I soaked all parks except the hand grip mechanism. In Break-Free CLP, did a good cleaning and wiped clean and reapplied a light coat and assembled. I was able to disassemble and assemble easily with that mechanism attached, I haven’t test, fired it since I disassembled it. However, I do have the blue tipped jacket and hollowpoint ammunition.

[@Enigma37_520]

I dry fired my m&p 5.7 and some kind of little pin popped out of the barrel.I have no idea what it is….

[@thetexasgunvault]

Was it the firing pin?

[@Enigma37_520]

It was.Smith and Wesson sent me the label to send it back to them for repair this morning.

[@tylerleteff4364]

Does anybody know where I can find a complete disassembly video? I have to replace the takedown lever retaining wire and can’t find a schematic or video beyond strip clean literally anywhere. Help.

[@thetexasgunvault]

Sorry I did not make that. I do not know. Have you tried some asking on the S&W forums?

[@billcarey9184]

Was trying to take down and accidentally pulled the trigger. Now slide seems stuck and can’t disassemble. Any ideas?

[@thetexasgunvault]

Hmm.. it sounds like the issue you have is not related to the trigger but rather something is misaligned like the guide rod.

[@billcarey9184]

@@thetexasgunvault I figured it out thanks. I inserted the magazine and it freed up the slide.

How do I get the thread protector off mines won’t come off it’s so tight please help !

I am not sure what to tell you. Mine came off with no problem. Maybe take a heat gun to it?

[@rss5003]

Can you provide link or, direction to where you are getting your 5.7 issues information? I've been waiting to see how many hot rounds Jay W can get through his S&W 5.7 before or, if issues arise.

[@user-cg9nr5rq9u]

А недостатки каковы?

[@thetexasgunvault]

It gets dirty easy and it has a few reliability issues with the magazines.

[@mediamonk100]

Wow what a PITA. I'm sure it shoots fine, but wow, takes forever to field strip compared to a PSA Rock--which takes down just as fast and easily as Glocks do. So many more components and moving parts in the M&P as well, and I can see how the carbon buildup would cause issues. I wouldn't want to have to keep that thing squeaky clean and lubed for it to run right like you have to do with 1911s.

[@thetexasgunvault]

I can understand why you would think that about this pistol.
