Smith & Wesson M&P 5.7 Series

Gas operated......hmmmm. Wonder if this helps with the brass shoulder lengthening/deforming that we see in all the blowback guns? If the fired cases come out without the lengthening it might be a great gun for the 5.7 reloader. Buffman....when do you get your test copy??

Boy, I really want to see a spent case.....both normally fired and suppressed if possible.

By now I'm sure the range brass gnomes have scooped them all up. Sorry...

Any chance you looked at some to see if the shoulder moved like the blow back guns do?

Post a picture of some of the spent brass please. Thanks and congrats on your new pistol.

Thanks for the pics. That's the best looking shoulders I've seen on fired brass from almost any 5.7x28 gun, suppressed or not. You may have convinced me to buy a S&W pistol for the first time in decades. Thanks again!

I'm still interested in the S&W but recently I've seen 3 different postings on different forums where people shooting them suppressed have destroyed suppressors. The common belief was since the suppressor is mounted to the sleeve and not the rotating barrel that this may have been the cause. I'm still reading about them but wanted to get this out.
