Poly Frame warp warp?

SO i've had my M&P 9c for over 6 months. I love the firearm, shoots great. mostly stock, i clean it after ever range use. only issues i have..

1- when i first got the firearm, i noticed the finishing work was " ehh ". most on the rough edges. and never filed the casting points

2- the annoying trigger ( but im use to it now )


Anyways the front part of the frame is separating more and more from the slide... not much , but i notice the gap. Maybe at least 3-5mm or more gap between poly frame and the slide. I probably shot 500rnds through the gun. and for the most part it runs flawless. but the gap is bothering me.

Has anyone notice this, or is it something i should i contact S&W?

More than likely you are looking at a thing that has been around as long as the M&P, and its actually an optical illusion, it looks like the frame is drooping down at the front of the slide. A number of people have looked at it, carefully measured it, and found that while it looks like it droops, it doesn't. I tested this on my own pistol and got the same result.

No separation on any of ours, with many thousands of rounds fired, and the oldest being over nine years now.

Apparently it's common with some polymer pistol frames. Do a google search for "glock frame droop" and "m&p frame droop" then select "images" and you see many pictures of polymer pistol frames.

I checked the gap on my 40c with my calipers and it came out at 2.17mm, so if yours is 5mm, that seems like quite a bit for the 9c's short dust cover, you may or may not want to have it looked at. I've read where some have been replaced by S&W and others have been told they're with-in spec.

Mine and a lot of others look like the frame is drooping, but put a straight edge on it and its perfect. So while mine looks like its drooping, a straight edge says otherwise.

Well guys, i'll admit..

Its a bothersome illusion... we measured it with new off the shelf units, and my M&P is perfect!

a shot sticky should be made to tell others

I do notice this on my M&P 4.5" 45. I have a Streamlight, light laser combo on it though.
