This is a discussion on The M&P 45c (compact) is here within the Defensive Carry Guns forums, part of the Defensive Carry Discussions category; Speculation by a very knowledgeable person on another forum was that most .45 ammo is designed for 5" bbls and shorter ones lead to this ...

Sounds reasonable as a factor. I just shot some cast stuff in a 5 inch gun with the PVD finish-flat blue black, and the gray showed up badly and dulled the fiber optic sight a bit. Some powders are smokier than others, that may be a factor, too.Speculation by a very knowledgeable person on another forum was that most .45 ammo is designed for 5" bbls and shorter ones lead to this problem.

The low pressure of 45ACP rounds results in a less complete burn than high pressure 9MM .40S&W etc. rounds. The result is more crud being deposited on and in the gun.
I normaly shoot an M&P40 or M&P9 using the same powder as my friends that use 5" 45ACP's. Their muzzles will be grayed out after 150 rounds or so while mine remains clean as when I started.
One friend decided to shoot with his light attached to reduce muzzle flip. After 100 rounds the light was useless due to a soot layer blocking light.

I plan on having my 45c finished in teflon/electroless nickel like 2 of my other M&Ps by Robar. This will negate the burnt powder problem. I can't say enough about this finish, it not only makes the gun smoother in operation but also makes cleaning easier.
The 45 compact is now my favorite M&P.

I'm going to be buying my second CCW in the near future and was going to get a Glock, but have been giving serious consideration to the Smith & Wesson M&P Compact line of handguns. I've read a number of great reviews on the M&P series but none really got into how reliable the M&Ps are compared to the tried and true Glock line of handguns.
So how do they stack up reliability-wise compared to Glocks?

I don't know about comparing with a Glock, but Todd Green is nearing 25,000 rounds in his M&P 9 torture test. Check out Pistol-Training.Com or The #1 Compact, Full Size, and Modified M&P Pistol Source :: MP-Pistol.com.Originally Posted by CEW58

What is the height of the Compact 45? Is it the same as the 40 and 9?
Array
It's larger (height) than the 40c/9c, but I don't know the dimensions and I don't own the .45c . . . yet.
Array
M&P 9 or 40 compact is 4.3 inches tall.
M&P 45 compact is 4.8 inches tall.
I held an M&P 45 compact a couple of days ago. It's about like a Glock 9/23 in size, just beefier.

For all us enthusiasts for the 45c and are hopeful for a Crimson Trace LaserGrip for it, I have started a thread at the Crimson Trace forum to collect our requests. M&P 45c LaserGrip Request Thread.
Speak up by adding your request and hopefully it will encourage Crimson Trace to help us.
