The M&P?
Both Flint City, going with the full size M&P 45 and Detroit City have gone with the Smith & Wesson M&P.
As for the triggers, I teach firearms and tactics at the Flint Police Academy, am also the retired Director, the Flint officers going through the Academy with the M&P 45's have had no problems what so ever, both male and female.
I have an M&P 45, full size with the thumb safety and have no problem with the trigger. I carried a cocked and locked Colt Government Model and later a Commander, both in 45 for 26 years on my old department, from which I retired. Carried a Colt in the military for three years prior to that. The M&P trigger is fine, just shoot it and it will smooth out.
Most people buying all the after market triggers and other gizmos that are sold don't need a match grade trigger for their purpose. This is not a target pistol but a combat pistol.
I carried a Glock 23 for the last 13 years as an officer in Flint, it was ok but I think the M&P is a better pistol.
I am a Glock, Sig, S&W, Colt and Remington Armorer, with 46 years on the job and a police firearms instructor since 1975. Have also been shooting in various handgun competitions with various revolvers and pistols since 1965, so I have some small amount of experience. I know, that and a buck sixty-five will get you a cup of coffee at Mickey D's!
Just trying to add some insight.
Spend the money for ammo for more practice and less on gizmos. Sigs are expensive, need he trigger return spring replaced every 5000 rounds. Glocks recoil spring needs replacement every 5000 rounds also, priced equal with the M&P, but has been around longer, that's why all the agencies are going with it. And I have seen both Glocks and Sigs with what may be called a crappy trigger, but they are combat guns not match pistols.
Also like the other gentlemen stated the change over on firearms for an agency is expensive, especially when the leather is added.
And with that, long live the Model 10 M&P 38!
