No worries, the M&P isn't for everyone, I own it in 9mm, no issues as of yet, there again, I don't carry on duty, day in and day out as you do yours, in .45, mine will never see the environment that your weapon does.I purchased a 9VE on a whim, and I gotta tell ya I like the little fella. Waaaayyyyyy more than the garbage M&P 45 I'm issued.....shhhhh....I'm getting crucified for not drinking the Kool Aid on the M&P side LOL.....
The Sigma has a great grip and points perfectly. Maybe they should have just used the Sigma as a starting point instead of.......anyway, love my little Sigma!

I also own the 9ve and 40ve, haven't used them for a carry option yet, the jury is still out, before I trust my life to them.
I plan to continue to test their performance in different styles of personal defense shooting, more training.Asymmetrical, CAR, vehicle,and the like. I think the Sigma likes a strong grip, My wife attempted to shoot from a close hip holster draw and the 9ve attempted to double feed, hence jam. No problem, I expected that. All in all, their keepers.
