I just picked up a Smith M&P 45 compact for use as my every day carry after selling another rifle I had no use for.
I so far have fired about 100 shots of mixed fmj and hollow point bullets through it with no problems at all. the back strap is interchangeable with 3 different inserts for different sized hands and is very comfortable after adjusting for personal preference. I am still waiting for a Crossbreed Iwb holster to arrive so have not been able to carry it yet but it should carry very well. It is nearly the exact same size as a Glock 19 for reference.
I prefer the .45 so am willing to give up the bullet count over some of the 9mm in the same sized package.
I also purchased another .45 at the same time but will report on that one later.
