I own about 12-14 1911's, and 3 CZ's.
all pretty much meet my needs, different models were chosen for different purposes.
but I got to admit that my P-01 is well north of 7000 rounds my SP-01 tac well north of 5000 rounds and neither has had a single issue of any type in function, this is with some 6-7-8 different types of self defense ammo and reloaded range ammo.
I don't think that I have a single 1911 that can match that record?
I have no problem with either platform though.
