Only one out of my 4 semi's deserves the top honors as far as undeniable flawless functioning no matter what ammo I throw at it, and also top honors in fit, finish and overall quality completely box stock :
FNX 45T
A close second is my Beretta 92FS , but my Beretta's trigger is tough and has a long pull, the FNX's trigger is a perfect balance of crisp and pull weight.
My G35 Glock also cycles flawlessly, but I just don't like the way it recoils (snappy). I get trigger slap on my finger, and racking the slide takes a very tight finger/thumb pinch to not slip.
