Crossed 500 rounds today with my M9A1.
Zero malfunctions.
One stoppage caused by a set of pearl gun shop aftermarket grips failing while shooting WHO, and the weapon still worked allowing me to finish my range session despite the busted left side panel.
No lube ,oil, or cleaning has happened since the initial purchase date . My carry Beretta has about 2700 downrange, but I've cleaned it after each session, so that doesn't count.
I offer this for the folks considering a Beretta, and wondering if the old rumors of "must drown gun in lube" are valid. So far, in this case, it's not for me.
