I respect the views expressed, but I like my Beretta much more than I'd feared that I would. I do have the current FS sort with the slight backstrap difference, and this makes it fit my hand better than the M-9's grip.
My son did three tours in Iraq, and never saw one break or fail, unless cheap aftermarket magazines were used. Beretta or Mec-Gar mags seem fine.
As for lethality, he dropped nine men with the M-9 and a Browning Hi-Power, the latter gun carried while working as a "contractor." (Mercenary soldier, to be less PC.)
He is an exceptional shot, and pretty cool in battle, I suspect. He'd rather have had JHP ammo, but the issue "ball" ammo worked, with good placement. He did fire several shots at some targets without waiting to see if one shot would suffice. But a shot in about the solar plexus did drop one insurgent with a Dragonov sniper rifle, as he ran across a room. A medic ran over and tried to save the man, but he died within a minute, scrabbling around on the floor. He was unable to offer battle.
The Beretta seems exceptionally reliable, even more so than the .45 that it replaced.
Because it has a DA trigger for the first shot, it is not a big deal if the safety get swiped off. Many users never employ the safety, unless maybe while loading the weapon.
The M-9 is bulky, and the recoil spring probably should be changed about every 3,000,rounds. Current civilian locking blocks seem far more durable than the early ones, but the military probably uses the old ones. One IPSC shooter says that he has over 100,000 rounds through some of his Berettas, with no frame or slide cracks.
Capt.Scott O'Grady did complain about rust on his M-9 while evading enemy forces after his F-16 was shot down over Bosnia. I think that aircrew should have stainless handguns.
Overall, next to the CZ-75B, I think I like the Beretta the best of the modern nines.
