Guns that are shot alot break. Handguns, Rifles or Shotguns--------you name it they break.
I believe that the Glock is durable however, you hear about more Kabooms with a Glock than any other handgun by far. Will the Glock outlast the Beretta? Probably. Will the Beretta provide a reaonable service life with normal care and the avoidance of excessive amounts of +P? Yes.
The Beretta 92FS is accurate. I have owned Glocks, Sigs and Berettas and I have shot all of them frequently. Two weeks ago at the range, I shot beside a Glock 19 9mm, Sig 228 9mm and a 1991A1 .45ACP. At 7 yards and 15 yards I tore all of them up in the accuracy department in slow and rapid fire. Where they had holes close to each other, I had one big jagged union of holes touching each other.
Furthermore, the recoil of the 92FS is almost non-existent allowing the user to stay on target in fast shooting sequences. The Beretta will digest anything you feed it---low power, high power and in between. As for the size of the gun, the 4.9" barrel makes any 9mm load scream even the 147 gr Speer Gold Dot HP-----my favorite.
Yes the Glock 17 is a tank but I cannot stand idly by while the 92FS takes a bashing. I have tried most of them out there and for a carry gun that is shot a little and toted alot, the 92FS makes sense. In this application, I will put the reliability of it on par with any pistol made in the world today. If you shoot like Chindo18Z, you may want to look at the Glock or HK. Even then, you will have problems since the laws of physics cannot be overcome by man. Again, guns that are shot alot break. Chuck Taylor shot a Glock 17 over 150K and the extractor flew out but that was'nt a failure. You see in Glockland extractor failures are'nt break-downs and when a Kabbom happens it's never Glock's fault although they happen frequently. Blame Adam and Eve for this dilemna. BTW, the grip screws on Sigs will rust just as easily as on a Beretta and FWIW I have had a NIB Sig that would not function and had to be sent back to the factory. I have seen P 229 duty weapons with severly corroded grip screws as well. Frankly, the most durable Handguns I have seen are a customized 1911 and a Ruger P90.
Have a great weekend.
