C. Are .mil or ex military with little or no love for weaponry to begin with..
Hmmm. Rather all inclusive with that statement with out justification. Here I had been a Direct Support repairman and Armorer for the Army for several years. I tend to love weaponry, so that really is inaccurate.
However having repaired many hundreds of them, and serviced several thousand I can offer some insight in to the finer workings of this pistol.
For a shooter, it shoots well. I would say it shoots as instinctively well for non proficient new shooters as well as the vaunted 1911A1 series. It is very forgiving in the accuracy department.
Reliability.. This is where I will kick up a dust storm. When its kept free of dust and grime and the like, including the overuse of oil or getting it wet it is flawless till high round counts. However having seen many, many cracked locking lugs to outright failures it gives me pause.
As to the cracked frames you have heard about, yes it was related to very hot ammo in some high round count guns. All current incarnations of the pistol have an addition to the frame and the slide on the left side of the pistol to the rear that looks like a big circle. That was added to keep the slide from embedding in to your forehead if it fails.
For a military side arm it is what it is. I think that perhaps there are better tools for the jobs at hand, but they are serviceable enough. And the Army does keep floating proposals to adopt a different pistol/caliber round.
My personal misgivings however have to do with failures of springs, broken firing pins and other problems. I've seen the trigger bar spring lost more times than I can count, as well as that spring itself failing. Just a bent up piece of wire. And for a weapon that is shot little in the military, compared to a rifle, the M9 is serviced at a much, much higher percentage than the M16/M4.
Now again, yes the over all percentage of malfunctions due to bad parts is low compared to the body of how many I saw for yearly services. But it is high enough that I have some serious misgivings in recommending one.
Does that make it a bad weapon to use? Not necessarily, but I've had enough experience with them to say I would not go for it myself. But as you see in this thread, many many people swear by them.
Shooting them as others have stated is rather easy and it is easy to shoot them well. I would classify them as I would not recommend anyone to purchase them. But I would not say not to buy one either if that makes any sense to anyone. I'm not against Beretta at all with this either, I like a lot of their products and they are all engineered well.
Just my thoughts and observations on this.
