It's not a bad gun. I carried it on active duty, and owned one on my own. There are some common failure points to look at, specifically the wings on the locking block. But it's user friendly, and accurate. There are better guns out there, but I don't have an issue with the Beretta 92. I did trade it about 18 months ago (the only gun I've let go) and I'm kinda regretting it now. Oh well.
If cost is a concern, you can look at the Taurus version. There are a couple differences like the safety/decock, but it's otherwise the same gun.
I bought one awhile back and find it the easiest shooting handgun I own. Probably because of the weight and smaller caliber. I highly recommend them
As far as locking block failures I suspect this is on heavily used handguns that havent had springs changed.
Locking blocks are rated to last 22000 rounds
