For the past few months, I've considered buying a Sig 320 M17. Not because I don't like 1911s anymore (far from it), or because I'm a military guy (far from that, too), or some military wannabe. I just figured if the Army adopted it as it's new sidearm, then it's probably worth looking into.
I've visited a few LGSs in my area, but only one of them carried it. So yesterday I went and purchased one. I'm busy reading the User Manual and getting familiar with it. After that, I'll take it to the range.
I thought it was reasonably priced (after tax the price was under $800), especially since it came with one 17-round and 2 21-round magazines. The grip is very ergonomic and comfortable to hold (not as good as my 1911, but better than my Glock), and easy to disassemble (also better than my Glock). The sights on it are very nice and easy to see.
As someone mentioned in another post, the M17 was found to have some issues with accidental discharges after excessive dropping. My M17 was made with all the changes (lighter trigger, sear, striker, and a mechanical disconnect) to correct those issues.
My M17 the 320F-9-M17 model, meaning it doesn't have a manual safety. It's my understanding that the M17s purchased by the Army have manual safeties, but the person at my LGS said they don't order the ones with manual safeties because there's not a large enough demand for it (he made the questionable comment that "you should be so safe you don't require a manual safety").
I would have preferred one with a manual safety, but it was by no means a deal-breaker.
It seems like a very sturdy, rugged gun. And while it is modular, I'll probably never bother swapping out the lower receiver, barrel, or anything else... I'll leave that kind of thing to others.
I wish they would have made this in a blued/black finish rather than Coyote Brown, but that wasn't a deal-breaker for me, either.
Overall, I'm rather impressed. I'm looking forward to time on the range with it.
All that said - it's still no Colt M1911A1.
