Great gun very comfortable to shoot and most importantly shoots straight.

Was lucky to have been one of the first to get one of these. Compared to a 220, this SIG 10mm is a relatively soft shot! Not sure if it's due to the polymer frame, but I think this is a much more comfortable pistol to shoot. Might also be the grip - which is different from those of other 320s that came before it (even the X-Frame grips). The "trumpeted" base of the grip mod seems to help in a way that a flared magwell would on a small-framed gun: where your bottom two fingers on your dominant seem more firmly clamped on to reinforce a solid grip.

No qualms about the pistol itself. I've had perhaps one FTE, and only on my first mag (S&B 180gr hp).

My only gripes are about the magazines. Made by SIG and not Mec-Gar. First, it receives all 15rds, but with zero spring slack: the last round will be a very tight fit. Second qualm - I've dropped the mag once as you can't be finesse with inserting the mag into the well. Pretty much need to do an additional / brute slap of the mag (as is taught to beginners) - which I imagine would be a concern in case your life would depend on a fast and sure reload. (e.g., for those of use who would use this as a duty pistol).

Other than that, loving this gun. Still shooting it with irons, though I do have a Romeo 2 waiting, once I get tired of that round-notched dovetail :)
