I’ve had one since 2011.
Pros: high capacity, accurate, interchangeable backstraps
Cons: holster availability (esp w/ lights), it’s not a Glock, slide release is in a place that I apparently touch with a normal grip - so the slide doesn’t always lock back on empty.
All in all, I’m not unhappy with it - if I were I wouldn’t still be carrying it after 9 years - but there’s essentially nothing about it that a G17 doesn’t do as well, or better, except for the 2 round capacity difference.
ETA: I forgot the trigger! It’s probably the best part. Probably the lightest, cleanest OEM striker-fire trigger I’ve encountered.
