I have had an SW9F for a number of years.
It goes bang every time. Will feed and shoot anything.
I like it as it has a better grip angle for me than the Glock.
Other than that is is a Smith & Glock.
I had one small problem and S&W took care of it and then some.
( customer was shooting it in a match and flicked the front sight off. Sent Smith an E-mail, they had me send it to them. they added a night sight front that I asked for and sent it back in less than a week.)
