If someone asks about DA/SA 9mm's to take a look at, let me ask you, which post is more useful?
"I like my Beretta 92FS, the DA is long and heavy but the SA is real nice. It is a big gun but for HD and range use, it is a soft shooter, quite accurate, and smooth, the slide feels like it rides on lubed ice. Some people don't like the safety/decock so that is something you have to learn and get comfortable with, but overall I think it is a great gun!"
-- OR --
"Glock. 'nuff said."
I think that is the type of behavior that turns people off.
