No Glock is sissy. If you have your heart set on a nine, but don't want the full size frame, I'd strongly suggest checking out the
Glock 19, which is the compact frame. (You're looking at the sub-compact).
I carry a
Glock 23, which is the compact frame .40 ... better one-shot stop percentages (upwards of 95-96, IIRC) than the 9mm with CorBon 165 grain hollow points.
The compact frame glocks are easily concealable. It's all in the holster. My preference is for a DeSantis fitted female paddle style holster, while slang prefers a Kramer Handgun Leather belt slide style for his
Glock 30 (Which is the same frame size you're looking at in an undeniably manly caliber).
