My Glock 29 is considered a sub-compact pistol. It ain't tiny by any stretch of the imagination, but I've found it to be relatively easy to conceal with my CTAC holster. Of course, sometimes shorts and a t-shirt are called for in the Florida sun, so its bulk becomes easier to notice. Hence the purchase of the KelTec P3AT.
Here's a bit of comparison of them for scale (each picture allows the depression of the left most mouse button in order to facilitate image enlargement. For image enlargement lasting over 4 hours, please see your doctor).
Dunno when I'll be able to deliver a range report. Until I get at least 100 rounds through it, I'm not going to be comfortable carrying it, so I'll be trying my darndest to find some practice ammo so I can put her through the tests.
