G19... Havent changed platforms since 2005... no reason to fix what aint broke..
from 1999 - 2004 it was a G23....
from 1991 - 1999 it was a G19 (1st Gen)..
my "BUG" has changed several times over the years.. it took me a while to find something that I felt comfortable with, that was reliable enough, and could be carried correctly in a variety of different places (pocket/ankle/on the vest, etc..).. and has been everything from a S&W bodyguard to a beretta tomcat.. I finally settled on a Kel-tec P32 sometime around 2001... and havent changed it since..
Ive owned/own several other pistols.. but none of them have been CCW weapons.. they were either "range" guns, or special purpose pistols (hunting, target, competition, etc..etc..)...
Im a firm believer that you should be comfortable with any/all pistols.. but should stick to one platform, worn in the same place, the same way, all year round for your primary defense weapon.. if you dont have a pistol that supports that.. its time to change pistols.. or your manner of dress..
The only exception I make to this is "gym clothes".. if I am somewhere that a t-shirt and shorts are the standard.. and Im going to be moving around a lot (the gym, out jogging, on the beach/by the pool, etc..)... my BUG usually becomes my primary (better than nothing).. and is carried in a very small (and ghey looking) fanny pack holster..
