The Pug is about as small as I want to go. The 1-piece rubber grips do a pretty good job of keeping the gun from squirting loose. The sights are usable. I am more accurate with my Black widow, but I have a lot more practice with it, too.
The best thing about the Pug is you can hide it in your hand. Gotta walk 5 blocks to your car in a crummy part of town? A Pug in the hand makes the trip less stressful.
