I love them and can't wait to get my hands on one of the new production. That said, they have their problems. I had a Mustang Pocketlite; after about 1500 rounds of pretty mild cast bullet handloads, the steel barrel was peening the alloy frame where the breech came down on the frame in recoil. Also, there's a sharp edge on the bottom of the trigger guard, that pinches my trigger finger when I release the trigger. I've had three of these things; don't have any now, and can't wait to get another.
