I had a Gen 2 in 40 cal. Had a lot of fun with it but need I say, sights, some sights, no sights. A fat man stands no chance to squeeze his face in tight enough to use them. Bye the way, that thing kicked like a mad mule.
When I bought my CW380 a few years back it was a jamomatic. Called customer service about it and they said I needed 200 rounds break in before they would look at it. Well a thousand rounds wouldn't have fixed it so I told them it had over 200 and sent it to them. Came back in about two weeks...
