My first one had a few bugs I needed to work out. Since then I've had no trouble with it except that for some reason after shooting 100 rds or so in a session I have to stop and clean the cylinder or cases start sticking. The second one I bought frankly to swap parts around and diagnose the problems (failure to fire occasionally) I was having with the first revolver. Ended up ordering a new hammer spring and 22 mag cylinder.
Both were purchased during one of RKs $99 sales although months apart. I guess not surprising they like different brands of ammo. I bought the first on on a whim and kept it locked in my truck while I was working. There was an indoor range near where I worked and after work I'd swing by and shoot 100 rds of 22LR. Some guys hit the local watering hole after work to unwind, I hit the local range once a week. Now that I've retired I still hit the range once a week and a 22 usually goes along. Both go along when camping because my wife also shoots. Yes, I have better 22s but RR fills a gap for me, I don't feel bad if one of these gets a scratch from walking through briers or starts to show signs of holster wear.
