I have a Buckmark Camper Whisper also. It's very accurate. The trigger is pretty nice. I shoot it suppressed with a tac-65 and a ss sparrow. Never had a problem.
I have the Buckmark w/wood grips. Love it. Also have a Ruger SR22 -it is a HOOT to shoot as well. Both have their specific "characters", and I use them to introduce new shooters to our sport.
The grip is nice, but makes reassembly a little harder. My URX shoots just about anything. I added a Hi Vis front sight, as I'm used to dot sights on my sigs. The front sight is the same screw pattern as a Ruger MKII (at least on mine).
