I just bought one of these. So far it's been shooting fairly well. Recoil with 10mm is not as bad as a .44 magnum, but a tad more than .357 magnum.
I do not like the grips. They are way too big for my hands as I can barely get on the trigger for double action pull. So I'll be looking for some new grips.
I shot some .40 S&W through it also and it grouped pretty good also. It was pleasurable to shoot also and I think for most shooting sessions I will use .40. I may try a couple of IDPA matches with it also, just to see how well I can do with it. The .40's drop in to the chamber fairly quickly, but the longer 10mm cartridge sometimes takes a bump or two to get them to fall.
All my shooting was done at 7 yards only, this time around. I'm hoping to shoot out a bit further, once the weather clears up.
The target on the left is American Eagle 180 gr 10mm. It shot a bit high. The target on the left is a variety of .40, from Winchester to my own reloads.
Here's a closer shot with the .40 target:
