I would recommend a G20 for a first 10mm if you are worried about arthritic hand problems, I can shoot my G29 compact 10mm with ease and no hand pain and it is very accurate. The 29 is probably the most accurate small or compact model handgun made for combat shooting. But that is not to be confused with target ultra small groups. My Para will shoot a smaller group at paper targets from rested or braced slow fire, but when not trying to shoot for small group and just knock steel targets or bowling pins its better then my Para all due to recoil.

I have shot very hot full house 155gr loads in my Glock faster and more accurate then commercial loads in my Para, only down side is the over sized and none fully supported chamber leaves 10 worthless empties on the ground. These were loadings for a 610 revolver and were pushing past anything DT sells.
