I'm not sure my 64 YO knees will hold up to 3-Gun. USPSA is fine so far and shotgun IDPA matches are no issue either.72 now! I used to shoot almost all the games photoracer does but now mostly the shotgun games. Another 8 years makes a big difference. My younger buddies used to laugh at me even back then trying to get up and down shooting some stages in USPSA and IDPA.
