the rear left corner of my c9's frame beats the hell out of the first knuckle of my thumb (closest to the web) . i've tried holding it different ways , i've tried putting on the hogue grip , nothing seems to work . i don't want to shoot it with gloves because i have decently small hands and it's already huge , but that rear corner of the frame is killin me . i can't get out more than 20 rounds before it hurts enough to stop shooting , anyone else have this problem ? anyone have any ideas on how to correct it ? i'd like my c9 alot more if i could shoot it more than 20 rounds at a time .
