It seems that Recoil and Recoil sensitivity with the R9 creep up from time to time here at the campfire. In fact, one poor soul is actually selling his almost new R9 over in the classifieds because he can not handle the recoil.
If you have trouble in this area, please seek help from a professional or experienced shooter at your local gun range. They CAN help you in minutes to an hour.
Just like women afraid of 12 Ga shotguns. They usually are not trained properly on technique. Once given the proper guidence, they can shoot for hours.
Same goes with the R9 (I don't know about hours), all it takes is technique and your good to go.
I have mentioned ad nauseam about my personal hardship with my hands and arms and have overcome the recoil with no issue.
Before you consider selling, or if you are struggling, PLEASE ask for help. You will be so glad you did.
In fact, if anyone is near or willing to come to East Texas, I will spend all the time needed teaching you the proper techniques to make you feel comfortable shoooting the R9, free of charge.
Just ask.
