Lately arthritis has been chewing up my back when I go to the range. I am shooting my SR1911's with a modified Weaver stance (right handed). My right foot is angled @ 45 degrees behind my left foot and I am using the bent arm hold. Lately I have been having problems with my back, 3-4" above the belt line, leaning into my stance. I do not like the isosceles stance and have tried it however a bump from behind would throw you off your target. I am guessing but I believe my right foot is about 12-15" behind my left foot. Does anyone have any ideas of how to change or modify my stance to help prevent some pain relief. I am seriously thinking about getting a nylon style "lifters" belt and wearing it while shooting however, firstly it is too hot to wear at the range and not practical while EDC. Any suggestions would be greatly appreciated except from VT cuz he will tell me I am just too old. Might as well get my yanks in Bob. I constantly clean the range so I am not standing on any loose or expended rounds. Any help will be greatly appreciated. Thanks to all!!
