I found a local IDPA (south Cuyahoga sportsman club in ohio) I have state firearms training and was trained a certain way and would like to keep it that way. i have been to clubs that insist on changing that. i have never shot IDPA but think it would be fun to do but don't want someone telling me i have to shoot a certain way. i was at a local club where a guy who obviously watched too many youtube videos try and tell me i should shoot izraly style and that what i was trained in is obsolete. i ended up leaving. with IDPA do you have to shoot by their rules? someone telling you how to shoot? I also would like to know about my set up. i have a s&w M&P 9mm fullsize both duty and cqc holster.
