I want to start shooting IPDA and a bought a glock 19, and had the grip reduced, then my friend said that will place you in a upper class, is this true? what else will change the class rating? fiber optic sight? 3.5 lb trigger bar? grip tape?? hogue slip on grip?? just wondering if ill have to use a bone stock glock or what. thanks for any info.
