i think i can shoot well enough with most guns to pursue one make/model and get better. ones ive considered: beretta 92 glock 19 USP compact 1911a1 sig 228/229 my budget is roughly $500 (i know some of those guns are more). what would OT recomend? i know to go with what i like the most, and to be honest berettas, H&Ks, and sigs all feel great in my hand. also, has anyone here done IDPA? tips and tricks ?
