Gotta make this fast, daughter needs computer. What can be done to a stock Glock to make it more accurate? Maybe this has been asked to death, but I can't find it. My G22 has a nice tight slide-to-frame fit, and I'm buying a KKM barrel for the supported chamber. they apparently have a unique rifling method that is neither polygonal or (I forget). I think it's a button rifled barrel. What else can I do to wring all the accuracy out of this gun possible? I shoot 180 HST. Thanks!
