Been carrying a model 65 or a Coonan for twenty plus years, decided I wanted more fire power with out reloading, Bought my first Glock last week, gen4 23. The grip feels good in the hand, but feels like a cheese grater on my side in a IWB holster. Thought about wrapping the grip with some black 3m self stick bandage, but don't think it would hold up long and probably have to swap it out pretty often. A under shirt will take care of the problem in the colder months, too hot to wear ten months out of the year where I live. Any ideas?
