The galco miami classic holster that I have tends to shift around a lot when I wear it, and since I generally carry the uspf with 12 rounds of 45ACP the butt of the gun shifts down to a point that it doesnt conceal well. I have tried adjusting everyhing on the holster, but the weight of the grip is just to much for the design of the holster to balance. Cost not being an issue, can you think of a holster maker that makes something that would work for me? Since I know this isnt going to be cheap, I would like the best so I buy once and cry once. I would like something with wider shoulder straps to help with comfort as well.
