Go rent and fire each gun, then pick the one that you like the best. The one that is comfortable in your hand, and you feel you shoot well, then.....well shoot....a bunch.
Good Luck on your purchase.
Practical issue: Went by H&H today. They don't have any of these guns available for rent. They have an SR9, but not an SR9c. I guess that would tell me quite a lot, but I gather the trigger on the SR9c has been improved. Closest I could come to the PT911 would be a Baretta 92.
Any other places around to rent in/around OKC?
