Evaluate, adapt, overcome - that's my take. Most modern handguns are shootable - you might not like them but they do work. You can work on yourself or you can blame the gun. There are some people who complain about the Glock 21: the grip is too thick, the recoil is too hard, so on and so forth.
It's not the gun. It is you. Train, train, train. Or sell it.
