I switched from Glock 34 to CZ Shadow Custom. You have to train some what on the Da to SA pull, my biggest problem was engaging the safety on reloads because I wasn't use to having a safety. But other than that it was a good switch, I love my G34 but I find it easier to shoot my Shadow faster and more accurate. The grip is so comfortable better to me than a 1911 even and the all metal gun makes recoil very tame. It's all personal preference but if I had to shoot one and sell the other I would sell the Glock.
