I have fired the X frame a few times. The recoil is not that horrific but the X frame is considerably heavier than a XDM. It will likely end up like the Glock 32 I bought. The 18 OZ gun gun did not flatter the 357 sig. I can shoot a revolver just as fast. That was my first and last experience with a Glock. When I bought my Ruger P95 I had ever intention of buying a Glock 17. After a firing a P95 a few times I bought it.
