I recently sold my G22 to fund a G20sf, which I picked up yesterday. This thing is great! I took it out to hunting club after work and burned through 100 rounds of Blazer without any malfunctions. I really don't notice much more recoil than the 40 S&W. As some have said, it's more like a "push". Anyway, if you've been thinking about trying 10mm, do it! Just be prepared to go broke if you're like me and don't reload. I think an aftermarket 40 S&W conversion barrel would be helpful.
