I sold my Glock 22 (.40 S&W) because I was afraid to reload for it once I started reloading. I kinda miss that gun.
I have specifically not bought a 5.7 because I don't want to fool with reloading for it. I have specifically not bought at .22mag because folks without lots and lots of patience cannot reload for it. But I might change my mind on the .22mag and just resign myself to buying factory rounds....
