I just bought the Glock reference handbook and was just skimming it over when I read that they don't recommend converting to .357 Sig, unless you have a 3rd gen or above. Something to do with stronger rails? I'm kind of pissed because I have already bought my Lone Wolf barrel,along with a few boxes of ammo, and now I'm worried that I could damage the frame. Any thoughts from you Glock Veterans? Thanks!
