I have a Gen4 G22 .40 cal and, I have also got a Lone wolf .40-9mm conversion barrel (and magazine). My questions are: 1. What are some of the good and inexpensive range rounds in both .40 and 9mm that I should buy, and where can I purchase them? 2. What are some specific brands, types etc of .40 and 9mm that I should stay away from? Is there anything that the Glock (and specifically my setup) doesn't like or isn't good for it? Basically I want to stay away from any round that my gun doesnt like or is bad for certain parts, and would also like some help finding a good value on some ammo that my gun does like. Thanks!
