Reload! I was loading .40 for my G22, 3.6 TG 180gr at about $130/1k. When I got my G20 I loaded the same loads for 10mm and they shot great. Fun and accurate. But with the 10 you can load from light 40 loads to full power 10 loads. Very versatile round and lots of fun!!! Think about it, you can load 10mm for $130/1k (or less) for GSSF heavy metal! Its cheaper then 45. I will get another 10mm soon.
