I went and put 100 rounds of tula fmj through it yesterday without a hitch. It does seem to have a little more bite than the g21, as for accuracy they shoot the same, dead on. I ordered a foxx holster for it to try out, reviews i read all seem to be good, hope i'am not disapointed.
My G30 is my daily carry and I love it! It is snappier than the G21 with the right rounds in there; I had some 185 grain jacketed hollow points that I normally ran through my 21 and when they went through the 30 you could feel the difference! But it is such a good shooter; I'm going to work it into my IDPA rotation next match or so I like it that much.
