I had posted a few weeks back that I was "10mm curious." I picked up a 6'' KKM barrel and a LW LCI 10mm extractor (actually needed minor fitting to go into the slide but that's another thread all together) and a G20 mag during the recent mag sale. Went to the range with some Prvi JHPs, 200gr Blazers, and 165gr Gold Dots from Underwood. 50 rounds of each. Function was 100% and all ammo ejected as it should with the exception of the Prvi rounds but I suspect that's because they seemed very underpowered. Firing that 10mm stuff is a good reminder that you're shooting a gun I loved it. Thanks to everyone that helped with my questions a couple weeks ago.
