I did a total focus on 1911s today. I took out my RIA 22TCM MS Ultra and my RIA 9mm MS.
I fired a total of 200 rounds - 100 rounds of TCM9R (using one OEM RIA 9mm mag and 3 Wilson Combat 9mm mags); there were no issues. I also fired 100 rounds of Wolf 115-grain from the 9mm 1911...there was one stovepipe but no other issues/fails.
I also caught some copper jacket in the abdomen and arm. That was NOT fun! Fortunately, it didn't break skin.
I plan to take out the same guns tommorrow, again, only I will fire standard 22TCM (with one mag...I only have one that fits 22TCM).
