Got out and ran about 100 rds through the 9mm barrel. Worked like a champ. Just cannot load the 10mm mags to full capacity. Down load it by one and it works fine. Recoil was almost imperceptible (as expected in the big 10mm frame).
In life, strive to take the high road....It offers a better field of fire.
