Shot through 7 mags of ammo last weekend mostly target stuff PPU, Blazer etc, but I loaded one mag up with the hot stuff - UW 180 grain. The first couple of shots went off without a hitch, but I had trouble with 3 or 4 out of the 15 rounds feeding into the chamber, thus requiring me to push the slide forward to feed the next round. I had no issues with the other 6 clips of ammo, which leads me to believe the issue was ammo related. I sent Underwood an e-mail and Kevin Underwood was quick to reply asking that I call him, which I did but still waiting on that call back. Being a new G20 owner I was curious if anyone else experienced a similar issue when shooting Underwood.
