Interesting to see both sides are used.
I wonder if you know who GF1 is?
I don't know who GF1 is.
Sorry to disappoint, but I’m not in the ACGG nor am I a gunsmith by any stretch. I am a lifelong user and hunter though.
As my profession has come up here, for the record I am an Air Force retiree (32 years, 7 mos, 2 days in service). “GF1” is the abbreviation for “Gunfighter 1,” the call sign of the commander of the 366th Fighter Wing, at Mountain Home AFB, Idaho. My departure gift from downtown friends was a registered brand, GF1. Minor mystery solved.
