Took delivery of a .25 GK1. Tuned it for a mag (17 rounds) on a fill. Settled on 310 bar fill which produces great results. This is my second GK1 and I’ve come to see these pistols are absolutely crazy good. I’ll be trying the 25.39gr Kings, 33.95gr King Heavies and the 29.32 JTS Semi-Dom pellets. Here’s the string with the 25.39gr:
