"I'm new to USPSA and start my second 7-wk 'league' this month. I shoot the 75B, production. It was pointed out to me that USPSA rules require "fully" decocked for first round.
I have small hands and would much prefer the 1/2 cocked position."
According to USPSA Rule Book 2008 8.1.2.2 Ready condition Double action : Chamber loaded, hammer fully down or decocked.
If your gun has a decocker, then you use it, the hammer does not have to be fully down.
