I use a 75B Shadow in SSP, a S2C in CCP, and a steel frame P-01 in CCP. All of them have safeties and I manually lower the hammers for a DA first shot. You don’t have to shoot the first shot in DA for CCP, but the safeties on the S2C and P-01 are so small that I can’t manipulate them reliably. Also, that is the way I carry them, so that is the way I shoot them in competition. The only nuance is that per the IDPA rules: “If the hammer must be lowered by pulling the trigger and manually lowering the hammer, the hammer will be lowered to the lowest position possible.” The hammer can’t rest on half cock. I have never had an issue manually lowering the hammers.
