I recently purchased a P-09 and P-09 and love them both. My only complaint would be that the DA on both pistols are pretty darn heavy. The pistols are going to be used as self-defense tools and I'd like to lighten the DAs on both a bit but I don't want to do a mass replacement of all of the internals (although I did do this on a CZ 75B with CGW parts and the pistol is absolutely fantastic).
Will I be able to get away with replacing the stock parts with a CGW yellow 18 pound hammer spring, a lighter firing pin spring, and a reduced power trigger return spring only and still have reliable pistols (without, say, replacing the stock FP with an extended FP as well)?
