The benefit of the standard P01 is in availability (currently at least) and a slight improvement with the trigger feel. The downside is that it's a royal PITA to disassemble as compared to the Omega style triggers With the original style decocker, you need a slave pin to pull the sear cage without disassembling it. And, you don't want to try to assemble a sear cage on a decocker in the pistol. That said, if you buy the CGW parts, buy the S pin and it's not a huge deal to disassemble and reassemble them. PITA compared to an Omega, but not terribly so.
