As a carry gun I would keep the firing pin block and I do on my C100.
That said the ultimate range trigger is an SA with a flat blade trigger (pretravel and overtravel screws) with the FPB removed, I have 2 guns in this configuration and had a third one and they are all beyond what you can acheive with DA/SA 3mm travel and crisp break, almost no takeup and no, nada zero overtravel.
My carry gun the C100 is SAO with a FPB in place and I have no worries about it. If it drops I am more worried about damaging it than being shot by it.
I see you posted while I was typing.
If you still have time, ask david to add some FPB lifter springs to your order, I keep spares as they are tiny scissor springs and can fly out when you are reassembling the gun.
Also if you ordered the straight blade trigger (it is a great choice) make sure you allow enough takeup on the pretravel screw to allow for the FPB lifter to reset. Stuart and David probably already told you but the reset for the FPB is further forward than the reset for the hammer. And check it with the slide on since it actually changes between slide off and slide on.
No one wants to need their gun and not have it go bang at the appropriate moment.
