I've got an SP01 decocker. I love the thing. I sent it off to CGW for a pro package and milling for an SRO install. It's mostly a range and local comp gun but I'd use it for home defense too. I think it'd serve both your purposes. Buy a CGW pro package and install it yourself to save both a boat load of money and time (it's not hard, I've now done 4 pro package installs and internal polishings, 3 on decocker models and one on a safety model - one of the installs was sort of a reinstall in my PCR which CGW did first but I wasn't happy with the final DA pull so I stripped it and re-polished it). It's pretty satisfying to do it yourself and there are a ton of great videos out there and CGW is great answering questions. Anyway, with a 13lb main spring you'd end up with a gun that you can easily use for both home defense and the range. Mine has an 11.5ib spring and it has a DA of 4lbs 6oz and SA or 1lb 11oz. I haven't tried an S2 so can't speak to any comparisons but the trigger reset on the SP01 isn't bad at all. Could be a bit shorter on SA but it's just fine when I'm shooting steel or taking my time. That all said, if you really want 2 dedicated guns, get both an SP01 (or P01) and an S2 or even check out CZC offerings seem like a good idea. I'm looking at an A01-LD OR for my final CZ75 based gun for the range and comps but there are less spendy options.
