just picked my SP-01 tactical 9mm the other day. Looks like a keeper to me. Also bought a tactical light for the rail from CZ, pretty cool and it is nice and bright.
Not sure about the stock recoil spring guide, so I made a couple steel ones to play around with to see which I like better. Also have a couple different springs coming to play with the trigger pull and recoil.
Done a poor mans trigger job with the help of some O rings and or ear plugs. I have to say trigger has smoothed out considerably, but still a bit stiff. By the way Molycote 44 medium grease works very well.
Blued the barrel, I think it looks pretty good.
Anyway enough babble, going to be a fun tinker toy.
