The SP-01 is a well designed, ergonomic near perfect, super reliable pistol OP. I enjoy my SP-01 Tactical very much. It's easily the softest shooting 9mm I know in existence; at least that I've shot and I've shot a lot 9mm pistols.
Get some VZ grips, all the Meg-Gar mags you can buy and a good CCW holster, (Comp-Tacs "M-Tac" is my favorite.) Since I already have a P-01 for CCW the SP-01 is the dedicated upstairs HD pistol... outfitted with a TLR-4 and it fills the roll nicely. IMO, it's the perfect Home Defense/Range/Do it all 9mm pistol. If you really can't work around the decocker then sell it and get the standard SP01, but I wouldn't. I went from a G27, to an M&P40c, to the P-01 for ccw. The decocker has never been an issue for me in operation, fast draw and fire, or anything else. Honestly, I prefer all hammer fired semi-autos have a decocker with the exception of the 1911. YMMV.
