Depends on what you want the gun to do, otherwise, as well. Range gun? CCW? Etc.
For something you're not planning on carrying concealed, the SP-01 is hard to beat. For the cost of a Glock 17, you get a solid steel handgun that is about as fast as anything you can get that is not set up exclusively for ISPC competition shooting. That steel frame, especially that forward rail, really take the 9mm round's minimal recoil to begin with and make it just about negligible. Fastest non-.22 caliber gun back on target that I own, at any rate.
But, if you're thinking CCW, I'd say look elsewhere, much as I like the SP-01. You can get holsters that will hold it, but better invest in some suspenders to go with your belt if you're going to wear it in an IWB or OWB.
