I own a CZ75B in 9mm -- nice gun, really freakin' accurate; I can imagine the SP01 being just as good! It should be accurate enough for Bullseye (3" groups at 50 yards), although its fixed sights make this a little difficult. to adjust for elevation and windage. For a semi-auto, the trigger is fairly decent in both single- and double-action, although I think my Beretta 92FS's trigger is better. I've replaced the trigger with one from a CZ85 Combat (adjustable for overtravel, old-style curve to the trigger), so I can adjust the overtravel out of it to use it in single-action only, or I can adjust it to be able to use the double-action feature. Internally, the SP-01 should be the same as my 75B, and externally it looks to be even better, with its front/backstrap checkering for a better grip (the FS/BS on mine are smooth) and upswept beavertail (mine is not, although I've seen 75Bs having this upswept beavertail recently). I don't care much for laser/flashlight rails on pistols, but that's a nice option if you feel the need for it.
I have a couple Ruger Mk. IIs (a blued Target 5.5" and a stainless Competition Target 6-7/8") -- also good guns. Very 'workhorse' type guns, with the ability to be dry-fired without damage (although, you know, everything in moderation), and certainly accurate enough for Bullseye. They'll feed most any ammo I care to buy, although my Mk. II Target choked on a bunch of crappy Winchester SuperX this weekend (and I figured it would; I was just trying to get rid of this stuff by burning through it as quickly as possible). I'll just stick to the Wally World Federal Bulk Pack (#750), which feeds nicely in all of my .22s and is pretty accurate for a bulk ammo. Also, the extractors wore down on all of my Mk. IIs (I had four at one point) which caused all manner of FTFeed/Fire/Extract/Eject issues, and they were all replaced with Volquartsen Exact Edge extractors--no FTEs (due to the extractors) since. The triggers needed a little work (chiefly replacing them with adjustable triggers, and stoning the hammers to lighten the pull), but that was no big deal, and I was able to do the replacements by myself.
S&W 686? There's a good gun, and with a little work, the triggers can be far better than any auto. With an appropriate set of grips (mine wears a set of Kim Ahrends combat finger-groove grips) and its 6" barrel, it'll make .357 Magnum easy and even pleasant to shoot. Of the three guns you listed, I support getting this one the most. If you get a later one with a drilled and tapped frame, you can easily mount a red-dot or a scope. Combine that with some good .357 loads, and you've got an excellent hunting weapon--or a good Bullseye gun with some .38 wadcutters: I shoot revolvers in Bullseye competition, and, once I get it set up, my 686 will be my centerfire gun (with my other two being a S&W 617 for .22 and a S&W 625 for .45).
Overall, I think the three guns you've chosen are an excellent set and can cover a wide variety of uses. Go for it, and let us know how it goes!
