If you want a 3" SP101, your choice is the KSP-321X, 27 oz & MSRP $629. I submit the S&W 3" 60 Pro as an alternative:
Sure, the S&W, SKU #178013 23.2 oz, costs more - MSRP $779 - but it comes with attributes that the Ruger just doesn't have: adjustable rear sight, tritium Night Sight front sight, and great wood grips, not to mention the target barrel and better trigger. Sure, it will run you $80-$120 more - but you get 'more'. Both are fine for any SAAMI spec'd .357 Magnums, even if the casual shooter won't enjoy shooting them. The 60 Pro is a great .38 plinker - that adjustable sight really helps. Either model will require a holster - they aren't 'pocket-friendly'. Here is my 60 Pro - bought new locally 1/11 for $631 + s/t - in an S&W Accessories 3" J-frame holster, which it shares with the 3" 63 alongside:
I am sure the SP101 is a good revolver. My experience with my only example, a new 4" .32 H&RM model several years ago, was horrible. It was by far the worst new firearm I had ever bought, QC-wise. Oddly, I had bought a bunch of new Rugers that were well less, QC-wise, than I expected. The SP101 spelled the end here for Rugers - I now have all S&W's, albeit fewer. YMMV.
