I spoke of the 2" Model 10 in the other "Snubnose" thread. At about the same time I was putting that snubby through its paces at work, a range-rat buddy of mine from FBI lent me one of his armory's Model 13 x 3" 357 Magnum revolvers. I had use of it for 5-6 months, and did not carry it on duty or for CCW usage. I DID shoot it extensively, though--and I loved it. I put the same set of grips on it as I had on my M-10 x 2", the Pachmayr Compacs. I put several hundred rounds through it, about half 38 Special +P (reloads that duped my shop's carry load, 110 grain JHPs +P). The other half was an amalgam of 357 Magnum loads, esp. Winchester Silvertips or reloads that acted like them with 146 grain Speer half-jacket SWCs. My intent was to buy a Model 13 or 65 x 3" for my own use, but a cash conflict ran counter to that plan. I had money to buy EITHER a newly-approved 45 ACP OR a new Model 13/65......but not both. I opted for the 45, which I certainly don't regret......but I do regret not getting the 3" 357 AND selling off the Model 10 x 2". Not among my more stellar decisions, for certain.
I have handled and considered one of the 3" L-frame 357s. I can manage the existing 686 x 4" in a shoulder rig comfortably, and that is my usual back-country rig whether on or off pavement. The 3" K-frame is appreciably smaller and lighter than the L-frame platforms, though I recognize its load limits. If the Models 13 or 65 x 3" became available again, I would snag one.
