I thought I'd found another Model 18. But the store had it listed correctly, a Model 17-6, with a four inch barrel and without full lug under the barrel. Of course I only figured this out after looking at my SCSW. I'm very fond of four inch K-frame 22's and am always on the lookout for a "shooter" 18. Anything special value wise for this four inch 17 w/out the lug? Naturally, it looks just like an 18-4 without the pinned barrel.
The SN is something I couldn't find in the SCSW though. Did I just not see see this in the book?
