I thought I wanted one of the Pocket revolvers, also, so a few years ago I bought (from a Gunbroker seller) a Replica Arms El Paso Texas 1848 Pocket .31 6" barrel w/load lever and a squareback TG. I am a sucker for the squarebacks. I guess I did not realize how small these guns are, and I have average sized hands with long fingers. I find the 1851 Navy pistols fit my hand perfectly, but the Pockets are just too small for me. I don't like my pinky hanging out in the breeze. I suggest you find one to check your hand fit with it before you spend hard-earned money for one.
BTW, maint1517 now owns it.
The Pietta 1851 .36 from DGW looks very good, IMO. I have one I bought from Cabela's 3 years ago for an absurd one-day-sale price of $170 and free shipping. It really pays to check Cabela's website on a daily basis because one never knows what their marketing folks will do. I seem to think that now that their parent corporation is Bass Pro Shops it won't happen much. Too bad for us worker bees.
If shopping for a used Pietta 1851 Navy .36 type pistol, pay attention to the date code on the right side of the frame. Any frame having a date code of 2014 [CM] or earlier will have the dreaded (in some circles) "tail" grip profile (it actually fits very well in the hand). In 2015 [CN] and later pistols had a more "conventional" grip profile, whatever that might be (check with Nathan L. Swayze's '51 Colt Navies and you will see that there was no standard), and the current detractors have no leg to stand upon, IMO.
If one changes the 3-piece grip (trigger guard, backstrap, and wood) with the newer 3-piece grip style, it will fit perfectly to the frame of any date after 2000.
Any Pietta 1851 .36 pistols prior to this is a crapshoot.
Good luck in your pursuit!
