I love them too.I note that your gun has one pin flush and 1 proud on the receiver rear below the sight. My data base shows this was done only 23,434- 25, XXX. Does yours fall in that range? Earlier and later guns had both pins proud.
Tim and Greystonedog,
Thank you for the excellent photos and information. I have not observed any guns in the serial range above so I don't dispute or disagree with either of you and thank you for the information. I have studied this pin confusion. 22/32 Guns with one proud pin USUALLY ONLY HAVE ONE PIN which is probably the case Tim for your new acquisition since it's outside Greystonedog's serial range but pls confirm for the record as follows:
If you cock the hammer and look from the rear at the top of the firing in the hammer channel on a two pin example, you will see the 2nd pin crossing over the rear of and retaining/orienting the firing pin which has a flattened surface at the top of its rear tip and a square front striking tip. On a one pin example you will observe that there is no 2nd pin and the firing pin is fully round including a round front striking tip; a different style firing pin. The single (front) pin retains the firing pin plate in the recoil shield.
FULLY ROUND FIRING PINS:
Pre war 22/32 Heavy Frame Target, 22/32 Target ('30s vintage), Kit guns and post war transitional Target and Kit guns have 1 pin and the fully round firing pin.
FLATTENED FIRING PIN:
Starting with the Model of 1953, 2nd improved I frame, the flattened firing pin with the 2nd proud pin was introduced.
RETURN OF THE ROUND FIRING PIN:
The flattened firing pin was subsequently dropped in an engineering change that reused the fully round firing pin of the pre war guns with one proud pin on the side of the frame. I have not been able to pinpoint when the change was made and of course like every other S&W change it was a transitional event. However, I have a sense that the return to one single pin (proud) with fully round firing pin coincides approximately with the change from the I frame Mod 34 to the J frame Mod 34 identified with a "-1" in 1960. I have not observed any J frame 22/32 kit guns with two pins, proud or otherwise.
CAUTION, BEWARE OF REFINISHED GUNS:
Refinished Mod 1953 Kit Guns originally having two proud pins will often be encountered with the forward pin proud and the smaller rear pin or both pins polished flush. The 2nd pin flush can be construed to be an original factory variation and may be as you say, Greystonedog, if observed on a non-refinished gun. I would love to know if any of the guns in the serial number range in your data base were refinished but don't know if you recorded that.
NOT DOCUMENTED ANYWHERE:
This 2 pin/1 pin issue will not be found anywhere in the Jink's or SCSW books.
I hope this helps and as usual I am always open to further evidence in the unending pursuit of complete knowledge of S&W firearms.
