Uberti 1860 Shoulder Stock Screws

[user 33697]

Hi guys,
I'm looking to replace the two shoulder stock screws on my Uberti 1860 with short set screws. As I am ambidextrous with either hand, both screws really irritate either trigger finger. I could just remove the screws from the frame but it would be awful looking to me with the two threaded holes in the frame staring at me. Ugh! . Out of curiosity, I measured a shoulder stock screw with vernier calipers and found the screw major diameter and screw thread length average out to be 0.212" (5.4mm) and 0.096" (2.44 mm) respectively with 2-1/2 threads. Checking both gunsmith screw inch and metric charts did not show the screw as matching up to a standard screw size. It's possible that the screw could be specially made by or for Uberti to their specification or maybe my aging eyes cannot read my calipers right. As such, my question to forum members is if you have replaced either shoulder stock screw on your Uberti 1860 with a set screw. If so, I would be very interested in the screw size that you used and possibly where you purchased it from. Thanks in advance for your reply.

Just take your screws to Lowes or Home Depot. They have a block with thread ed holes in order to identify the size. Then find the correct plug/set screw in the special screw drawer.

Chuck them in your drill and with a file reduce the diameter of the head as much as you dare. They need a flange to tighten against the frame or they'll go into the action causing trouble. Next thin the head down while still leaving a slot and round them off too. That should solve the problem.

hawkeye2,

Excellent idea! I'll follow your suggestion for making flanged set screws out of the existing shoulder stock screws. I'll be careful when I do it and will blue the flange heads.

I have a very good and talented friend on another forum who has an 1861 Navy 4-screw CFS (cut-for-stock) .36 that he is converting to a J.H. Dance & Brothers revolver. While this might not quite pertain to the OP's interest, I believe it to be pertinent to the question. His method of "hiding" the 4th screw is interesting.

It might not apply to the OP's situation, but I believe it worth a look. Please look through the entire thread.

sourdough,

I read your friends thread in the other forum and it is an excellent idea to just disguise the two shoulder stock screws in the frame. Carefully interrupt a thread on each shoulder stock screw with a small diameter punch. Test the screws in the frame for tightness. Re-interrupt the screw thread if necessary such that the screws are tight sufficiently in the frame to prevent movement. Carefully grind off the screw heads flush to the frame with a Dremel tool, polish and blue. The two grind spots on the frame would result in a hardly perceptible grove ring on the frame if the job is patiently done.
