Trigger Stop Rod - N Frame

Fullmetaljacket · Feb 13, 2022

I recently bought a Heavy Duty Transitional variation, c. 1949 production as best I can tell. Upon disassembly for a good cleaning and look-see I noticed the rod missing from the rebound slide. The rod fits inside the rebound slide spring. The Kuhnhausen manual calls it the trigger stop rod and states it is unique to the N frame. Function was fine before I tore it down and even better now that it's all cleaned up. Do I need to search for a trigger stop rod or just ignore it?

I'd imagine they were not standard in a service pistol such as a HD. Pistol will function fine without it. Such rods should be fitted to the gun if used. I've made them before from #100 jobber length drill bit shanks. Both ends carefully polished after cut to length. Will also work on K/L frames. I would NOT recommend these or any other trigger stop mechanism for a duty or carry gun.

Thanks for the reply. What is the function of the rod?

Rod stops the rearward travel of the trigger. If fitted well, trigger will have minimal overtravel. Must have a little overtravel for action to function; zero overtravel won't do. Rod does the same thing as the wedge behind the trigger found on K-frame target guns back in the day. The wedges used to also be there as late as the early 1970's on duty/carry models however factory started deleting them because they could come loose and tie up the gun. Some in the field were removed by department armorers when the potential for a problem became known.

OK, makes sense to find it on a target model which this HD most certainly isn't. I'll shoot it and forget about it. Thanks again for the explanation.

My Model 28 had one(bought new in 1968), so service guns did have them, it was way to short to work as a trigger stop, just for show I guess.

If you want to use one as an actual trigger stop, you will have to get a longer pin and work it down. The factory ones are always way too short to do anything. They are very finicky to fit, you have to get it within a couple thou. of perfect to work well. I have found that with a lot of use, it can bend the vertical pin in the frame that holds the rebound spring in.

In real life, the trigger stop makes little to no difference unless you are a seasoned target shooter competing for the gold - lol. I have Revolvers with them and without and truly couldn't care less if it's there or not! I also have some models with the screw-in style trigger stops - again, no major difference to me.

One can either purchase or easily just make one from a piece of drill rod if you really want one.

IMHO any Revolver used for SD/HD shouldn't really have it anyway - just another piece to potentially stick or jam.
