Default K frame factory adjustable trigger stop

Hi I had a couple of K frames with the trigger stop, itís my understanding these werenít very popular and were often removed especially in defensive pistols. The literature with my 66 mentions itís there and that you can adjust them...but not how. Iím not really looking to fiddle with them but if I were how would I go about that?

These inserts sit in a slot behind the trigger and, after adjustment, are secured in the frame with a screw. The screw threads into the body of the stop itself, not the gun frame. Early ones were shaped sort of like a football, with the screw hole off center, and were prone to coming loose and interfering with the trigger's movement rearward. Because of this, they were often removed by armorers to prevent this from happening, particularly in duty guns.

Interestingly, the screw used to secure the stops is the flat-head screw used in the tang of the old rear sight assemblies. I have accumulated a slew of them over the years.

I'm going to try to stay in my lane here. If you remove the side-plate of the revolver, you will see that the trigger stop is held in place with a small screw. The stop is not perfectly round. By loosening the screw and rotating the stop it is possible to have the rear of the trigger contact the forward-most portion of the stop at a point where the trigger "breaks" but travels beyond that point very little.

You are correct as relates to removal of this stop. Back when dinosaurs roamed the earth and police officers carried revolvers, I recall reading in law enforcement periodicals of the time that some agencies opted to take delivery without this stop or had armorers remove same fearing that the stop might become loose and prohibit full rearward trigger travel with attendant inability to fire the weapon. To be fair, I never heard of this happening but it nonetheless was a concern.

Someone more well versed in this subject will be along shortly to add to this.

HTH.

My M 19-3 came with a trigger stop. I had it back to the Springfield Service Center not long after (back when officers could bring Smith's in and drop them off for service) and the gunsmith removed it. As a matter of policy they removed them from LEO guns because they could shift and keep the gun from firing.

The part itself is a simple tab held in with a single screw and is adjusted by trial and error. It only functions in single action firing (thumb cocked) and has to just touch the revolver frame just as the sear releases... which may be different for each charge hole. In that time period, it went from standard equipment to optional.

It's more likely to cause you trouble. If you decide to shoot a single action course of fire as a Master class shooter... maybe PPC... you'll want a custom gun, with a perfect ratchet, and a screw adjustable stop.

Thank you for the info gentleman. I just thought it was interesting that they seemed to be a feature that they mentioned in marketing for awhile and then seems to disappear. I’m no competition shooter was just curious.
