I would like to see a picture of the Trigger stop and screw. I understand it goes in the Trigger rebound spring. I own several Smiths and none of them have Trigger stop. I ordered some parts today SW and they had the screw, but not the Trigger stop. Please enlighten me. Thanks Sam

Ok, just to resolve your confusion a bit, there have been 2 types of trigger stops employed on S&W revolvers.

The first type was a tab that mounted in the recess for the trigger and was positioned and held with a small screw. Unfortunately, the screw tended to shoot loose and the trigger stop either didn't function as a stop anymore or it got out of position and jammed the trigger. That type of trigger stop has now been completely eliminated from S&W revolvers but can be found on some of the older Target models.

The second type of trigger stop is what is now used on most of the N frames and some of the Performance Center L frames. This is a small pin that fits inside the rebound spring and blocks the motion of the rebound slide, thus functioning as a trigger stop because the trigger is directly linked to the rebound slide. Now, one thing that I believe is a side benefit to this new type of trigger stop is that it helps to keep the rebound spring from "buckling" and binding in the bore of the rebound slide. I say this because every single N frame I've handled has the least stagy trigger of any S&W I've ever pulled the trigger on. Currently, I have 3 of these stop rods and intend to put them into both of my K frames and my L frame 620. Which have all been tuned but are still just a tick stagy when compared to my N frame 610. IF those stop rods take that last remaining bit of staginess out of the K and L frame triggers it will confirm my hunch.

Now one warning about installing these stop rods is that you have to install them correctly. One end is flat and the other slightly pointed. Unfortunately, I cannot remember which way is correct but I do know that if you install it backwards it will cause the trigger to lock up depending on whether the barrel is pointed up or down. I "think" the pointed end goes towards the pin for the rebound slide but am not the least bit certain of that. Since I have a new 625JM coming I'll be doing an action job on it this weekend and this time I'll actually write down which way it goes when I pull the rebound slide. If nobody else posts the correct orientation check back Sunday and I'll have posted the correct orientation.
 
Smith trigger stop

I have used a sear pin from any 1911 style pistol. The diameter is about perfect and only a little trimming is needed. Trim from the end with the tapered head as this will slip into the spring with use and start to bind up the action. A little longer pin will make your action DAO without permanent changes to the hammer, and a little shorter will make for a good SA target stop. I find most of the factory stops have been fitted too small for any practical use. A tapered pin from the H/W store will also work as will the shaft left over from the the cratex polishing cones from your roto tool (just a little smaller diameter than ideal gut great to practice with if needed

The fitted pin inside the rebound slide spring will work fine in K and L frames too. They can also be made from the smooth shank portion of drill bits. Takes a bit of try and fit to get them just right. The DA function will return first, as the pin is shortened. When the SA fully engages and just functions, its time to stop shortening.

The pin needs to be deburred on the ends, as well as slightly rounded.

It might be possible to get the SA unsafe if the fit is too close; make sure the hammer and trigger fully engage.
 
If your gun is an older K frame with a slot in the frame behind the trigger, I have the small flat trigger stop that is held in there by the small screw, which by the way, is the same screw used to hold down the front portion of the adjustable rear sight.

I like them and use them, but I also use blue locktite on the screw so it will not come loose from shooting. DO NOT use this type of stop if the gun is for duty use or protection, unless you are extremely confident that it will not come loose and keep the trigger functioning correctly.
