Trigger Pull Worlds Largest Supplier of Gun Parts, Gunsmith Tools Shooting Accessoriesby Jack Weigand. Early in my career as a pistolsmith, I worked hard to develop a process I could apply to all 1. Auto Pistols that would produce a reliable 2 pound trigger pull that broke clean and would not follow. After a lot of trial and error and experimentation, I came up with the following process that has served me very well over the years. Its the same process I now use during the Trigger Work portion of the NRA 1. Auto Accurizing class that I teach each May at Montgomery Community College in Troy, North Carolina. It seemed many of my customers that shot in the U. S. P. S. A. sanctioned matches wanted a very light trigger pull, usually around 2 pounds. Using this method you can get trigger pulls that are lighter than 2 pounds, but very few shooters really know how to properly use a trigger pull that light and I think it can get them into trouble. Bow Wow The Price Of Fame Zip here. Handguns that I build for carry, duty or defensive work have a 4 to 4 pound pull weight. What is most important with any trigger job is that you have a minimum of takeup, very little creep, so it breaks clean and no overtravel. Using the methods Ive outlined here, you will be able to consistently produce trigger jobs that meet all those requirements. One word about tools and replacement parts. Ive included all of the tools that I use in my shop, but not the names of the individual components that I use. Other tools are available that are designed to do the same job and custom, replacement parts are very plentiful. Whichever tools you use, be sure to buy professional quality tools and dont waste your money on bargain basement or inferior parts. You cant guarantee your work if you use cheap parts. And, never experiment with your customers parts. Professional quality tools and parts will provide the results youre looking for with a minimum of hassle.

It is very well made, fully adjustable and will last a lifetime. The only part that ever wears out is the roller guide, and it can be replaced for just a couple of dollars. Set the fixture on 2. Norton FF4. 6 Fine India stone 6. Remove the hammer from the fixture and carefully dress the hammer hooks to an exact 9. India stone.

Volquartsen Custom 1022 and Ruger Mk III Accessories Ruger 1022 Barrels and Parts, Custom Mk I, II, III, and 2245Do the final polish on the hammer hooks with a sharp edged Arkansas stone. At this point, closely inspect the hammer strut to see if its been rubbing on the disconnector spring. If you see rub marks on the center leg of the spring, remove material from the strut until it clears the spring. DISCONNECTOR PREP I lightly polish the front surface that is touched by the trigger bow and the rear surface that is touched by the disconnector spring to insure free, up and down movement in the frame. The disconnector must move freely, up and down for positive disconnection. I break the very bottom edge of the disconnector with a slight radius to remove any sharp edge I may have made when I polished the two surfaces.

The magazine release button is under my left thumb. Hold it down and pull the magazine from the bottom of the pistol handle. If you look into the magwell opening of a fully assembled 1. Auto with the slide locked back, you can see the next surface that I want to talk about. See figure 1. You will see the leading edge of the disconnector hangs slightly into the magazine well opening at the rear of the frame. When a loaded magazine is inserted into the frame, the edge of the top cartridge can come in contact with that bottom edge of the disconnector. This problem is more common with the large diameter rim on the. ACP cartridge. As we lighten the trigger pull and reduce trigger and sear movement, this contact between the cartridge rim and the disconnector can cause the hammer to fall and the pistol to fire. Remove material from the disconnector as shown in figure 1 to keep this from happening. SEAR PREP Deburr the sides of the sear with a fine India stone. Smooth up the radius on the bottom of the sear legs with the fine India stone. This is the surface that the disconnector rides on when it is pushed down by the slide. Set the Power Fixture on 4 clicks, install the sear on the adapter as shown in the Fixture instructions and cut the primary angle with a fine India stone.

SEAR SPRING PREP The adjustments that I make to the sear spring are the only variables I use to determine final trigger pull weight. The lighter I set the sear spring, the lighter the final pull weight and vice versa. The 1. 91. 1 Auto sear spring is a flat spring that has three legs and it works as a return spring for the sear, disconnect and grip safety. When viewed from the rear, the leg on the left works the sear, the leg in the center works the disconnect and the leg on the right works the grip safety. Install only the trigger, magazine catch, disconnector, disconnector sear pin, sear spring and mainspring housing into your bare frame. Notice that when you pull on the trigger, you are feeling spring tension from the center or disconnector leg of the sear spring. Clamp the frame in your bench vise with the frame rails level with the top edges of the jaws. Use an RCBS Trigger Pull Gauge 7. Adjust the tension of the center leg of the sear spring by bending the spring leaf above the pivot point at the mainspring housing. Bend the spring outward to create less spring pressure, bend it inward to create more spring pressure. Adjust the spring pressure until you get a reading of 8 oz. Pull rearward on the trigger with the Trigger Pull Gauge only enough to cause the disconnector leg to move. If you pull it too far, you will also engage the sear spring leg and that will cause you to get a false reading on the gauge. Next, add in the sear to the limited assembly. Again, measure the spring pressure with the Trigger Pull Gauge. We now need a total of 1. If you get a reading that is either more or less, bend the sear leg of the spring in or out until you get the 1. This is really the only variable I do to my trigger jobs. If I need a heavier weight trigger pull I adjust the tension of these two spring legs upward. Remember, both legs of the sear spring need to be adjusted equally. Here is an example for a 3 pound trigger pull Disconnector Spring Weight 1. Sear Spring Weight 3. The only sear springs that I use are the Colt factory spring or the Wolff. I use the Wolff 1. Mainspring 9. 69 2. If after assembly the trigger seems to have a little creep, I use the old gunsmithing method of boosting. To boost the hammer, cock the hammer just as if you were going to fire the pistol. Apply moderate thumb pressure to the hammer so you are forcing it toward the slide and pull the trigger. If you do this approximately 1. If the creep remains, go through the entire trigger job process again and double check all of the operations to make sure they were all done correctly. Here is a special note about certain problem jobs that can drive you nuts. Some brands of 1. Auto frames are built to different specifications than the Colt. Exterior dimensional changes arent usually a problem, but pin hole locations that are not correct will always cause big headaches.
