As you can see from the diagram on the left the holes are drilled using the pre existing cutouts as a guide. No measuring required. I removed my trigger from the gun before drilling the preload adjustment just to reduce any risk of damaging it as replacements are hard to find as of right now. I HIGHLY recommend using a drill press for this, but if you feel comfortable then a hand drill can be used with good results also. Just drill the hole in the first circular cutout in front of the trigger blade as shown in the picture. DOUBLE check the position, looking at all the other pictures in this file before drilling.

The over travel is drilled through the bar underneath the trigger parts. Using the gun as a template mark where the hole should appear according to the picture on the left and then drill. Make sure the part is supported by something underneath (piece of wood etc) because they can bend easily. Also take care when tapping the thread for the same reason.

After the Over Travel Hole has been drilled and tapped showing the Pre Load Screw. The Trigger was removed, the pin sticking out of the bottom of frame is the one used to retain trigger.

Trigger bar showing what it will look like after the Over Travel hole has been drilled and tapped along with the 10-32 set screw above it.

Gun with the Modified trigger bar installed. You can see in the Preload picture above that it matches up with the circular cut out.

As you can see from Air Forces Patent drawing both adjustment screws act on the same part. Over tightening both screws can damage your trigger. Make sure there is SOME movement of the trigger; otherwise you risk not only breaking the trigger, but you will likely have an unsafe trigger. When adjusting the trigger do it WITHOUT a bottle attached to the gun and make small adjustments. Use Loctite or similar to keep the set screws in place.

Adjust one screw at a time. I start with the Over Travel. Keep tightening the screw so that it goes IN until you have limited movement of the trigger after the sear releases. If you go too far then the gun will either hesitate when firing, or won’t fire at all. If that happens then adjust it OUT a small amount.

When adjusting the Pre Load extra care has to be taken as if it is over adjusted the trigger can be in an unsafe position where it is ready to go off with slightest touch. You need SOME first stage to ensure it’s a safe trigger. I don’t recommend nor suggest anyone adjust it to “lighten” the trigger and take up second stage to reduce the weight. Tighten the adjustment so that it goes IN, keep checking by pulling the trigger (No need to cock it) until you have a tiny bit of movement before it gets slightly harder to pull. If over adjusted you will be unable to cock the gun. Adjust it back out until you can cock the gun, and then keep going a small amount to give yourself some first stage.

The finished result should look like my Talon SS on the left and will result in a MUCH improved over stock trigger that doesn’t have a lot of first stage travel and stops right after the gun fires which will improve accuracy a great deal.
