Ok, after performing the sear modification as listed in Sid's Stingray FAQs and Quake's Ultimate Trigger Job, and adjusting it, the sear should release with a fairly snappy pull. The forward trigger throw is also fairly easily adjusted by placing a bolt across the trigger arm. But, I was still not satisfied with the total trigger travel on my Ray. I wanted to get another set screw between the back of the trigger and the front ot the grip. This screw would act as a direct block for rearward trigger travel. There were two problems though, how to drill a hole in the grip frame behind the trigger and how to access the sear adjusting screw with the new set screw crossing its path.
With my mind a-whirring, I had an idea, I grabbed my drill and punched a small pilot hole through the back of my grip, directly behind the trigger. I drilled all the way through to the front of the grip, coming out just behind the trigger. Next, I removed the trigger. I used a small allen wrench and hammer to lightly tap out the pin. Once I got the trigger and trigger spring out, I removed the safety. It was non-functioning after the mods anyway. I picked a 6-32 x 1 1/2 " allen head machine screw. The hole needed a bit of widening and the screw was a little hard to get started from this angle, but it finally took. By using the short side of an allen wrench and pressing very hard, the set screw finally bit. I screwed it in farther than needed. I put the trigger back in and tested it. It shortened the trigger throw, but needed adjustment. I pulled the trigger back to the point where it released the sear (pull the cocking bolt back, pull the trigger to just the point where the gun fires) and noted the position.
An easy way to help screws thread into the plastic is to put a nut on the screw, all the way against the head. Then take a very fine square or triangular jewler's file, and file grooves in the threads on the tip of the screw, and remove the nut. (The nut serves to de-burr the threads after filing.) Voila! You've just manufactured a self-tapping screw! Alternatively, you could use a cut-off wheel in a Dremel to cut the grooves. Might be a little faster.
Adjusting this bad boy is not much fun, but the results are worth it. So, I took the trigger back off and unturned the set screw a few more turns. After doing this two more times, the trigger pull is down to about 1/8". This is the actual, physical distance the trigger can travel. The set screw is very sturdy.
After installing the screw, I have another idea so both it and the set screw can be adjusted, independently with the trigger in place. Instead of machine screws or allen headed machine screws, use machine screws with regular bolt heads. A small wrench could be used to adjust both the screws if needed. This would be slow, but not as slow as taking the trigger out of the grip frame. This idea I haven't tried yet. If someone has the time, let me know how it works out.
Instead of using a headed screw for the rearward trigger stop, you might try this - go ahead and drill all the way through the grip from the back, like above. Then drill the rear hole a little bigger. Thread a headless setscrew through the front of the grip from inside (so that the "top" of the screw is inside the grip and the "bottom" of the screw sticks out behind the trigger). This way, you can adjust it through the grip with a long allen wrench, without disassembling the trigger assembly.
