Wow this is pretty cool....people are actually visiting the site I guess.
Malmon: To answer your questions.
When I polished the trigger bows, I also did the shoe part. I forgot to mention that on the site. As for the shoe, it fit without any modifications in my gun, but what you waould have to do if it didn't is pretty simple. I'll try to explain.
Start by stripping the gun all the way down. Remove the old trigger and insert the new one. Don't bother re-installing the magazine catch button, because chances are you'll need to remove and replace the trigger several times (if it doesn't fit first time). After you get your new trigger in, go ahead and re-install the sear spring (the little finger thingee spring) and the beavertail safety and the thumb safety.
** NOTE ** I don't install any other parts while I'm checking it 'cause they just get in the way anyhow. So you have your frame with nothing but the a.)trigger, b.)searspring, c.)grip safety and d.) thumb safety nothing else installed. You may want to slide the mainsping housing in enough to just hold the sear spring in place (so it dosen't twist all around on you.)
You need the searspring so you can see how it will act upon the grip safety and so it will return the trigger forward for you (without having to push it with your finger). You need the thumb safety so that it will hold the grip safety in place ('cause the thumb safety also acts as the pin for the grip safety you see).
Ok so now you're ready to check it out. Hold the gun in your hand or lay it flat on the table so that you can have a clean view of the back of the trigger shoe (you will need to look into the opening where the magwell is, looking through where the lefthand grip would normally be) If you do this you should be able to see the little notched arm of the grip safety. You may need a small penlight to brighten things up a bit.
Ok, the sear spring is pushing the grip safety into the safe position right now so what you are looking for is to see if the little notched arm is "Blocking" the trigger shoe from moving back. (It should be) so if you try pulling the trigger it should hit the grip safety arm. If it doesn't hit the arm....try to look at why it isn't. In some cases it's because the trigger shoe is too far to the rear...which means that the grip safety arm can't swing in behind it even to stop it when the trigger is all the way forward. If this is the case it usually means that the little arm part of the grip safety is too long. Look at the grip safety real close. You'll see that the arm part I've been talking about is longer on the top and notched on the bottom. You need to file off the top (long part) just a hair until it will swing down in behind your trigger shoe (but just barely). You don'y want to file off so much that it allows the trigger to move rearward, just enough to where it will swing in behind it. This keeps the trigger blocked so it can't move when the grip safety is in the up (not being held) position.
Next you need to make sure that when you depress the grip safety, it swings far enought up that the trigger shoe can now move to the rear. (the bottom part or "notch" of the grip safety arm) Should not be long enough to block the trigger from coming back. If you depress the grip safety and pull the trigger, it should come right on back....if it doesn't you may need to file off a little bit (deepen the notch) so that it allows the trigger to come back.
Really that's all there is to it. As far as the "Bastard" file your friend told you about....well that just refers to the cut. Kinda like grit means to sandpaper. A bastard is a medium grit file basically. I don't want to step on your friends toes or anything...but personally I wouldn't use anything like that. You need to take off fine little bits and go slowly. remember you can't put it back on as easy as you take it off. I would use (Just my opinion) a swiss pattern needle file with "fine" teeth (about a #2) If you use the file I recommend then you could finish up with a popscicle stick wrapped with 400 grit wet/dry sandpaper to smooth everything up a bit.
I appologize for being such a long winded SOB....hope that helps.
Let me know what you decide to do.....Good Luck, and thanks for checking out my site. It's nice to know I'm not just wasting my time.

I guess if we do that.....maybe we all earn the right to go home.
