I have the GI Springer and am looking to improve the trigger a little. It is very crisp, but very hard.
I've been told to change the mainspring housing/spring because the ILS uses a short stiff spring. I'd do if I can find a matching housing: checkered, parked, and lanyard loop. Where can I find one that matches? Any other recs to improve the pull? |
| I have a Mil-Spec which had an 8 1/4 lb pull right out of the box. SA "fixed it" by replacing the sear, disconnector, and sear spring––at least that's what theyr work sheet said. Those changes and proper tuning by SA brought the pull down to 5 lb 1 oz. The "spec" trigger pull for G.I./Mil-Spec is 5-6 lb. If your's is significantly higher than that, you might let SA take a crack at it under warranty. I believe that the G.I. and Mil-Spec share the same parts and both are normally built and assembled in Brazil. |

Smith and alexander makes a mainspring housing that has the military style lanyard loop, but it ain't cheap.
You may be able to find a used surplus one for $20-25. Other things you can do is bend the right finger of the sear spring back just a bit. You can polish the trigger tracks in side the frame along withthe trigger bow, to smooth things up a bit. you can get a sear jig and follow the instructions on squaring, and releiving the sear angle a bit. Shorten the hammers sear engagment notch to .020 inch being careful to keep it square, and polish the sear engagement surfaces lightly. Also, polishing the sides of the sear may make it glide more smoothly within the frame. The disconnector blade that rides on the rear of the trigger bow can be polished smooth, as can the rear surface of the trigger bow itself. You just need to be carefull not to remove too much metal and don't change any angles that you aren't supposed to. |
Dare I once again swim against the arfcom tide? 
As one who strips down his 1911 at the drop of a hat, *I* would NEVER think about tweaking this or that to get a better trigger pull myself. Find $60 or so somewhere & have a gunsmith do a trigger job for you that is both safe & reliable. My .o2 |
