BROWNELLS - 1911 Sear Fixture

First, you need to use the sear pin that is going to be installed in the gun. That is why there is no sear pin included. Second, If you try to hold the fixture and the .020 shim and the stone, you are working too hard. Use a vise and put just a little oil between the fixture and the shim. The hydraulics will hold it down. I got great results the first time I used this jig. If you understand how this works you will too.

does just what it says it will do.

Just used this tool for a 1911 trigger job. I was able to set the primary sear angle on a RIA .22TCM/9mm 1911 using this tool along with the Brownells 2-stone ceramic file set. One reviewer indicated the set screw in the tool was loose. Mine was not, and was set correctly @ 0.074 (or 0.417 as measured from the end of the tool as Brownells suggests) and the screw seems tight. I had to experiment with how to hold the tool so I could keep pressure on the sear against the set screw with one hand and hold the ceramic stone and shim on the horizontal surface of the tool. Once I figured out the routine, keeping the precise angle was quite easy while stoning the sear nose. Setting the secondary angle was easy as well. Just follow the instructions. Result: 3lbs-15oz trigger pull, no creep, clean break. I found that adjusting the sear spring for fine changes was pretty easy to do, so don't worry if your trigger pull comes in a little too low. Easy to give a little more bend to the sear spring leaves for a heavier pull weight. This is really a great value in another tool from Brownells.

HAVE USED THIS SEAR JIG FOR AT LEAST 25 YEARS & IT HAS NEVER DISAPPOINTED !!! A SEAR PIN IS NOT INCLUDED, BUT....(1) USE THE SEAR PIN FROM YOUR PISTOL (2) USE THE SEAR PIN FROM THE "EXTERNAL HAMMER & SEAR FITTING PIN" KIT (3) SEARCH THROUGH YOUR SMALL PARTS INVENTORY & FIND ONE THAT FITS THE HOLE SNUGLY & DESIGNATE IT FOR THE JIG !!!!!!! THIS ORIGINAL "TOM WILSON" DESIGN WAS NEVER INTENDED TO BE HELD IN YOUR HAND. IT WAS DESIGNED TO BE SECURELY CLAMPED IN THE PADDED JAWS OF YOUR BENCH OR MACHINIST VISE !!!!!! .020" SHIM STOCK WON'T BEHAVE ITSELF ??? PLACE A COUPLE OF DROPS OF NON-HARDENING CLEAR SILICONE CAULK OR CLEAR NAIL POLISH ON THE WORKING SIDE OF THE JIG. PLACE THE SHIM STOCK ON TOP, GENTLY CLAMP IN PLACE, & ALLOW TO SIT ABOUT AN HOUR IN A WARM PLACE. MINE HAS NOT MOVED FROM THE JIG IN THE PAST 15 YEARS---DUH !!!! FINALLY, THIS SEAR JIG IS DESIGNED ONLY FOR THE PURPOSE OF STONING THE "SEAR NOSE PRIMARY ANGLE". IT WAS NEVER INTENDED TO STONE THE "SECONDARY NOSE ANGLE" !!!!! THE COMPLAINTS POSTED IN SOME REVIEWS, ARE TOTALLY UNWARRANTED. SIMPLY USE THE JIG AS IT WAS DESIGNED TO WORK !!! IT IS VERY WELL MADE, DOES WHAT IT IS SUPPOSED TO DO, & WILL BE AROUND LONG AFTER YOU HAVE PASSED ON---SEMPER FI !!!

For the price this stoning fixture worked very well. The screw will have to be checked and adjusted for each different sear. Sears from different manufacturers will be slightly different. Just mark the sear surface, hone lightly with a fine stone and check the angle. Adjust as needed. I did two sears in a short time and had a noticeable improvement in both. The fixture does not have a pin to mount the sear, but this is irrelevant since the sear pin must be removed from the gun anyway. More illustrations on how to set up and use the fixture would be helpful.
