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.

The set screw its not set and turns very easily while stoning. I took the set screw out and layed it on it's side and tapped on it with a hammer to slightly flatten the threads. Now it's still adjustable but stays where you set it and don't have to wait for loctite to dry. I added a feeler gauge under the one included to remove just enough from the sear for a good surface in case I needed to change the angle and try again I wouldn't need a new sear. A diagram of the sear in the jig would have been a welcome addition to the instructions. It's not the best tool for the job but it is a good value and does what it needs to.

I ordered this tool because I had a customer needing a new sear installed - and at the time unfortunately, I was on a very tight budget.. I was stuck between this tool and the Ed Brown version - but had previously outstanding experiences using products the Brownell's puts their name on...
The instructions included with tool are... well, "Vague" is a gross understatement! After sticking a sear in it from every conceivable angle, you'll eventually figure out how to obtain the proper stoning surface... Also, the set screw, supposed to be factory set at .074", is NOT set... Good luck trying to properly set this, I just happened to have a .075" feeler gauge that I managed to fit in there and set and lock the screw. Also, this tool doesn't have a setting for stoning the relief angle, it tells you to do it by hand and eyeball.
I promptly acquired a Marvell 1911 sear fitting jig, which has slots for both angles, and works wonderfully.
This is the first Brownell's brand product that I have purchased (and I have bought a LOT) that wasn't worth keeping.

The Brownells 1911 sear jig is hard to set up the adjustment screw to .074 inches. There is no LocTite on the screw and it is hard to get a good messurement. It is also hard to use because of how deep you have to reach into the jig to hold the sear in place. The large .020 inch shim is large and hard to hold in place when stoning the Sear.

This was very hard to set up from the set screw adjustment. To holding the sear in place when stoningg it. I should of just ordered the Ed Brown.
It is difficult to use. They did not take the time to set the adjutmant screw

My wife gave me this jig as a Christmas present. Thank you Honey!

By carefully following the instructions I was able to virtually eliminate the creep in the trigger on my first try. I thought surely I would ruin a few sears in the process due to no experience at all. Using this jig and by following the directions I was able to successfully do a triger job right the first time. The overall feel of the trigger after stoning and polishing is smooth, light and crisp. Study the process, take your time and work patiently and you will be rewarded by excellent results.

If you are only woking on one pistol and don't plan on doing any other than this would be the way to go, however if you are going to be doing customer guns then spend the money on a Power Custom jig.

I used this great product for a new sear install on my 1911 and it seemed to work great and I love the result.
Be aware though that this doesn't come with a sear pin, I think it should, so you'll need to order one, have a spare on-hand, or use the one out of your pistol.

Be forewarned that the jig does not come with a sear pin so you'll need to order one, or take one of your pistols and use that one. It would be nice if it came with a pin.

Four stars only for the pin not being included.

Overall great product, works quite well for the novice like me that watched a video and said "I can do that!".

I used it on a new EGW sear and I like the results, also put a secondary angle on that sear. My trigger feels great doesn't reduce the pull weight but the trigger breaks nicely now without a long pull.

This works fine as long as you can set the set screw and add locktite mine was not set and didnt have loctite on the set screw

I bought this tool while waiting on a more expensive jig. I thought I would give it a try. Wow, was I surprised. I followed the directions in the package and it allowed me to cut my sear to the exact angles I needed.

While I'm waiting on the back ordered tool, this new one maybe my primary sear jig.
