USrifle brought in a Springfield Armory Range Officer for his Black Hammer Arms trigger job that he won here on WAGUNS. The trigger had a steady pull and break weight of 4.5lbs that felt like Gaston Glock and John Moses Browning had a love child and called it Mashed Potatoes.
What’s the first step in doing a trigger job? Cleaning the gun.
I don’t know who did John wrong but, the last FFL to have this gun had to reassemble it for him and according to him, he didn’t take it to them like that. The gun needs some spa time.
Starting with a bath in acetone.
It looks like someone skeet skeeted all over the parts and put it back together. Ewwwwww. So after that soak and scrub, everything gets a bath in Slip 2K to keep an potential rusty away. I let them soak over night. The frame and slide were cleaned by hand and not soaked in acetone.
Excess is wiped away and the gun is reassembled. The trigger pull and break increased by a half pound. Imagine that! But now it’s a much more crisp break. On to the trigger job.
Now..who does this? We want polished parts! Not poorly machined and parkerized...SA...I expect more out of you guys.
You can see that as soon as I start to stone the face, the high areas show up.
The face gets stoned until it’s completely polished, hammer hooks are the proper height and the sharp edges are slightly broken. Here’s some polishing after stoning.

The sear...the sear has one angle and the another edge that was showing the sear was not properly prepped. It was prepped and polished with stones. I’m a bit bad sometimes with taking pictures and I didn’t take pictures of those parts.
Other parts to this trigger job are polishing mainspring housing tunnel and the stems of the internals rubbing the spring, polishing areas of the sear spring, polishing the flats of the hammer and sear to decrease friction, polishing the trigger bow. Do your parts shine like this?
The trigger pull weight and break weight are set in the the sear spring. I like to have a pull weight of no more than 1lb and the break weight is set to 4lbs. But what else is going on? The thumb safety was fitted by someone else but, they missed a detail. It’s rubbing on the plunger tube. Let’s address that by filing in the right area and touching up the tube with cold blue.
Someone really should pay attention to these things.
Do your mags drop free under stress? Are you sure about that? See this video about addressing that.

You need relief in your magazine release.
You can see the relieved area has been touched up with cold blue.
The barrel ramp and throat were polished as well just like I did his Ruger. Didn’t take pictures of that.
A properly worked 1911 is a thing of Beauty. Polymer frame guns with strikers have no Soul.
