A couple years ago I picked up a Hi Point 995 9mm carbine in a trade. Mine is a first-gen model in the ATI stock which copies the look of a Beretta CX4 Storm. The 995 is generally regarded as an inexpensive but reliable gun (unlike the pistols). However, like even expensive guns, they sometimes break.
The last time I had the Hi Point out the trigger failed to reset after a shot. To see what was wrong I cleared the gun, and when I removed the magazine a small piece of plastic dropped out. It was obvious that something had broken but the 995 isn't designed for easy field stripping, so I put it away. Later that week I had some time to take it out to my shop, and found that the trigger itself had broken around its pivot pin. Here's a pic of the action before I removed the trigger and sear cam.
Here's where the trigger broke.
The trigger has a slot molded into the back of it. There's a small coil spring that provides pressure on the sear cam when it's assembled. It was difficult to get a clear shot of this.
I figured that I'd make a replacement for the original plastic trigger out of aluminum, but when I went into my scrap box I found a piece of brass that was the right thickness and only a little too wide. I painted one end with Dykem layout fluid and after it dried, I traced the outline of the original trigger with a scribe.
I left extra material on the bottom to provide something to hold onto while I finish the trigger. I shaped it to this point with a hacksaw, file, and my Dremel tool with a sanding drum. 360 brass machines easily.
After getting the outline done the next step was to replicate the holes in the original trigger. The three large holes are 0.110" in diameter for which I used a 7/64" bit, and the holes for the sear cam pin and pivot pin are 0.06", for which. I used a #53 drill.
The next step is to make the slot in the back face. I did drill some pilot holes but decided that I really need a proper 1/16" end mill that can cut the slot up to 0.3125" deep. So, I ordered a couple cheap ones on eBay and had to wait to finish the trigger until I received them.
