.22 Magnum Pistol Finished!


With my back on the fritz I’m stuck doing light-work so I decided to finish this project today. Didn’t get pictures of the process this time unfortunately.

First step- the raised block at the front of the barrel has become ‘ears’ for the front-sight. I mounted the barrel in the milling-vise on the drill-press. Using a 3/8-inch end-mill I carefully removed the material from the center to a depth of about .100 inches. Since the drill-press is a seriously crappy milling machine I carefully filed it to finish. I used a .062″ drill to make a hole centered between the ears and mounted a piece of .062-inch music-wire for a front-sight and trimmed it to height.

That finished I attacked the rear sight. First I milled and filed a groove at the top-rear of the barrel with a 3/16-inch end-mill. Again this was sloppy as hell, so I squared it up with files, then undercut it with a cutting-wheel in the flex-shaft tool, then filed it to shape with a triangular file.

I grabbed a piece of 1/2-inch mild steel, measured the sight-slot and sliced off an appropriately-sized piece. I carefully ground it to match the slot. Since the slot is very slightly tapered I tapped the sight into place with a drift until it is roughly centered. This is a serious force-fit; pretty sure it’s not going anywhere. Mounting the barrel on the drill-press again I mounted the 3/8-inch end-mill and undercut the back of the sight to produce a vertical surface, then used a cutting-wheel and files to cut the rear-sight aperture.

I refinished the gun by the simple expedient of immersing all of the external parts in Van’s Instant Blue for 3-4 minutes, then thoroughly hosing everything down with WD40 and rubbing off excess oxidation with paper towels. The reassembled gun has a lovely charcoal-gray finish that is rather darker than the pictures show.

This is not at all a large gun- the frame is only 1/2-inch thick, and the barrel is just a slosh wider. The fore-grip is the widest part of the pistol at around 7/8-inch wide. The barrel is 4-1/4 inches. If I remember correctly the gun weighs about 19 ounces. The trigger-pull is light and pleasant and the gun points to a sight-picture naturally. The gun balances on my trigger-finger, and the grip fits my hand extremely well. Hardly surprising since I made it for me…

Quite happy with how this has come out. The only thing left is to polish the chamber a bit. I’ll make a field holster for it; it would make a useful companion for hunting or the like.
