I had been looking at the 460 Rowland conversions for 1911's for a while when a thread on them came up here.

I had one of the unmarked Norinco 1911's from the Canada Ammo deal still sealed in the plastic waiting for a suitable project, and figured it would be a good match. I put the barrel and compensator on without ever firing it and headed to the range.

First mag at 15 yards. I pulled the first shot way low, expecting a lot of recoil, but it wasn't too bad.

After about 225 rounds through it, there was a bit of peening on the barrel lugs, so I figured I better get that fitting better.

There wasn't enough clearance for the barrel in the slide, so I opened it up a bit and cleaned up the barrel lugs. I got it to pass the 1911 timing test as published by Schuemann barrels, so it should be good now. Just have to copy and paste for the PDF article.

I had ordered a few goodies from Brownells for it, so there are going to be some cosmetic changes too. I got a beavertail grip safety, new sights, long trigger, oversize firing pin stop, commander hammer, and a new sear. I also got some files so I can try my hand at some checkering. While I was waiting for the goodies to show up, I decided to make a mag well for it from some scrap steel. I only have hand tools, so it's a bit of work.

A bit of filing and welding and I had a flat mainspring housing with a mag well attached. It still needs some more work, but that can wait until I get the material for the grips.

I also welded up the bottom corners of the frame so the mag well fits better. While I was at it, I cleaned up the relief cuts behind the trigger, and cut the frame tangs for the grip safety.

I prefer an undercut trigger guard, so I knocked that off the list too. The two-tone look is really starting to grow on me, might have to send the frame to be hard chromed when I'm done.

I got the beaver tail fitted ok.

And checkered the front strap. This is the first time I've ever checkered anything, so it's far from perfect, but it is grippy.

Here's what it looks like so far, still lots of work to do yet. I didn't like the big gap between the slide and comp, so I threaded it on a bit further and got it straight too.

Nice project. You are a talented craftsman. The magwell and checkering look awesome.
 
That is nice work! If that's your first checkering job then all I can say is hats off to you. Bit surprised at the
barrel peening though for 4.5 boxes. Did the slide lugs come out ok? Powerful round.
 
nice work Kristian!

i thought i was getting good at messing around with my guns, that front strap checkering job is sweet!
you have to post a little info on how you did it!
 
Thanks guys. Still lots of work to be done on it. I'm pretty sure the barrel lug damage was from lack of clearance in the slide and not linking down soon enough, so the lugs were getting dragged across the harder slide lugs. All the work I've done is real easy, I use a Dremel with the large and medium sandpaper rolls and various files for the rough work and 80, 150, and 220 grit emery cloth for finishing. For the radius at the back of the frame to the beavertail, behind the trigger, and under the trigger guard, I wrap the emery cloth around a socket to get the radius I want. For the radius under the beavertail and for things like truing any round surfaces I use long strips of emery cloth and a back and forth motion after draw filing them. It just takes a bit of time and patience.

For the checkering, I first put a horizontal line at the top of the checkering with a triangle file, the wrapped some copper wire in the groove tightly for an end stop for the checkering file. then I put the frame in the vise with aluminum soft jaws above the front strap surface so I could use the jaw as a guide. After I got the first few lines, it was all freehand. I slipped a few times getting impatient and trying to go too fast, so it's far from a perfect job. Now I know why getting a checkering job done is so expensive, it takes a lot of time. Everything I'm doing can be done by anyone with a bit of patience and some time.

I've done a bit more to it now. I checkered the mainspring housing over the last couple weekends, and it went better than the front strap. It's hard on fingers and elbows though. I also got my grip material in the mail and got started on them yesterday. I slipped while drilling one of the holes and the one grip screw just pulls right through now, so that one is my test piece. The material is called Kirinite, I ordered a piece 12" x 6" x 1/4", so I have enough to cover a couple mistakes. Here's the first one roughed out, pictures don't do the colours justice, the colours really come alive after a quick buff with some fine steel wool.

Here's a couple more pics of my Norc 460. I parkerized the frame and small pieces in a home brew solution on the kitchen stove today (I have a very understanding wife) and assembled the gun. I was hoping for a light gray finish on the frame, mainspring housing, and grip safety, and was going to use a different recipe to get a darker finish on the slide, thumb safety, and slide release, but the recipe that was supposed to be light gray ended up jet black, so I dropped the slide release and thumb safety in too. The frame will get refinished after I mill it for some new sights, but I won't have access to a milling machine for a while, so this is how it will stay until probably sometime this fall. Ive got a fiber optic front and a Bomar adjustable rear from STI to install. I ended up putting the Kirinte grips on a stainless SAM for my wife for her birthday, and she busted me putting them on for the picture, so I guess I'm making another set of them when I have time. The I don't really care for the way the shiny wood grips fit in my hand, but they look nice, so they will do for now. The parkerized finish is more even than the pictures show, as well as quite a bit darker. There are a couple spots where I did some welding that the finish isn't real even, but I kind of expected that.

Does anyone know if there are sig mags that fit the np29, if so what model? If not can anyone recommend after market mags? Part number?

Fantastic looking build, you sir are a talented crafts man, those kirinte grips are sharp! I've never owned or shot a norinco but I'd love to give that one a try. Nice job!

While the steel in these is definitely a bit hard, sharp tools cut it pretty good. I know my checkering file is sharp, my thumb took a beating. I figured out to only work on it for an hour or two at a time or else I'd start to get impatient and rush things, and that's no good.
