Default Makarov PM Refinish and Barrel Recrown

As some of you may have undoubtedly researched, there are plenty of the refinishing how-to write ups on the internet.
I wanted to add my own story here to help people who are unsure what to do when the buy a second-hand/surplus gun, which was not quite what they expected cosmetically.

Same thing happened with me, as I collect Russian-designed weapons, for a while I wanted to get Makarov PM. Given that Russian Military models are not available at reasonable prices, I decided to settle on second best – Bulgarian military import.

After many attempts and GunBroker bids I secured my weapon, which according to blurry pictures and description should be in an excellent shape with excellent barrel.

After receiving the weapon, it looked like it was either pounded by a hammer on its barrel face, or was dropped on a concrete, muzzle down, from a considerable height. Basically was I exnded up with is a weapon with a seriously damaged crown, front sight, and marred finish on the slide.











My choices to fix the crown are of course – change a barrel altogether, go to a full-service gunsmith to use a lathe or attempt a fix using hand tools. Midway USA’s Larry Potterfield has an excellent how-to video on fixing a damaged crown so I decided to give it a go:

Given the fact that Makarov barrel is about 9.2mm, I could not find an appropriately sized bolt in my local Home Depot, but what I did find was a semi-round Cap Nut which would serve the purpose beautifully (Found in Home Depot), do drive the cap nut on the drill I used a saw to cut a threaded bolt shaft. For the grinding paste I used Valve Grinding Compound (Found in Pep Boys), which is used by mechanics to grind and lap engine valves



There are the pictures of the set-up:





After finishing with the crown job, I moved on to working on the slide, using a Flat File wrapped with 500-grit sandpaper (Use Wet Method with either cutting oil or light gun oil [CLP]). I sanded the slide down on the damaged side, filing front sight in the process to have a uniform sight picture.

(The slide is actually white on right side and part of the top, as all the bluing was sanded down during repair)

Now that I have finished with repairs – it was time to re-blue the slide. I have used (with great results) in the past Brownells Oxpho-Blue (http://www.brownells.com/gunsmith-to...-prod1072.aspx)

There is a great method of using this cold blue described on YouTube by Iraqveteran8888

Please note that steel-wool (which needs to be degreased) is required for a smooth finish, I have used Acetone (Home Depot) to degrease the slide.



After performing the bluing, make sure to wash your parts with warm water and then use WD-40 to eliminate and displace any water leftover.



…. And this finished the write-up for now, please stay tuned for pictures of the final result

That looks great. I use the rust blue but ittakes forever. Yours seems like a higher gloss finish
