45 Colt BH Three Screw

I recently bought my grail gun. A 4 5/8 45 Colt Blackhawk 3 screw. Last year a few showed up on GB and I bid on a couple, but couldn't stay in the race. I resigned myself sometime in September that I wouldn't find one in my price range. About the same time I had a conversation with my LGS owner about my quest.

Fast forward to a few weeks ago, my LGS owner informed me of a new arrival in his shop. We made a deal and I took home a new to me BH three screw. It is good to be friendly with the LGS owner.

I'm in the middle of disassembly to give it a deep cleaning and discovered something I don't know what to make of it. I have my suspicions. The ejector housing screw hole in the barrel has a threaded insert type bushing, rather than just having a threaded hole.

Either a repair or a chopped barrel is my guess. LGS owner is unaware and I have no intention of making it an issue. RBH's aren't his thing and I've educated him as much as my ignorant self has been able to about 3 screws.

The gun is in good shape and is of shooter quality, not safe queen quality. I will still shoot the heck out of it.

Oh, and no transfer bar conversion!

Congratulations on a very nice find.

Nothing is wrong. I haven't had them all apart, but at least some of my older ones have that threaded insert you describe. I can't tell you if all the three screws are that way.

Someone else will jump in and tell you when they changed over.

Frontiersman is correct, I have a couple of them and that's the way they were done with the treaded insert.

And the threaded inserts sometimes separate from the barrel when the gun is fired. That's why Ruger stopped doing it that way. They can be repaired, assuming that you find the insert. Ruger will probably replace the barrel with a New Model barrel, if you return the gun to them - if this happens. It's certainly not guaranteed to fail. Just a distinct possibility.

Awards Showcase

FlyingFinn, OM 45 Colt Blackhawks were only made for a few years .. 13,200 in 1971, 8,602 in 1972, and just 1227 in 1973 for a total of 23031. They were only available in two barrel lengths, 4 5/8" and 7 1/2", with the bulk being 7 1/2". A handful were made in 4 5/8" Convertibles.

A few years ago, I was fortunate enough to meet an aging gentleman that had a large collection of unfired Ruger OMs. I ended up buying a 4 5/8" 45 Colt Blackhawk and a 4 5/8" 45 Convertible Blackhawk, both in unfired condition. Sadly, the man passed away soon after I bought them.

Here's my 45 Colt BH made in 1971:


and my 4 5/8" 45 Convertible made in 1972:


BTW, all my OMs have the threaded insert that secures the ejector housing.

Nice ones Iowegan. Those were the quality that were waaayyyy out of reach in terms of value last year for me. Then again I was looking for shooters not safe queens.

I'm disassembling mine for a good deep cleaning. Getting the grime off the screw heads, reconditioning the grips with my own secret recipie, etc. In the end I will be proud to own another of the best built single actions. It may not look like new in the box, with the box. But I will shoot it. A lot.

I wasn't even looking for another shooter 3 screw BH. I was picking up the frame I ordered for my 1911 build when this one presented itself.

Funny thing, I walked in the gun shop front door and with a store full of customers the LGS owner shouted across the room "I was going to call you later today, I got something in the back room to show you! Come on back." I felt like gun store royalty. I was given access to "the back room".

Amidst a large estate acquisition were 2 three screw Blackhawks. One a 6 1/2" 357 and the other gave me pause as I saw the short barrel. My vision tunneled. My hands trembled as I turned the revolver over in my hands. Trumpets bellowed. A colosseum sized crowd cheered. The heavens parted and the angels sang. There on the side of the frame it read "45 Caliber". The LGS owner said with a smile of approval "you like it? It'll take a couple of days to get all these logged in, I'll call you when I'm done, give me an offer then." We finished by perusing his newly acquired firearms and he spoke of the tragedy of a lost brother and of all the guns that did not make it to the back room.

Several days later I returned to my LGS. I listened to the distinct sharp four clicks of the hammer. I removed the cylinder for inspection. Sure it had been fired, that was obvious. It had also seen a holster. But the signs of a maintained firearm met my eye of approval. I told him what this level of quality was selling for on GB months before. I made an offer that I thought was a great deal for me and would probably be a good margin for the LGS. The LGS owner said, almost knowingly I believe now in retrospect, making me a returning customer in the future for sure "It's yours. Enjoy!"

Take care all.

Detail strip and clean performed. Internals are in great shape and looks to be well kept. Loading gate plunger, spring, plug screw were a little crusty. I imagine a lot of BH's are like this, as a regular cleaning/oiling job would not do much due to the design of the frame.

I'll post a better picture when I put my 45 Caliber three screw back together.

Cleaned up well. The loading gate "hole" in the frame sure was crusty. Lots of fun to clean (sarcasm).
