I have been working on refinishing a 24 for a friend. It turned out to be a very beautiful looking gun. Refinished the wood, hot blued the barrels, Color case hardened the frame to a wonderful finish. Cleaned and reassembled the and when I test fired it for the first time both the 22 and the 410 went off. It has a side selector switch. It seemed to go back together quite nicely, and I did not even have many parts left over  Any idea what would cause the problem? Thanks for the help Security isa Myth! |

Sounds like the transfer bar has an issue somewhere. How was it set when both fired? Up or down?

It was set in the up position. The side button has the screw. I made sure it was in the threaded hole on the bar. When the screw and button are out the bar moves freely and moves greater distance vertically than when the button is in. My first thought was that there was an issue with it as well. I checked with the guy who owns it and t belonged to his grandfather. He does not know if it did this prior to my working on it.
My thought is that the bar needs to be stretched a bit. I am thinking about using the side of a good size punch and indenting it in a few places along the arm to give it a bit of length. I am just not sure a a few thousands is going to be enough. I guess my next question is if this issue is something that is common to the 24's?
Thanks again

I have a M24 also, in 22 mag over 410. It has had the same problem since purchased new. Many times the hitting double cushions the hammer just enough to cause the 22 mag not to fire. You can see a little dimple on the 410 primer when you fire the rifle. Don't know the cause but am REALLY looking forward to hearing the fix.

I've had the issue on mine since....1958. So far the solution has eluded me.  I kind-of-resolved the problem by not loading a 410 shell until I need it....yeah, that pretty much negates the quick-caliber change idea, but what cha' gonna do?  |

What cha' gonna do? Well, fix it! Decided to dig into it and determine what was wrong. I used the patent drawings to get a good idea of what to look for and many thanks for posting them. I got my 24 in 1960 and apparently it was not assembled correctly when built. The transfer bar did not go up enough to only strike the the 22 Mag firing pin, it was low enough to allow hitting the shotgun pin as well. Got tired of waiting for 53 years so fixed it myself. I opened the slot in the frame upward a bit so the button goes higher. This did not remove all the shotgun pin movement when firing the rifle barrel so I took the transfer bar out and removed material from the bottom of the lug the strikes the firing pins, very carefully. It still touches the shotgun pin but does not make it protrude from the breach face when firing the rifle. Now the rifle pin protrudes correctly when fired and the shotgun pin should no longer cushion the strike on the rifle pin. I would only recommend anyone attempt this if you are an advanced hobby gunsmith or you don't mind taking a chance on messing something up. Otherwise take it to a gunsmith. I am really looking forward to using the little over/under again because since 1960 I pretty much just used it as a single shot .410. Way back then, 22 Mag ammo was so much more expensive than 22 LR that I could not afford to shoot it anyway. I am pretty sure that in 53 years there has been less than 3 full boxes of 22WMR fired through the gun.

rgates that is what needs to be done. Something made it through the quality control that day that the original poster's gun was made. Have seen it a few times, but basically the transfer bar transfers the blow to both pins at once. Not very common problem, but as they say sometimes feces occurs!

jeff, apparently the same quality control system was in effect in 1958 when I bought mine (or maybe it was produced in 1957....I still haven't figured out the date stamp).
rgates, you've now shamed me into fixing mine.....after 55 years....I'll start work on it tomorrow......

I created a video of the fix that I came up with. It is a little different that the one rgates came up with, but it seems to work.
Please excuse my calling the transfer bar a 'Hand" I could not seem to stop.
Here is the link:

Myth, you are a brave soul stretching that transfer bar. Basically you did the same thing I did, getting the transfer bar up higher and taking off a little of the bottom that contacted the 410 pin. Both ways seem to work. Nice video, and I would mention again -- if you are not confident in your ability to work on any firearm, please take it to a qualified gunsmith. It is easy to make your gun dangerous or not work at all. This has been an enjoyable and productive project. For me it is like getting a whole new gun and there isn't anything wrong with that!

I took a number of measurements that I did not put on the vid and felt that there was ample metal on the Transfer Bar for it to work safely. Additionally, the nipple on the part that strikes the firing pin was misshaped as it Had been hitting the bottom firing pin so I just cleaned that up.
I appreciate the help and advise from the forum and one of my favorite all time quotes is from Clint Eastwood..."A man has got to know his limitations"--- I know what I don't know and will always error on the side of caution when it comes to firearms or other deadly weapons.

Another wrinkle to the problem, and another reason to fix it...
You have a firearm that fires more than one round from a single pull of the trigger. Technically that's the definition of a machine gun, and in this case obviously an illegal one. Something that could make your life very very complicated under the right/wrong circumstances. Unlikely, probably. Impossible, far from it.

Any idea what would cause the problem?
