Davis 22mag problems

[Dirtebiker]

Davis o/u (Derringer style)
Two problems
1. Lower barrel fires, upper barrel does not.
Upper firing pin puts hell of a dent in the rim, but doesn't fire!?
2. I took the retainer and pin out, to investigate, retainer came out fine, but when I tried to put it back together, looks like threads in frame that retainer screws in to are very slightly boogered up, retainer won't screw in ( I don't want to force it and make it worse).

Is there a kind of tap that will fit in there to clean the threads up? Threaded area is only about 3/16" deep, so it would take some kind of a "flat headed " tap to fit .

Thanks in advance for any help.

1. Are the firing pins the same size and type?
Can you swap them and test after you get it back together?

2. Don't know about that one.

1. They look the same. I'm sure they are.

DAVIS aren't quality guns

What's your point? I've got another, 22lr ... Works fine. I can hit a target with them at 7 yds. That's good enough for me! Nice pocket guns actually!

A re-threader of the appropriate size should clean up the threads. I carry them on my tool truck. I am sure NAPA carrys them too. It is just a couple of bucks.

Your problem is not uncommon with the davis derringer. I have one in 22 LR and it still works. If it ever stops working, it will get pitched into the nearest lake.

My point is DAVIS guns weren't made to be daily shooters

Can't be like a regular tap though, has to be only as long as the hole is deep!

O.k., I understand now! As long as I only shoot them every other day, they'll be good to go?!

Bottoming tap, it's called. Bear in mind a tap will only remove material, so depending what you mean by "boogered" it could get loose. It's probably pretty small, too, right? But yeah, you didn't have to go much past "Davis" in your description it's one of the Raven/Jennings/Lorcin/Jimenez/etc/etc group.

I understand it's not a top quality firearm guys, just trying to get to operate properly!
Thanks for the name.... bottoming tap, that's what I'll look for.
Next problem is figuring out why the top won't fire.... Puts a good dent in the rim, and the same cartridge will fire when loaded in the bottom barrel. What else could be going on here?

 

[sloughfoot]

With all due respect, a bottoming tap is overkill for what you need to do.

I am a tool man. I make my living selling tools. A cheap re-threader is all that is needed. When you pay your 1.49 for one, you will see that I am right.

Good luck anyway.

Sloughfoot, I'll see what I can find. Thanks

How many rounds did you try to fire? The reason i ask is i had a few rounds that wouldn't fire on the first try, but did on the second try in the same gun. If it's denting the case real good, i would say it might be the ammo.

You are right. But also, it might be time to throw it into the nearest lake.

As I said earlier, the round will fire when loaded in the lower barrel. I tried firing the same round 2 or 3 times in the upper, then move to the lower, and it fires!

If it is not loaded looking at the chamber is it dented where the firing pin would hit the case?

I have a DM22 also and my pins do not extend the same either, but mine still fires both barrels. It has less than 50 rounds through it.

Top 1/8 inch

Bottom 1/16 inch

Cock the hammer again and see if that changes!

I cocked the hammer and pulled the trigger before each photo to extend the pin being shown.
