CVA pistol advice

[Old Painless]

I have an old CVA pistol barrel that needs some TLC. The screw that was in the powder drum was mangled and looked bad. I was going to look for a screw but not sure where to look or what to ask for.
The thing I call the “powder drum” that holds the nipple, looks fair. But I was wondering about changing it also. Thanks

Do not attempt to change the drum. The breech on CVAs is very complex and easy to destroy when removing. The screw can be replaced easily if you know the size.

If it is metric get the correct size cap screw. If it is too long also get a nut for it. Put the nut on the screw and shorten the screw to correct length and remove the nut. That way the threads won’t be buggered. Grind off the socket part of the cap screw and file a screwdriver slit and install. If the screw is shiny, fire blue it with a torch or brown it etc. whatever is appropriate. Ace hardware probably has one for less than $1.00.

Deer Creek and TOTW both have CVA bolster screws for $2.00

It is metric isn't it?

I use hex when I replace, easier to get out when FILTHY. Most will damn you for ever removing it cuz they say its not a clean out screw even though many clean it out each cleaning.

Metric on that. I believe all European imports and Asian are. That barrel was made in Spain.

put the old screw back in file it flush with drum and forget about it. there are likely a thousand threads about the " clean out screw" on here. the popcorn is on
