Anyone know where I might find a vent screw for a 1970's 50cal. CVA sidelock? Mine has finally gotten rounded up enough so I can no longer turn it with a screw driver.

Have you tried contacting CVA? If not, perhaps your local gunsmith might have the screws you require.

I am not exactly sure what screw you are talking about, but I am guessing it is the clean-out screw in the side of the bolster. I have replaced all of my screws with screws with a allen wrench head in them. They are much easier to get out with a snug allen wrench than a flatblade screw driver. I just went down to the local hardware store and puchased the screws - mine were 6x48 and I am thinking that yours might be a 10x32 - I do not have a CVA sidelock any longer so I can not even check for you. If you can get your current screw out takeit the the Hdwe. store and match it up with a hardened cap screw. Just a thought

sabotloader,
Wouldn't the clean out holethreads be metric on a CVA and the type of allen screw your talking about is an allen set screw....not a cap screw?

I beleive you are right on both counts....

sabotloader,
You're to easy on me I only have 1 CVA side hammer w/the clean out hole. I don't have thread gages at home to check, but I suppose I could take it to work....the screw that is, not the gun. You'd be reading about me in the papers otherwise[]

The vent screw is the bolster end/clean out screw. I was also thinking of going with something other than a slotted screw head. It probably is metric since the nipple is metric. I'll head to the hardware store and hope for a matching allen wrench set screw.

Thanks!
