Last winter, I got one of my bucket list guns, a early Ruger 44 Carbine...
Attachment 199131
The above pic is an example of how far the cover is left open when it does fail to close. I have become well versed in taking it down and cleaning the gas port, and am at the point now where I can strip it and put it back together in Just a few min with a decent punch and a plastic hammer.. I have cleaned and lubricated it several times... never failed to close when just cycling the action by hand, only after being fired... doesn't matter what sized bullets, jacketed or cast, from 240gr jacketed on... seems to do it occasionally with everything.. in 10 shots it happens once pretty consistently. The cover closes when it does jam with a push from a finger, but it is dang annoying... can't seem to see what is causing it..
Anybody else struggle with this?
Thanks...
