Hello and hope someone can help.
I have an early .44 mag. Ruger carbine. It is in super shape but the slide locked open when I shot it. It wasn't the last round. I managed to get it taken down and freed the slide so it worked. I didn't bend or pry anything.
I pulled the slide open and it locked open again. It will not go shut when I depress the under button. I believe I was using pistol ammo in this older version. Is this repairable by a gunsmith?
I already know the factory no longer has parts per inquiry with Ruger customer service.

I looked up the serial number and mine was manufactured in 1980.
I'll tear it down and look again to see if there are any areas that need to be deburred on the back of the bolt.
thanks for your reply

Thank-you All for your comments...I have discovered the culprit. I looked into the lifter mechanism. What I discovered was the lifter latch has a pin other than the hinge pin that keeps the lifter from moving until you depress the lifter latch to load it or the gun fires.
This pin had slid all the way to one side keeping the lifter from operating (couldn't feed next shell). The gun thought it was in the "last round mode". It appears to be a simple fix if I can tighten the pin in the lifter latch......any suggestions?
