Good evening everyone, recently I decided to buy my first revolver and went with a used Ruger 44 mag SBH. I enjoyed the one range trip I got out of it (though am looking to see if I can better grips as the stock grips are a little small to comfortably hold when using magnum rounds) but afterwards I ran into a moderate issue: the base pin keeps falling out of the cylinder and binds up the revolver.

It seems that the latch (?) is able to wiggle from side to side and when it does so the base pin just needs a little bump to slide out. I've seen some other people describe what appear to be similar issues, but from what I could tell there's also a debate over the solution as to whether the fix is getting a Belt Mountain base pin, sending it to Ruger to fix, or filing a part to somehow help the base pin lock in. Because I'm unfamiliar with revolvers I figured it was best to try to describe my problem to be sure I'm looking in the right direction for a solution. Any recommendations appreciated.

The base pin latch can be problematic. Sometimes they come loose, and you'll need to either modify a yard sale screwdriver to fit, or buy a special screwdriver bit to tighten it up. Sometimes an extra strength spring can resolved the issue. Sometimes the base pin can be modified by deepening the slot on it where the latch engages. Many folks replace the factory base pin with an aftermarket product. You really need to do a little more troubleshooting to determine exactly where the problem lies.

Thanks for the quick reply. I've seen the spring idea mentioned before on other forums, though I'm a little unclear on what spring would be replaced because it appears there isn't one involved in this issue.

In terms of further trouble shooting, can you recommend anything in particular to look out for/how best to go about trouble shooting it better?

There's a little spring inside the base pin latch that keeps it "closed". If that spring is broken, missing, or too weak, that would explain why it keeps unlatching under recoil.

You can buy extra strength cross pin springs from Brownells.
You can also buy the special 2-prong screw driver to fit the screw on one side. There is a spring inside the "2 screw assembly".
Make sure you pay attention as to which screw goes in which side of the frame.

I keep the 2-prong screw driver and a regular blade screw driver in my Range kit always. The regular blade screw driver is from Grace and is ground special to fit Ruger screws.

I shoot IHMSA silhouettes with mine, 40 high power loads per match. After every match I clean it and tighten the grip frame screws and check the base pin screw. Some are generally loose.

You can get a locking base pin from belt mountain. These are nice for pins that won’t stay put.
