Ruger MK-IV, minor problem

Mods, not sure where to park this and perhaps Y'all are aware of this. I received this mailing from Voltquartsen and thought I'd pass it on. ...

Unfortunately on the Ruger® MK IV™, heavy use can cause the Bolt Stop Cross Pin to work its way out and cause malfunctions. Our V-Lock Retainer is a simple fix to prevent this issue on both the target frame and 22/45™ frame.

Be Safe !!!

I hate that pin. Guess I have a part to buy. Always walks to the right on me. Was halfway thinking someone should make a drilled and tapped pin with a flat screw slightly larger than the hole to hold it in place. Didn't realize it was just a simple pin.

And it's ordered.

Thanks for the information. Any problem with the pin on the Hunter frame?

The article was listed the MK-IV, so yes, I suspect it holds true for the Hunter...

I did not post the picture but the "fix" part is just a metal clip. I'm a Ruger fan and really don't have a desire to own an MK-IV

Contact Volts and see what they say. ....

Be Safe !!!

The Mrs has a Mk IV that I installed the Voquartzen competition kit in & that pin was walking out on hers too. Mostly we caught it but it came completely out once & I carefully made the retaining grooves on each end a bit deeper & it seemed to really lock in when replaced, plus I put a dab of red loctite on each end of the pin in place & zero issues since.

The video they have of the fix is way to easy. Then I realized the demo frame is gutless. Is there actually and easy way to do this or is it an everything out. I ordered an Apex trigger kit just in case. If I'm going to take everything out i'm going to put other things in.

My Apex trigger kit showed up today so I dug into the gun and I figured out my retaining pin problem. There was no pin retainer. I bought this new at Cabela's so nobody has been in it besides Ruger. And now myself.
