You'll be AMAZED at how much nicer your housing will open and close!
That's a great tip. Never realized this. I've two of my MKIIs with tight latches I'd like to try that on.

I polished mine as well and I use a pulled open paperclip (small loop section) epoxied into a 9mm spent cartridge (Large loop epoxied into the cartridge). Been using that setup since the 60's.

These have been discontinued by Brownells but still available directly from the maker.

Followed your lead, works great.

Use this with caution because it can make some nasty scratches if you're not careful, the same as any other screwdriver you might use.

[The fishing leader does work great. I started using one in the 1980's but I eventually lost it. Now I just use a lady's bobby pin. A whole box of them are dirt cheap. Just slip the eye of the bobby pin over the end of the lever and pull. No. scratches on your mainspring housing.]

I would definitely go with the string and ring as opposed to any kind of metal prying.

Yep, the GST does work very well in releasing Standard-MkIII MS latches "without a scratch". I really like the internal pin used to release spring tension on the extractor...very robust and works Great. One has permanent residence in my range bag!

The Gunsmither Pistol Pal was designed to provide 3 tools in 1. A loop for pulling out the takedown latch, a punch for driving out the bolt stop pin, and a pin for depressing the extractor plunger.

I sure could have used one when I bought my first MKIII. That, and a 5lb sledge hammer.

Anyway, after radiusing the latch as in post 4, I open it easily now with my thumbnail. After deburring the stop pin holes in the receiver, the pin goes in and out easily by hand. And I added a notch to my extractor plunger to allow any small screwdriver to hold it back for replacing extractors.



I've found that I still need a second tool to wiggle the extractor free when using the push pin method. But it falls out on it's own when using the screwdriver slot.

Deburring the front and back of the frame made it easy to separate/join the receiver and frame without beating on the upper. I still use a small plastic hammer, but it only takes a couple light taps to get it done.

I always have a thumbnail and my Leatherman screwdriver with me. So carrying around extra tools is something I just prefer not to do.

Call and explain to Ruger-they may send you a replacement.

I usually have to tap the business end of the barrel to align the bolt stop pin on my pistols. I also discovered if I tap the barrel to the rear before I attempt to remove the bolt stop pin, it comes out much easier. When the bolt and/or firing pin slams forward during cycling it moves the barrel assembly forward a tiny bit, just enough to make the pin difficult to remove.

Have a blessed day,

Leon
