 Another cure for the Ruger MKIII magazine safety.

I have always disliked magazine safeties on all firearms as I think they give people new to firearms a false sense of security and they are just simply unnecessary parts. I especially do not like the mag safety on the Ruger MKIII as they do two things to the function of the firearm. They give the trigger a gritty pull and the mags don't fall free from the mag well, requiring you to strip them by hand.

I have seen different fixes like grinding a washer to fit, but I wasn't fond of the idea. I was contacted by a member here, SG552-2, with an easy solution for my problem. He told me he makes his own bushing to replace the factory bushing and then would allow me to remove the mag safey parts.

Here is the disassembly guide that I used for my Ruger MKIII 22/45 HERE


Here is the gun...




This is how far my mag would come out with the mag safety parts.




These are the different bushings:
Left- factory Ruger MKIII
Middle- Ruger MKII made by Volquartsen
Right- Modified Ruger MKIII made by SG552-2




Once you follow the disassembly guide link above these are the parts you will discard after replacing the factory bushing with the modified one.




Simply insert your modified bushing into the factory MKIII hammer like so and reassemble






The end result is fantastic! No more gritty trigger and mags rocket out of the grip frame now. I'm extremely happy and would highly recommend this to anyone interested in this simple fix. The fit and finish is top notch and definately worth the $10 bucks.

If anyone else is interested, you can contact SG552-2 at: sg552-2@hotmail.com

ETA: Sam has a new email, sg552.2@gmail.com

Great info and great write-up. I too am not a fan of the mag safety, but I assumed it would be more trouble than it was worth to remove it. Having a drop-in part available makes it a lot more viable for me. Thanks

Another solution to the problem is to replace the hammer and bushing with a VQ MK II hammer and bushing.

True, but the hammer is 46.00 and the bushing is 8.00. Shipping through VQ is 8.00. So that 62.00 to fix a $10 dollar problem. This is much more economical for some one just looking to loose the mag safety.

Got the part from Sam, but I have not tried it yet. Cannot wait.

I made a "filler" piece to fit the cutout in the hammer along with a MKII bushing, when I had mine. The item in the OP sure would have made things easier.

I bet whoever made 'em sells a ton of 'em.

I had a related question. I have a MKIII that I am planning on getting the VQ accurizing kit for it but also dislike the magazine safety, since I'm already ordering from them is their bushing worth it? or is the spring magazine release worth it? or should I just try and order this fix if he is selling them? It seems like VQ's bushing only solves the problem if you order the MKII hammer which is more money and negates part of what you get with the accurizing kit. Thanks for help.

I got my bushing a few days ago, looks nice. I haven't had a chance to put it in yet though.

Here are your options:

Order the MKII accurizing kit and the MKII bushing from VQ. You would then discard the parts shown above including the MKIII hammer. Or you can just order the modified MKIII bushing that this post is about and use your MKIII hammer. Both options will do away with the mag safety.

I ordered 2 bushings from Sam, they arrived today in the mail. Quick shipping and the bushings are very nicely machined, they fit exactly and I had both of them installed in my 2 MKIII45-TA Hunters in under 30 minutes. I stepped out my back door and ran 30 rounds through each of the MKIII's, the difference and improvement in the trigger is quite obvious and now the trigger pulls are very similar to my MKI and MKII's. Additionally, the magazines now eject cleanly from the grip frame with the removal of the magazine safety parts. Removal of the LCI's and Sam's bushings are exactly what every MKIII needs to 'improve' it back to the quality and reliability of the MKII...

Are they made from SS ?

It does look to be SS. I originally thought it was aluminum, but I just checked mine with a magnet and it stuck.

Then it's not stainless. Stainless steel is non-magnetic except in some very specific, expensive alloys.

Not true. If you have a stainless pistol, take a magnet off your fridge and it will stick. Stainless used in firearms and accessories contains a certain amount of iron. Magnets will stick.

And yes, the part is made of stainless.

I have Sam's Bushing in my new project:

Pics of Volquartsen modded 22/45

They Installed 4" match barrel larger OD to match receiver OD. Installed their sights. threaded the barrel, made a thread protector and bead blasted the whole upper to be non-reflective.

I did the 1911 Grip mod

I have a ruger mark 3 22/45 and just bought the volkswagon trigger and hammer assembly with the mark 2 bushing. The instructions show that i should reinstall the magazine disconnect and the two springs but can I put it back together with just the hammer bushing and sear and sear spring?
hkusp9  [Member]

I can't believe that nobody knows if I can just put the custom Volqartsen mark 2 trigger hammer and sear assembly without the springs and magazine disconnect in the ruger mark 3 22/45

You are correct, you do not need the mag disconnect if you replace the hammer and bushing with MKII parts

ETA: Sear is the same in both MKII and MKIII

400 series is generally magnetic and hardenable by thermal treatment
300 series is generally nonmagnetic and usually work or precipitation hardened

Just got finished putting mine in, and did the 'slingshot' mod while I had it all apart too.

If I hadn't forgotten to flip the sear forward before reinstalling the safety lever, it would have taken <10 minutes.

Another bump for a nice, niche product.

Does anyone have the dimensions on the Mark II and Mark III hammer bushing? How much difference is there?

Also wondering, if I want to tune the trigger and really practice for competition would it be better to buy the whole accurization kit? Volquartsen advertises a 2.25 trigger pull, but I want a 5 lbs pull so that the 4.5lbs on the 1911 seems like butter. Any suggestions?

I ordered a bushing last week and was very impressed with the customer service I got from Sam. All questions and emails were answered within minutes. I haven't received my bushing yet but if its as good as his c.s. I know I will be happy.

You and me both, this Sam Lam fellow is a very good guy, he responded in 5 minutes to my email, he answered ALL of my questions and I am in the process of purchasing a bushing from him.

I just removed the mag safety piece and spring, and had no problems. Never needed any other parts, just removed those two.

Have you fired it since removing the mag safety parts? Does it dry fire? Is it even possible to just pull these parts and the gun function correctly? If so, why are we buying bushings if all you have to do is remove the parts and reassemble the gun???

I did not notice any loose or misaligned parts.

I've been firing it in this manner for about 5 years now. No problems.

I was getting ready to order a clark bushing because they are all the rage on rimfirecentral for this issue and they say it improves trigger pull also so anyone ut here that can compare to the clark mark II that you pressfit into the hammer of the mark III. supposed to do wonders on trigger feel and function? this seem like a nice cheaper alternitive! am am curious?
