Mark III, 22/45 Safety Ball & Spring Detent reassembly

Post by ChuckInMass » Sun Jan 09, 2011 10:08 am

New member here, and apologies if this has already been answered, but I cannot seem to find it.
I bought my wife this gun for Christmas, she loves it, but I decided to add the Majestic arms hammer kit to bring back the Mark II functionality.
I used Bullseye's superb reference for disassembling and reasembling. Got the gun back together, bolt works, trigger works, no more magazine auto ejecting, and the pull seems nicer, boy was I smug and proud!
However, in one last check, I asked myself, is the safety lever really supposed to flop back and forth - then I saw the little tiny spring with a steel nipple, on the table. Went back to Bullsye's reference, and read the "Be careful with the safety ball&spring detent".
Disassembled it again, and cannot, for the life of me, figure out how or where to put the detent ball & spring back for the safety. Anyone have a pic or instructions on how to replace this? Desperate to fix this before wifey finds out I trashed her new gun (and she is really good with my AR-15, .223 :oops: )
Chuck :(

On Bullseye service for the 22/45 if you scroll all the way down to Bolt Latch Slingshot Modification it shows the detent. http://www.guntalk-online.com/2245detai ... .htm#ssmod
I use a dab of grease on the spring and plunger to hold them in place so they do not fall out. You have to put it in and rotate it down into place.

Hi Blue68f100,
Thank you for the reply. I apologize if I did not explain my problem clearly.
My problem is replacing the ball&spring detent for the THUMB SAFETY LEVER.
(Wife just came home from Wally world with 2-500 rnd bulk boxes of .223 - help!)

Hi Chuck, welcome to GunTalk-Online!

What Blue is trying to say is the detent ball is the same between the 22/45 latch and the thumb safety. It goes into the thumb safety lever in the same manner. You have to strip down the gun and remove the safety lever and place the spring and detent ball into the rear bottom side of the button on the thumb safety. Here's where a little dab of grease will be helpful to keep it in place until the lever is installed back into your pistol's frame. Here's a picture of where it goes:

Hope this helps.

Ahhhhh, (Slapping forehead, soundly)! I never noticed the little hole in the button, been staring at this for 3 days, and totally escaped me!

Thank you bullseye, and blue - I really appreciate your taking your time to help me out.

Will have this together in an hour now, before wifey finds out. Funny thing, I thought I conqured the hardest part, getting the sear spring on.

I hope I can contribute here, eventually, pistols relatively new to me, being a rifleman in vietnam and elsewhere, never really had a chance to play with pistols.

Happy New Year to all
Chuck

You did conquer the toughest part but unfortunately that little ball dropped out. It doesn't always happen but when it does typically the problem goes unnoticed until the pistol's all back together. Sometimes that little ball and spring is hard to find. It often drops into the bottom of the frame and has to be shaken out to locate.

Have fun,

Yet another question

Post by ChuckInMass » Sat Jan 22, 2011 8:16 am

Again, thanks for all the help, guys- overlooked the obvious.

I do have another question on my Mark III 22/45, the Trigger Pivot Pin seems awfully loose, and looking at the schematics, I do not see a retainer spring like the one on the Sear pin.I have fired less than 50 rounds on this pistol, as the weather has really not let us go to the range, so it cannot be wear on the pin.

I actually have to push the pin back in every time I pick up the pistol and I am concerened that it might drop out while I am firing it.

Has anyone else experienced this?

Thanks,
Chuck

If the pin is reversed the sear spring will not lock it in place.

On the safety detent use a dab of grease to hold the spring and plunger in.

Is your pivot pin retainer installed? It's a curved piece of spring wire with a hook at one end that fits in the notch of the pivot pin. The straight end clips under the right side of the big hook for the receiver. It's shown in the "exploded view" in the manual, part number 30.

Maybe I am calling the pin incorrectly, this is the pin I am referring to. You way there is a spring/retainer for this Pin?
Thanks

Yes, that's the trigger pivot pin. The retainer spring fits in front of it, to the right, inside the frame. It's a curved wire, with a few "kinks" a little over an inch long. I think the detail strip post

shows it. Click on the pictures to enlarge them.

Brownell's has a Mark II 22/45 schematic that shows the retaining spring positon better than the Ruger manual does. Not owning a 22/45, I didn't realize it also helps retain the mag release. On the regular Mark III, a screw does that.

http://www.brownells.com/.aspx/pid=0/si ... k_II_22_45

The retainer is part 63 in the box. Shows its installation with the trigger pivot pin and the mag release button.

The trigger pivot pin is grooved on one side to lock into the frame. If it is installed improperly it will not stay locked in place. Here's a pic http://www.guntalk-online.com/images/22 ... smod07.jpg of the pin. The grooved side goes on the right side of the frame. There is a piano spring on the right side of the frame to hold the pivot pin in place. It is also the same spring that holds the magazine release. http://www.guntalk-online.com/images/22 ... smod02.jpg
