22/45 Tune-Up?

chasn · Post by **chasn** » Sun Feb 07, 2010 6:31 pm

Hi everyone, long time lurker first time poster.

My 22/45 is right at 10,000 rounds, give or take, and I was wondering if it's the right time for changing the springs out? Also, which springs would require replacing... hammer, recoil, firing pin, etc.? Is there anything else that needs looking at?

And finally, what is it's lifespan? If it's 30,000 (the most I've seen on the boards) then it's almost a third of the way through! I'm hoping it's more like 100k.

Thanks in advance...

I dought that you will ever shoot out the barrel, my guess >200k. As far as springs, I have not heard of any maintance schedule for them. If you only shoot std or high velocity ammo like ruger recommends I do not think you will wear any springs out. Bullseye may have a answer but have seen any schedule posted.

Welcome to the forum. I agree with blue68f100. I've never heard of a spring replacement schedule other than when one breaks. My guess is >200k. Sounds like long-term testing is required.

The only spring I've ever wore out in a MKII is the recoil spring that rides on top of the bolt, Usualy the wings will shear off with wear but had one recently that just needed replacement as the spring was weak..
Also these springs were aquired from Ruger with just a phone call & the serial number, There customer service department is top notch..
Then there is the fireing pin return spring that you could possibly get them to send you one of as well..
Good Luck!!

You're in no danger of wearing out your Ruger 22/45. Unless you abuse it with hyper velocity ammunition it will last you several hundred thousand rounds. Springs can wear or break and inspecting them regularly during field stripping and cleaning is recommended. Don't forget that little spring inside the bolt for the firing pin return; it can break with extended use. The springs are pretty durable and as such don't need replacing like some higher caliber models. I've not replaced any springs for life cycle issues just ones that were broken.

It is a good idea to inspect the other components for signs of wear when performing routine cleaning maintenance too. I know that there have been some issues with 22/45 Mark III receiver tubes cracking up the LCI pin hole to the LCI lever hole after heavy use. Extractors, firing pins, firing pin stop pin, recoil guide rod assy, and mainspring assy are all good things to periodically inspect for wear.

Thanks for all the info. I'm gonna do as y'all said and just check it out every cleaning, which I do after every range trip.

Also happy to know it has 'lots-o-life' left in it. Celebrated by running 600 thru it today

I would not detail clean the gun every range trip. If your doing so you may loosen the fit between the barrel and frame. I only detail clean every 1500 to 2000 rounds. I do remove the bolt and clean in between detail cleanings when it's get dirty. A quick run of a nylon brush is what I use to clean the barrel. A bore snake will do for those in between times.

Funny you should mention that... when I first got it I had to use the customary whack to get it apart. Now it only takes a little thumb pressure and off she comes.

I'm not feeling any slop between the two though. And I did make a blast shield so that's probably helping. Thanks for the tip...

I was going to mention that you probably don't need to clean after every trip, but blue68f100 got there first. However, should the fit between the grip frame and receiver get too loose, there is an easy fix for that.
