Yes. By far most of the time it goes in corectly. That time it didn't. The problem is that the mainspring housing binds into the slot so badly, that I don't know if it is in right until I test the slide. I don't get the spring back like all videos show including Ruger's own video because the MS binds so bad. It's even difficult to pull out when everyone else's pops out because of the tension on the spring.

I wonder if they would just send me a new MS. I can't say I would like to send the whole gun in just to replace a piece that is removed by the end user for disassembly and cleaning - although I technically can't rule out if the slot in the grip is crooked and a straight MS thus binds.

That strut has come off of the mainspring housing and is caught behind the frame crosspin. Open the housing swing it out and re-seat the strut on the mainspring cap and close the housing again.

I got it back ok. The problem is that the mainspring housing binds into the slot in the frame so badly that I don't know if it is in right until I test the slide. I don't get the "spring back" in the last 1/8 inch like Ruger's own video because the MS binds so bad. They even refer to this tension as "the secret to you firearm" on the video. Mine doesn't have this because of the binding.

When you look at the housing, inside the grip frame, is the gap along either side of the housing even?

It's not even close, you can see that the housing sits crooked with some twist to it inside the frame. That's what I meant by it binding in the slot. It pushes hard into the slot. That's why I don't get that "spring-back". It is difficult to pull out of the frame too - not difficult out of upper receiver.

If your mainspring housing is distorted/bent, it can cause problems with the hammer dropping. The hammer spring (mainspring) needs a straight channel to apply pressure onto the hammer via the strut. Any binding and the hammer may not have enough force to detonate the cartridges properly. Not to mention the difficulty you're having removing the MS housing when you field strip the pistol. This would be a good item to call Ruger's customer service about. They can send you a replacement MS Housing without you having to send in the whole pistol for repair. They'd just want you to send back the retrograde housing after you replace it with the new one.

Looks like it's a call to Ruger. What a disappointment on a brand new firearm though. It's my first issue on a handgun in just over 30 years. I know things can be wrong, but you'd think the person putting it together at the factory would have caught this rather than just keep up their quota on number of assemblies per hour. I will hope Ruger's CS is better than their assembly Dept.

Thank you very much for your info and help with this.

Bullseye

When you call them, it would be even better if you can email them a picture of the mainspring housing in the frame. This way they can see the distortion and that will just make it easier for them to send you a new one.

Thanks, that's a great idea. I will email them a pic today and call tomorrow from work.

The MS housing really does sit pretty crooked. Enough that even the left side sticks out of the frame while the right side sits flush to the frame. It's bad enough that it probably should have been caught at the factory so it wouldn't have become the customer's problem.

Bullseye

You are probably right but that is easier to say when you don't have a hundred of these pistols sitting in front of you on a rack. They understand that internal parts sometimes are defective and do everything they can to make it right.

I'm sure Ruger will get you fixed up. It's to bad it happens but as Bullseye said when you're turning out items in large numbers things do get by. The more time they spend on each gun the more the price goes up. As long as they fix them. I know it''s a pain but these are mass produced. And the demand for guns keeps going up and up. This is a well proven design and they're great guns that will probably out last us.

Bullseye

Another plus is the mainspring housings are mass produced sub assembly parts and they do not need to be fitted to the individual pistol for it to operate properly.

That's good. Maybe it will be less hassle to get one mailed to me. I looked very carefully and I believe it is the MS that is warped and not the slot in the frame. I looked on Ruger's website and they have a way to submit for CS support but no way to send a pic. I guess I will just call and hope that goes well.

After I get through this, I will use your advise above to evaluate the trigger where it hangs up a bit before it moves and clicks. Funny thing is I didn't notice this at the LGS but then noticed it at home before I shot it. I am used to a smooth but crisp High Standard trigger so this one was a surprise given how popular the Ruger Marks are. Do the older Mark IIs have this same trigger?

Bullseye

All the Ruger .22 Auto triggers operate in the same manner regardless of generation. Some are a little smoother but they work the same. These pistols don't have the same trigger feel as a High Standard or Smith 41.

When you talk with CS get the email address for a technician and send him the picture as an attachment to your message. You want to contact the Prescott AZ customer service department as they service the Mark's.

As suggested, go shoot the day lights out of it. 500 rounds make a big difference, 1500 rounds makes a totally different gun out of it. It will also help your shooting skills (not saying you have any problem).

Getting rid of the mag safety (otherwise known as the lawyer safety) makes the gun more fun to shoot.
