Need help with Ruger MK1

[Davidoff]

I just picked up this classic Ruger MK1 (A100 Frame).





I took it the range today, and I was having a malfunction at least twice a magazine. I had several types of jams, from FTEs and stovepipes to failure to go into battery. Now, I didn't give it a thorough cleaning before I took it out, just a wipedown, but I tried 4 types of ammo. The problems persisted with all loads.

I brought it home and took it apart, and it looks like the ejector might be broken. Ruger's website had a exploded view of the pistol, but the ejector was not pictured. Is there someone who has a MK1 from around 1980 who can tell me if it's broken or not? Here's a couple of pics:





Now the FTB issues may have just been because it was dirty, but the feed ramp is a little rough and may have contributed to the problems as well. Here's a picture of the feed ramp:



Any advice would be appreciated. I cleaned it up pretty good after I got home, I and might take it out tomorrow and try again to see if the problems persist. I also have a couple of MK1 magazines coming, maybe the mag is at fault. I tried a MK2 mag in it, but the problems were still there, and it was hanging up on the mag release like I read will happen with MK2 mags in a MK1.

Thanks.

Clean and lube, then see if you get the same errors. I would replace the mag spring next, and then the other springs in the gun.

+1.
Things rarely break on Rugers. That ejector is overbuilt like a tank.
My bet is on the mag spring. Its happened to mine before in my mark I

Typically these guns will run even when REALLY dirty and are not typically picky about ammo. That being said, I take home every new gun I buy and clean / inspect before I shoot it. Never know what the last "professional" who owned it did to it...

Looks broke to me. Send it back to Ruger.

Should stick out at least .285" passed bolt face when locked back.

I just looked at my MK1 and you have a broken extractor.

Thanks BSlacker. That's exactly the pic I was looking for. I guess it needs to go back to Ruger, I really don't want to deal with the rivet that holds the ejector in place.

I wonder if they would put a bull barrel on it while it's in the shop?
