Ruger MKIII jams

Thanks. I'll do some testing. It is a 22/45 and all was well until the Mini Mags.

Tested Federal HP's and had the same feeding problem. Then Mini Mags, round nose, solids. 100 rounds and not one single FTF or jamb of any kind. Nice to know about the HP's. Don't need them anyway for poking holes in paper and tin cans. I guess my 10/22 can eat those HP's up.

Thanks for the tip.

I had problems with my new 22/45. I just kept shooting it,round after round, mag after mag. 5-6 hundred rounds or so and its running really good now.Once in a while I get a jam, very rare...

I am a bit confused as to why 22/45s would tend to have more feed issues than the others. It looks to me that internally the magazine angle is the same in "normal" and 22/45 models. What am I missing?

All I feed to my MKII and MKIII 22/45s is Federal bulk 36g HP. I very rarely have any feed issues with either gun.

I wish I could tell you specifically why but I cannot. Could be the lighter bullet combined with the lighter frame. But most of the folks who've reported jamming issues over the years, especially ones where the bullet nose digs into the feed ramp, are hollow points and 22/45 frames.

That certainly is the case with mine. I've since fired some 250 rounds of Mini Mags RN without a jamb of any kind. With HP's I was getting 1 or 2 in each magazine full. Yet the bullet profiles look to be the same or very close to it.

Thanks for the responses.

I have had the MKII for just over a year and the MKIII for about 6 months. I have put a couple of thousand rds of Federal HP through each of them with no feed issues. I have had a couple of rds hit the feed ramp on the first rd in the mag but that has been explained in this thread nicely.

I love these guns! The wife snorts at me and my little toys, she likes the boom her Wart Hog makes. go figure

There used to be a time where people were falsely claiming it was the angle of the magazine that made the difference in feeding. But this is not true. The metal magazine bodies used between the metal frames and the plastic frames are identical. It is just the magazine bottom blocks that are different. You can take one magazine and swap the plastic bottom block and it will work in the other version frame without a glitch. It is true that the grip angle on the plastic frame models is less than the metal frames because they emulate the 1911 grip, but as your picture shows the installed magazine has exactly the same angle as it's metal framed counterpart because of it's positioning across the shallower angled grip. That is, the 22/45's magazine bottom block forces the mag body into the identical angle of the metal framed Ruger .22 Auto.
