Mimber 22 slide mags

[SemperFi1977m]

My Advantage likes CCI minimags and Rem golden bullets. All conversion kits are HIGHLY ammo-sensitive. Its hard to deviate from the recommended ammo without causing cycling problems. I didnt see it mentioned, but besides putting in a light hammer spring....these kits also like to run fairly wet. They need all the assistance they can get to reduce the effort to cycle the slide back with just a 22. Let us know if you get her ironed out :-)

Im looking to build a dedicated reciever for mine also as time and money allows.

At first I had the slide on my DW Panther frame, which IIRC has a 17 pound mainspring. The hammer strike was not heavy enough and I was getting *many* misfires and squibs. I believe part of the problem was that the firing pin was binding and not moving freely. It has loosened up considerably now.

Then I put it on my Colt frame, which at the time had a 23 pound mainspring, and I didn't have any more misfires, but massive feeding problems.

If I had it to do over again, I'd definitely get the GSG instead of trying to fool with the Mimber slide.

Here is a list of the things I have done to try to get the darned thing working:

1 - Polished and greased the firing pin to try to eliminate misfires

2 - Changed frames

3 - Changed mainspring (23 to 19 pound)

4 - Modified two of three magazines to remove excess material at the top

5 - Tried different ammo -
--Remington Thunderbolts, (burns so dirty they won't chamber after 50 rounds, half are subsonic and half supersonic, many duds)
--Remington Golden Bullets (many duds)
--Federal Champion Plated Hollow Points (1 jam out of every 20 rounds)
--CCI Blazers (1 jam out of 100 rounds, burns a bit too dirty)
--CCI Mini-Mags (seem to be the only thing that works but are too expensive)

6 - Tried running a boresnake through every 50 rounds

7 - Polished the rails

8 - Switched from Wilson grease to RemOil on the slide to reduce drag

9 - Modified the firing pin retainer

OK, I made it through two entire matches now with only one jam, so I think the Mimber Mag issue can be laid to rest.

You just have to file down the ridge on top of the feed lips, if there is one, and it works.

Here are the last two mags I bought:



Three of the five mags I have, including the one that came with the slide, looked like the first picture when new. Two looked like the second picture.

Now they all look like the second picture...

I'm happy to report that the Mimber slide (mounted on a Colt MK IV frame) made it through an entire Ruger Rimfire match this evening with ZERO malfunctions of any kind.

This is the first rimfire match I've ever made it through without a single misfire or jam.
