Metalform Magazines Junk?

[Dieselman]

I purchased a Kimber TLE II 10mm a little while ago and wanted a few extra mags to go along with the single magazine that Kimber ships. To avoid confusion with my .45 1911's that run exclusively Wilson Combat mags, I chose to purchase a different brand for the 10mm that look visually different. (Don't want to accidentally grab a mag full of 10mm and stick it in my .45 if something goes bump in the night.) With this in mind, I set out to see what people like for 10mm magazines.

It appeared from my research that people were well satisfied with the round follower Metalform 10mm 8 round welded base. This one here - http://www.brownells.com/magazines/handgun-magazines/magazines/1911-10mm-magazine-prod71633.aspx?aid=27795&source=ir&cm_mmc=affiliate-_-Itwine-_-IR-_-59979&aid=27795&source=ir&cm_mmc=affiliate-_-Itwine-_-IR-_-59979 So I ordered two from Brownells and took them out to the range.

Upon loading the magazines with factory Remington UMC 10mm, I realized before ever seating them in my pistol that I had a problem. After loading around 4 or 5 rounds into the mag, the follower begins binding in the magazine body. When the mag is fully loaded to 8 rounds, the mag follower is so bound up that the rounds just fall out if tipped upside down. It requires a fair amount of tapping to get the follower freed up to return to the top. Both the Metalforms I bought do this and obviously don't function at all in the gun unless only loaded to about 2 or 3 rounds capacity. Anyone else have these problems with Metalform mags? I'm thinking about throwing them in the garbage and buying some other brand. Any suggestions on what to replace them with?

My gun functions flawless with the factory Kimber mag. It also performs flawless with 10mm rounds loaded into Wilson Combat .45 ACP magazines. However I am against using the Wilson .45 mags with it do to the possibility of accidently grabbing one loaded with 10mm and inserting it into my .45

Sell the .45 and use Wilson mags.

I've had three and all of them have done that and I've thrown mine away. I had problems with my WC mags so I gave them to someone on here, Tripp and kimber mags have been perfect.

Ultimately I got rid of my .45's they never left the safe, I wouldn't buy ammo for them whenever I had the money I'd go 10mm now .45 next time and it went on like that for over a year.

Until fairly recently, I believe that 10mm "Kimber" mags were made by Metalform.  Then recently, the 10mm "Kimber" mags were suddenly made (I believe) by Checkmate.

I never had the trouble the OP reports with my original Kimber (Metalform) mags.  But I WAS continuing to get some jams when firing, and so I switched to Checkmate mags (after trying almost all the other alternatives first, to no good effect).  The Checkmates gave me better reliability, and I still use them for carry.  But lately, I've also noticed that when I chamber the first round from a mag with only a single round inserted, that the cases and bullets get beat-up a good bit during the chambering, and the bullets often have some "set-back".  The original Kimber (Metalform) mags don't seem to do this as badly.  I'm going to use the original Kimber mags for some of my range practice, and if they now prove to be as reliable when firing as the Checkmates, I'll switch.  Otherwise, I'll just only use an original Kimber mag to chamber my first round ... with a slow slide motion, an Underwood Nosler round has recently been sliding right into the chamber like butter.

No can do. The old .45 is my primary carry gun.  The 10mm gets carried only when in the woods.

Metalforms work fine in all 3 of my 1911 10mm pistols.

[Pinsnscrews]

I have 3 of the Metalform/Armscor/RIA magazines for my RIA. They all work flawlessly.

BTW, since the magazines are meant to be disassembled for cleaning, why not determine what part of the follower is jamming and file it down?

Now on a lot of my Metalforms 10mm mags I put in the Chip McCormick innards kits to make them 9 round mags. I do like those.

Metalform makes very good magazines. I prefer them over almost all other 1911 magazines.

Metalform makes magazines for Colt. If you look at the bottom of a factory Colt magazine and see an "M" next to the Colt horse, you have a magazine made by Metalform.

Thats what the "M" stands for.

I just might have to give that a try

I have had zero problems with them, so it just may fix your problem.

I recently purchased a Rock Island 10mm Tac FS. It came with one metalform round mag. I purchased 3 Wilson Combat mags based on forum recommendations but  they occasionally don't lock back. Returned them promptly. I have on order some metalform mags. While I wait for delivery I tried using my chip McCormick 45 mags. They feed 10mm  ammo no problem but the slide won't lock back on the last shot. Anyone else have other recommendations ?

Tripp cobra mags and kimber mags work in mine. Tripp will lock your slide back for sure.
