What are you guys currently using, what have you used in the past, and what were the results using each?

To date, I've shot 10mm using stock Colt 10mm 8rd, Wilson 10mm 8rd, Wilson .45acp 8rd, Wilson .45acp 7rd, CMC 10mm 9rd, and CMC 8rd .45acp Power Mags, with pretty good success, load dependent.

Just went out and shot 300 rds. through a D.E., using the Wilson, both 10mm and .45, stock Colt 10mm, and CMC .45 Power Mags, firing 170gr. LSWC, loaded at 1.252", pushing 1100fps. WORST feeding was experienced with the Wilson 10mm mag!! (2 FTF's and sluggish first round feeds from from topped-off mags). Had absolutely zero problems with any of the other mags! Looked to me as though the Wilson 10mm mag provided considerable pitch angle constraint at front of loaded round, causing shoulder of SWC to dead-head into barrel ramp at too low of a pitch angle, while others, esp. .45 mags, provided little fore-end constraint, allowing easier rotation into chamber. In the past, I've used a lot of 170-180gr LTC handloads, and 180gr JHP loads, wherein the Wilson 10mm mags worked very well. Interesting.

Your thoughts? Talk to me, Goose...

Here are my experiences with my Delta Elite:

1. Stock Colt 8-round magazines. Stock springs seemed weak, with Wolff XP magazine springs they have worked fine. No magazine related malfunctions.

2. Chip McCormick "Shooting Star" 9-round magazines. Function has been 100%, but they present some other minor problems. They are extremely difficult to seat in the pistol when loaded to capacity. Also, re-assembling them is a pain in the neck and if you don't seat the follower on the spring right, it won't stick up at the right angle, which will prevent it from locking the slide back. I stuck some of the Wilson Combat glue-on base pads on them and they fit just right, also look alot better than the big CMC pads.

3. Metalform 9-round magazines. I got 2 of these and they caused frequent premature slide locks. Threw them in the trash.

4. Wilson Combat 47D 8-round .45 ACP magazines. Not a typo. I had some laying around, and several people claimed that they worked in 10mm. They don't.

Thanks, CB.
Interesting to hear about the Metalforms. Have never used them. BTW, my Wilson 47's and 47D's (7&8 rd .45 mags) DO work in my D.E.'s and in my Burns-modified Kimber 10mm. Hey DougC, you've had similar experience with the .45 mags in a 10mm gun, right?

I've got both McCormick and Metalform and it appears to me that the tubes are identical: it would not surprise me at all to find out that Metalform OEMs McCormick's tubes. However, the followers that come with the Metalform magazines are absolute crap. If you replace them with McCormick followers, they're fine.

I have been using CMC Shooting Star .45 mags, Wilson 8rd .45 mags, and Metalform 9 rd mags with the orange follower. All work in my Caspian single stack. The only problem I have with the Metalforms is that half the time they do not lock the slide back after the last round.

Yes, Dave. I use my .45 cmc shooting star mags in my Caspian ramped bbl. 10mm pingun with alarming reliability. Ran over 3k worth of 155jhps at 1350fps and 180s at 1250 this summer through both cmc 10mm mags and cmc .45 mags, with no problem. Scott Mulkerin, who built the gun, stated that some guns will run the .45 mags, some wont. Mine does, and I cant find anything wrong with the cmc 10mm mags. I am going to buy some more this winter. Enjoy the 10mm! be safe, DC

I've only had good luck with the factory mags. Colt sold them with and without base pads. I like the formed metal round top followers. They don't get pushed out of the way by the slide stop like the flat ones. I've tried the wilson 45 mags and the gun turned into a jam-a-matic. Maybe if I tweeked the lips it would work but I don't want to ruin a good 45 mag.

The most reliable mags that I have used are by far the Stock Colt Mags. I use the McCormick 9 Rd. and find them also very reliable. On thing I have found over the years with the 10MM mags is, if the lips start to open up, you start to have problems. I have a die made that I use to reform the lips and keep them as they should be.
I have found that many 45 Mags work as well as anything out there. I have some old original Devel 45 Mags that work great in my 10's.

I've heard that Wilson's 38S mag is supposed to work well for 10mm. Ordered a couple yesterday, to see for myself, and to compare to their 10mm mag. I'll report what I find.

The Wilson 10 mm magazine and Wilson 38 Super magazine difference ... a quick look ... and quick measurments ...
Lips 10mm .345" 38Super .330"
Grove 10mm .490" 38Super .450" (deeper)
Back 10mm .3435" 38Super .3275" (of the magazine cut)
Follower 10mm Covex 38Super Concave
Back 10mm Oval 38Super Round (cut out where the follower is exposed)

There is about 11 years difference in the magazines. The tubes are really quite similar. The 10mm round I tried is quite snug in the 38 Super magazine do to the depth of the material displaced to the inside of the tube vs the 10mm tube (about .040").

Has anyone tried Meg-Gar 10mm magazines?

Looking for your range report Dave.

Thanks for the data, Mike! Have you any experience shooting 10mm from the 38S mag? Apparently, one of the salesmen at Wilson is suggesting these for use with the 10mm. Keyword..."salesman". :wink: Just thought I'd find out for myself.

Funny, when I called Wilsons the "Salesman" told me to use the 45 mags. I did and lost the match with a lot of jams. Guess I should have tested them before the match.

Dave, I have not tried the Wilson .38 Super magazines in the Parker or the Delta. I got my Colt used with 4 Colt 10mm magazines.

The one 10mm cartridge that I tried in the Wilson .38 Super magazine was tight and you could see a little expansion at the front.

I just did a visual comparison of my Wilson 10mm to my Colt 10mm and the top of the tube and feed lips are virtualy identical. There is a couple of Met-Gar 10mm magazines in town but $23 each.

I have not been to the range (outdoor)with the Delta yet. I have been debating weather to get a Wolfe 20# first as it has a GI recoil setup with the two factory springs, not the full lenght guide rod.

It's too bad Rogers of the Wilson/Rodgers magazine doesn't make a 10mm since Wilson quite making them. :roll: Mike

Quick update: DO NOT bother trying the Wilson 38 Super mag for 10mm use...It won't work! Looking at my newly arrived sample 38S mag, the 10mm case (what, 0.425" diam.) is measureably larger than the opening gap in the mag between the groove indents. Didn't measure this gap (don't need to!), but the mag body in this area has to be visibly separated in order to insert a round. Tight friction fit, and looks to me as though this opening gap is maintained for the full height of the mag, so can't just "open up" the lips. Won't work. Damn! :sad: Will likely stick with the CMC mags, for now.

I use factory mags with red followers and Wolff +10% springs. They work great. Course my 10mm is an EAA Witness. :smile: Marcus

Good thing about the red-follower mags, too... the older black-follower mags make the gun a jam-o-matic.

Wilson Combat make the coolest magazines, but ol' Bill Wilson seems to have some perverse anti-10mm fetish going, and since Colt and CMC work just fine I guess there is no point horsing around trying to get his stuff to work.

I have three Colt mags and three Mec-Gars, and they all work (one FTF in 1300 reload rounds).

I've taken Metaform mags, junked the orange sticky followers and converted them with 38 super/10mm Wilson followers and springs.

In a word....awesome!

Hey MP-5, that solved my problems. My 9rd Metalforms, while feeding wonderfully, would rarely lock the slide back. I replaced all but one of my Metalform original springs and followers with Wilson Combat .38Super springs and followers. On one mag, I just replaced the spring, just curious to see how it works in a match.

Let us know how that works... and do they still hold 9 rounds?

Yes, they hold 9rds. Took awhile. At first they were a little stiff and I could get only 8 into them. After the springs got loosened up some, they would take 9. I have six mags, four of the mags work great, two others will not lock it back. I think these are just cursed. I have changed springs and followers with no luck. They feed great though. If I am required to do a Tac Load on a stage, I just use these first.

Do those Metalforms have removeable base pads? If not, I wonder if you could do the same thing to the CMC 10mm mags?

These have the welded on base. Do not see any reason why it would not work with CMC mag bodies.

Today I changed out the slide stop (have a couple of extras) and the Metalform orange follower w/ Wilson spring seems to be working the best right now. I changed out the Wilson follower with the Metal form follower on a few to see how it all works at next Sundays club match.

Several things going on here so everybody knows. I am trying to come up with an IDPA legal load, >125pf, in a 10mm case, that feeds perfectly, locks back, and is accurate. About have it figured out.

Okay, a CMC 10mm Mag question for Sean or anyone else:

The 9rd CMC mags come with a bulky, black base pad, pre-drilled with 2 screws. Does Brownell's (or anyone else) offer smaller base pads with a trimmer appearence that will fit these 10mm CMCs mags?

Sean, in one picture of your DE I saw with the mag inserted, it had a different black base pad than on the CMCs. Was this a Colt mag w/ factory base pad, or perhaps something else?

Thanks in advance for the help.

I got my CMC magazines without the big, ugly CMC base pads. The base pads on my mags are Wilson Combat glue-on base pads. You roughen the bottom of the mag & the bottom of the pad with sandpaper and glue them together with contact cement.

Hi,
I had used the CMC 10rd 45ACP magazines for my single stack 10MM gun back in the mid 90's. I had no problems with them at all.

Talk about an old thread.

I am down to two mags. Colt 8rd 10mm mags or CMC 9rd mags. The Metalform mags will feed just fine in both my Caspian based 10 and my Delta, but it locks back the Delta prematurly and may or may not lock back the Caspian.

As the Caspian is a pure game gun, it is tuned to run more reliably with the CMC 9rd mags. The Delta, is an occasional game gun and I carry it some in the winter or when I go hunting. So I just use the 8rd mags for it.

I have used the Cobra 9 shot mag and have had very good results.
I recentely tried the Wilson 47D(45acp) and found it to 100% reliable.
I know there are indiviuals on this board who say the Wilsons do not work others clain they do. It was experince they functioned 100%.

10 MM Mags

Ive got two Mec-Gars that I bought and one Colt that came with my Delta Elite. All three have worked wonderfully for a couple of thousand rounds.

Well, I have seven Colt blued 8 round mags for my Delta. All have the rounded followers.
The one that came with the pistol, five that I bought thru Brownell's and one that I picked up off the FS forum on Glock Talk which was brand new.
I have Wolff + power mag springs in four of the seven. Function was never an issue, I just did it because I read that some experienced better feeding with these springs than with OEM springs so...
I just ran 536 rounds thru my Delta the other day using all seven mags. They all functioned 100%.
I'll stick with the OEM Colt mags for now.
I also have two Tripp 10 round Cobra Mags which I bought by mistake. That's another story.
I've only put 20 rounds thru each but they run 100% also.
