I have a lightly customized Colt Delta Elite that is giving me magazine-related fits.

When I bought it (bone-stock) it was used, and the magazine it came with was used *up*. No problem, I got a couple of CMC Shooting Star 9 rounders. I have since put several hundred rounds through it and discovered something.

With 8 rounds in the magazine, it is functionally perfect. No foul-ups of any kind with any ammo. Me and my friends probably put 200 rounds of Blazers, various hollowpoints and cast handloads through it without a hitch.

With 9 rounds in, however, it has an alarming tendency to miss-feed the top round in the magazine. The spring seems so strong that with 9 rounds in it actually binds the top round against the feed lips to the point that it causes malfunctions. All the subsequent rounds feed fine, leading me to belive that the magazines are the culprit.

This annoys the heck out of me. So I bought a pair of Metalform 9-round magazines. These are even worse: not only does the top round cause fits when it is loaded to 9 rounds, the magazines also lock back the slide on the next-to-last round EVERY SINGLE TIME!

Oh, and anyone that tells you that Wilson-Rogers .45 ACP magazines work in a 10mm is dead wrong... I had some (for an actual .45) that I tried out based on the advice of a closet bonehead. They caused so many malfunctions that I won't even bother to list them.

So what magazines SHOULD I be using? I don't care so much if they are 8 or 9 rounders, as long as they actually work when loaded to whatever their designed capacity is. I ordered some new Colt 8-round DE magazines to see how they work. There are also Colt 9-round DE magazines; will they actually WORK when loaded to 9 rounds (unlike all the others I've tried...)?

Thanks in advance for any helpful replies.

Ok, I'll play. I had the same exact problem with my 9x23. I never tried the Metalforms in my Delta, but I'll try to impart what I've found. Sometimes you can take the Mags and load them to capacity and leave them loaded for a month. This should set the spring and reduce the spring pressure push against the bottom of the slide causing the slide not to cycle. A guy told me this weekend at an IDPA shoot that you can cut a coil or two off the mag spring. I use the 8 rounders with pads from Colt with the rounded steel follower, no problems.
With the slide locking back before the last round, put one round in the mag and check to see if the follower is pushing up on the slide lock. Any pressure and the slide lock will jump up and lock the slide. If its jumping up becase your shooting hot loads you may have to dimple the stonp where the plunger lays against it. If the follower hits prematurely you have to lower the pad on the follower. Hope this helps its frustrating when no one answers a post.

Hey, CB:
I've got a few Wilson 10mm mags for mine, which function fine. I believe they have stopped making them, however.

Add'l S-2 quote: "HUH...They did WHAT!?!...OH SH!T...Well...I knew they'd do that! :smile: See ya.

Yeah, WC doesn't make 10mm magazines anymore. I would have gotten them in the first place if they did. :mad:

Oh Bill Wilson, why hast thou forsaken me?!? :cry:

Is that weird or what?

Is there a big issue with makin' that particular mag, or just not cost effective?

What is the maximum OAL for the 10mm loads you use the most?
I'll look up the other stats on it...Tht's gotta' be a bummer! I was lookin' at a EAA in 10mm, at least they have mags for 'em. Still...I'd ALWAYS rather have a 1911...:wink:

I'm just using factory ammo mostly: Speer Blazer 200gr, Winchester Silvertips, Pro Load 155gr JHP and a couple of boxes of 155gr cast handloads a friend provided. No matter what the ammo, though, the behavior of the CMCs is the same:

9 rounds, top round sometimes misfeeds
8 rounds, runs like clockwork literally 100% of the time

All hiccups have happend with all ammo types when loaded to 9 rounds, and all ammo types worked great when loaded to 8. Getting the last round in is pretty tough, the spring seems really heavy.

Wierd, huh?

Hey folks,
Let's all e-mail Bill Wilson, and suggest
he offer the 10mm mags again. I personally
just take the .38 Super mags and have the
feed lips opened a little. Both mags use
the same follower and spring, so that's no
biggie. Don Williams at the Action Works
can do this, and he has some Wilson 10mm
mags to compare them to. Wish he'd sell
'em to me......
