Nope. Just passin' the information along. I intend to order about 60 or so, and if anyone local wants to run by and buy a few from me, I'll sell off about half the total...at the discounted price of course...plus the shipping cost per mag tacked on. That'd probably add maybe...10-12 cents per magazine.

1911Tuner,
Unfortunately, New York is not local to North Carolina, so I can't take advantage of your generous offer.
Out of curiosity, what is the price per mag if you order 50+ of the USGI style magazines? Also, what product number do you need to reference when you order them?
Thanks.
Sincerely,
Prof. A. Wickwire

Check-Mate Prices
Professor, the factory rep has indicated that the prices per magazine with a 50+ order will be in the $8.50 range for carbon and $10.50 for stainless, with the same pricing for true USGI-spec magazines...likely available in carbon only.
Don't have a part number yet, but contacting the company and asking for the Colt spec 7-round, tapered-lip magazines will get the right ones. E-mail:

I have no financial interest in referring anyone to Check-Mate, nor do I have a special deal in the offing for doing so. Just passin' the word along for good quality, functional magazines made to Colt's specifications.

Well,come on, lad! My latest addition is rompin' and stompin' since I had her spayed and got rid of the worms. She's gained about 10 pounds, and can't get enough to eat. Body was so depleted that she's tryin' to catch up, I guess. Tryin' not to let her gain too much too fast, but she begs so purty that I give in.
For all who don't know..."she" is a Siberian Husky with a Coyote in the woodpile about 3 generations back...or so the vet says. Another starvin' stray who decided that I was supposed to adopt her about 6 weeks ago. 100% baby doll and a purebred "Thief of Hearts" who'll steal yours in about 5 minutes flat.
That makes 14 dogs on-site.
Woof...

hey Tuner, would you care to categorize some of the popular mags so i'll know what you're talking about? (I only have one 1911 and one brand of mags and I shoot my 1911 a fair amount, but i don't know anything about how it works)
as far as the taper and late/early release are concerned, which of the following magazines fit which category? chip mccormick, wilson combat, the mags that come with the springfield "mil-spec" or "GI", etc
thx for the education

Magazines
Hi taliv. Hard to know the players without a program.
In the center, you have the early/abrupt release magazine with parallel feed lips. On the sides are the "hybrids" that have tapered lips, but a definite release point. You'll notice that it's a bit later and less abrupt than the center magazine.
USGI "hardball" magazines don't provide a timed release point, and the taper
extends much further. They release gradually, with a little drag on the rim as the round comes up. Some require a little adjustment to provide the optimum release point in some pistols, but they lend themselves well to that adjustment. I like to see the final release just forward of the dimple, with a very light drag on the rim, and use a gauge with a .473 inch rim to set that up.
The hybrid...the design that incorporates the tapered lips of the USGI and the
timed release point offers the best of both designs. This isn't to say that the
early/abrup design is not good. They work well in too many pistols to make that statement...including most of mine...but they do sometimes give problems that are neatly solved with the late/gradual release designs.
Here are the differences. I also have a picture of a hybrid beside a USGI mag that's had the lips adjusted for a slightly earlier release that show in the next post.

Here's a side-by-side comparison of the hybrid and the "hardball" magazine.
You'll notice the similarity in the tapered area, and that the release point of the GI magazine is slightly forward of the hybrid's, making it a bit later and even less abrupt...but earlier and more abrupt that a full hardball magazine.

fascinating!
my mags are all identical to the one in the middle of your first picture. straight lips, abrupt release. i shoot exclusively 200g hornady XTP and 200g lead SWC. and i seat them to 1.210" and 1.242" respectively. Those lengths were chosen for no real good reason other than it puts the shoulder on the bullet just a smidge higher than flush with the mouth of the case.
i've never had any feeding problems, but i do consistently get stovepipe ejection issues with the lead when i over-grease the slide and shoot more than 200 rounds (that's about where it gets dirty enough). (I can shoot >600 rnds of jacketed with no malfs)
part of the reason for the above is that as you've probably already guessed my launch platform is one of those compact models with the truck shocks for springs. when i shoot the light 200g swc loads (mean velocity 724 fps) i have to replace my normal spring with one i've shortened by two links.
so... do you think it would be possible to use a weaker spring if I acquire a tapered mag (or taper my feed lips with a pair of pliers) and seat both those bullets below 1.190" ?

******************
No. The magazine doesn't have anything to do with ejection or short recoil due to unbalanced spring load and power factor.
And forget trying to turn your parallel, early/abrupt release mag lips into tapered, late/gradual release. Most guns that are within spec do fine with the
early/abrupt release magazines. Some others do okay, but can have smoother feeding with the tapered variety. Some few that don't work well with the "Wadcutter" magazines can be turned completely around and feed flawlessly with the tapered hybrids and the USGI magazines without having to resort to expensive professional attention.
If your gun feeds and chambers with a pronounced
"Ka-Chunk" sound and feel...or if you get moderate to severe bullet setback...both on the top 2-3 rounds...the tapered/late/gradual release may be just what the doctor ordered.

i measured a round then chambered it several times and then remeasured. i'm not getting any setback. i also don't get a ka-chunk at all. the sound is fairly smooth.
for your listening pleasure, i've attached an audio recording of me chambering a round using slingshot with a brief pause between the pull and release
so i guess my gun is just one of the ones that work fine with the parallel early/abrupt mags. i was just hoping there was something i could do that would let me use a lighter spring

Light springs don't cause short recoil and failures to eject. Springs that are too heavy for the ammunition power level do that.
