Okay, my Springfield Armory TRP came with 2 7-round mags. What is the difference between 7 round mags and 8 round mags? I'm thinking of some Wilson combat magazines in the 8 and 10-round capacity. Any ones I should skip?

The 7 rounders hold 7 rounds and the 8 rounders hold 8 rounds.

try a couple of different mags to see what your gun likes. My 1911`s like the cheapo $7 mags. But the same mags in a friends 1911 and it hates them.

I've seen 15 round single stack mags at PA gun shows, they stick out the bottom about 6" or so. At first glance it looks like another illegal mag that you see at the shows over there, but in this case it's good to go.

Ray, I have four of the Wilson Combat 8 rounders, for my Loaded Springfield. Haven't had an issue yet.

I like wilson combat. lately I've been buying chip mccormick 8 round mags. they work great in my colt.

I was going to say 1 round..

 

Harry

these are the ones i ordered and work great in all my .45's..

I also have chip mcormick shooting star 8 rounders also work no probs and 10 round chip mcormicks also work no probs.

I've heard nothing but bad things about the 15 round 1911 mags so I'll pass on those. I had some Chip McCormics and Wilson Combat mags for my first 1911 so I think I'll stick with those.

 

I was curious as to why some don't use 8 rounders. If I recall, it's due to the 8th round pushing up on the slide. So they use the original 7 rounders. Is that true or internet lure.

Ray, I use Ed Brown 8packs without issue. If you would like, send me your address and I will mail you two of them for T&E. Providing of course you send them back in short order and clean.

Thanks Jack, do they have the base pads? My 1911 has the magwell that is unfriendly to the standard base plate mags.

Wilson Combat and Tripp Cobramag magazines are both excellent products. They cost a little more then the others but are worth it IMHO.

Ordered some chip McCormick 8 rounders, blued, with the base pads. And 1 chip McCormick 10 rounder for sh1ts and giggles. I'll pick up some Wilson Combat mags next payday.

 

I'll ask again, why the difference between 7 or 8 rounders?

I have a McCormick Shooting Star 8 round and it works great; it's every bit as reliable as the 7 round SA mags. A 1911 with a total of 9 rounds is nothing to shake a stick at.

 

To answer your question, the witness holes and the follower are different. Not sure about the spring (its probably different too).

8 rounders have a diffrent spring and follower to squeeze that last round in..

 

the chip mcormick 8 rounders are good mags..

Wilson, Tripp, & McCormick in that order.

I have used them all in my Trojan and Nowlin Crusader. Wilson's have a LIFETIME guarantee. Plus all the hardcore ninjas use them.

47DE for 8 Rounders in 45acp. 47NX for 40s&w/10mm

The Bureaucrat for 45acp 10 Rounders.

Tripp for 40s&w/10mm 10 rounders.

My Springfield came with 7 rounders, just sayin

I've heard nothing but bad things about the 15 round 1911 mags so I'll pass on those.

I couldn't tell ya, I don't have any and never tried them. Either way, they're not very practical anyway.

What you will find in 1911's is that the 1911 in use, ramped, non ramped, ammo type, and caliber all play a part in which mags it works best with. I have tried most 8 rounders out there. Right now I am running Certac mags in my 5" GM non ramped. They have been the best so far.

Different guns like different heads, no matter what mag is in the gun. Make sure you try your ammo in a friend's mag with your gun, then buy those mags.

 

As far as 8 or 10 rounders, depends on what games you want to play......USPSA L-10 Division uses 10 rounders, Single-Stack uses 8 rounds in a mag and so does IDPA in their CDP Division. 7-round mags get relegated to the junk drawer at my house--unless they're for my Officer's .45 (smaller mag, same follower as 8-rounder) so it can bark with 7+1 in the tube.

If by "heads" you mean the projectile its self, the mag matters more depending on the projectile being used!

I don't think you guys are understanding my question. What is the difference between 7 rounders and 8 rounders? Some full size guns come with 7 round magazines and some come with 8 rounders. So why?

IF they worked, they would be cool for a 2x4 shoot.

Ray, the original magazines for the 1911 had the seven rounders. Many of the more classic/less tactical 1911s still use them. My Colt Series 70 Repro came with two seven rounders.

I believe there used to be (i.e. issue has been resolved though) reliability issues with 8 rounders. I don't know if it was that the extra round made it harder for bullets to be stripped from the mag as the slide went into battery, the different feed angle of the follower on the 8 round mags, or the different springs used in 8 round mags. I have seen mention of all of them, but this being the interwebs, don't know which (if any) were legitimate causes. As for current 1911 models, I personally go with 8 rounders from high quality manufacturers. I have yet to get a misfeed from my Chip McCormicks.

More capacity = better. That's why.

 

As to what differs, it is usually some combination of differing length of the magazine, different follower design, and different feed lip geometry.

 

Most 8 rounders do not fit flush, but occupy the space a 7 rounder with a base pad would. They use the space a base pad would take up with more mag tube, and then have some form or wrap around base pad.This is generally not a bad thing because in the event of a failure, you have a protuberance to grab onto and rip the magazine out by sheer force.

 

A GI 7 rounder is definitely cheaper to manufacture.

 

In general, Tripp (aka corbramag), wilson, chip Mc Cormick, and metalform make good stuff with some exceptions.

 

First, the exceptions that I know of (things I wouldn't buy):

 

1) The wilson combat 10 rounders. They seem real nice, but without the metal stop welded on the front, you can overinsert them. The welded on bit seems sturdy, but I've seen more than I'd like have that bit sheared off when used a lot in competition. CMC 10 round power mags are cheaper, and the polymer base pad that serves to limit insertion is, surprisingly, more durable. (as are the bases on the tripp mags).

 

2) MEtalform flush fit 8 rounders. These use a follower that is almost exactly like a government split foot design, but with a shorter tail. This makes it less stable than a 7 round GI design, and when you step out of the realm of 230gr round nose FMJ, the GI design is already marginal at best.

 

Things that are worth noting

 

1) CMC powermags have kind of soft steel for the lips. They may not come perfect from the factory, and may require maintenance.

 

2) CMC powermags cna have issues with some mag wells. Basically, the part of the base pad that stops over insertion may be a hair too wide for the gap on some magwells. 2 minutes with a razor blade to narrow that bit will fix this without much headache.

 

3) Wilson polymer followers can have the slide lock chew up the shelf on the follower with lots of use. The old orange followers were pretty bad with this, I don't know about the newer black ones, but since they likely aren't harder than steel, I'm guessing the duty cycle on them is just longer. The orange ones looked like they were polyethelene or something similar form the way they wore. I think the newer ones are delrin.

 

4) Tripp mags are designed to let the bullet sit a bit higher up in the gun. Most guns this is a good thing and allows better feeding of more bullet profiles. On a small minority of guns this can cause issues with feeding.

 

Myself, I just buy tripp mags these days although I have a bunch of CMC mags and a few metalforms.

 

The checkmates look a lot like some of the above mags (tripp), but people seem to have issues with them. I suspect the tubes either aren't as rigid, or the QC on tube dimensions is less and thus reliability goes to crap.

Wow, thanks for the info guys. I'm gonna stick with the Chip McCormicks and Wilson Combat magazines. Those seem to be the most popular and reliable. And 8 rounders too, even though my TRP came with 7 rounders.

Don't put too much thought into what your gun came with.

Put thought into what you will be using.

Personally, if I was going to spend what the wilsons cost, I'd buy the tripps. They are VERY nice magazines, and they work in my SA without issue. At the moment, I don't know how that would go. Virgil's house burned down in the texas wild fires a couple days ago. Last I heard the business was intact, but I'm sure things are going to be out of whack.

Just got the 2 loaner mags from Totalabuse, they are nice!
