View Full Version : Stupid 1911 magazine questions

some 1911's list as 7+1 capacity (Springfield), while others list as 8+1 (colt/S&W). Do the 8+1's have a longer grip to fit the extra round, or it it just a function of the magazine?

If I buy a 7+1 pistol, and an 8+1 magazine, does it require some kind of blocking at the bottom of the magazine to mate properly into the grip when you load? (kind of like what you'd find in a 10 round magazine...) or does it mate up smoothly?

and, with a 10 round magazine, how pistol-specific are the plastic/rubber blocks at the base of the magazine? I assume they fit differently based on exactly how the mag well of your pistol is designed... but at the cost of some high end mags I'd like to think they work out of the box without adjustment...

Thanks...

You are good to go with both. Some say 7rnd cap because that's the mag it comes with. No difference in length

Sometimes, .45 caliber 8 round magazines are longer and stick out the bottom of the gun a little bit. Other than that there is no different and no modifications would be needed to use either in a 1911. Some 1911's are picky with magazines though, that is definitely something to think about.

Because the standard capacity for a 1911 is 7 rounds and has been that way for about 80 years.
Reliable 8 round magazines didn't come out until the 1990s.

How they get 8 rounds into a "7-round" magazine is to use a shorter follower and a magazine spring that allows it to be nested into itself. Even with that, it's very close to being in coil-bind.

If you make it a fraction of an inch longer, it greatly reduces the stress on the spring and magazine lips, improving the reliability of 8-round magazines.

The 7 rounders usually have a heavier spring and different follower.

8 rounders can be prone to first and last round jams because of geometry and spring strength.

If John Moses could have figured out how to achieve 100% reliability from an 8 rounder he would have. JMO.

I have some '7 rounders' that I noticed I can squeeze 8 rounds into. Is this ok? So far haven't had any misfeeds, but am I overstressing the parts?

Don't forget the hideous looking 10 rounders that are out there. From what I've seen at the range, they seem to work OK but they do poke out the bottom.

Yeah, those are what I was referencing in my OP... I have no issue with a magazine sticking out a bit too far, I just want to make sure it's reliable.

I don't care if the guy who kicks in my door to hurt my family has the last thought: "that magazine looks stupid". ;-)

Hmmmm, 2011 - 1911 = 100 years

Actually John Browning designed the 1911 in the early 1900's for the US government testing that started in 1907.

Ummm - no. The mags are the same length. The picture of the 8 rounder has a bumper on the bottom. You can see the end of the mag flush with the magwell.

In over 1000 rounds fired out of Wilson 47Ds I've yet to have a "last round jam" that wasn't my reloads fault - I've NEVER had a magazine related jam with factory ammo.

Just my .02 - 8 rounds are used in almost all 1911 style competition shooting games, and those guys run their guns much harder then nearly everyone else.

I'll put it this way and very clearly. My Colt 7 rounders are within 1/32" as my McCormick, Les Baer (which look like they are made by Wilson), and Wilson 47D 8 rounders (sans bumpers). Neither of them sticks out from my 4 1911s (3 Colts and a Les Baer).

The Wilson bottom is different in that in "crimps" on the bumper giving the illusion that it is longer, but it's not.

So sure - show me some pictures of longer 8 rounders. I'm curious now which brand it is.

Ahh - the guy who is always right on the internet. What I asked was for some comparison pics of 7 rounder and 8 rounders next to each other, or at least next to a ruler, sans base pads so we could see if they are actually longer. Perhaps Colts 7 rounders are longer then other brands. The basepad has nothing to do with the length of the actual magazine in what I'm discussing because a 7 rounder with a basepad would stick out. That was my only point about the basepads (which I must not have been clear about, because you missed it).

So perhaps you should "read before you post".

You missed the part where he says "Reliable 8 round magazines didn't come out until the 1990s."

1990s - 1911 = "about 80 years".


Some people feel that the 8 round magazine is not as reliable as a traditional 7 rounder, so they choose ultimate reliability over added capacity.

A seven or eight round mag with a flat metal base plate each will look the same.

The difference is in the follower, a 7 rounder will have a round follower, and is thought by some to be more reliable. I fall into this camp.

An eight round follower will be flat.

Go to the Metalform websight and look at some pictures.

I agree with this. I have shot my 1911 with both CMC and Wilsons and never had any issues with the magazines.

I dont mind 8 rounders but if I end up getting a 1911 soon, I'd prefer a few 7 rounders.

The top pic, with the 7 rounder, looks sorta like the old GI model ones that are very thing and simplistic. Did you get those through CDNN? I saw some place that had those GI ones that looked like that for under 10 bucks each. I've been hearing alot of people say they have great luck with them in terms of reliability.

Decided to stay consistent since both 7 or 8 round mags work. I tend to be a "shot counter" while shooting and wanted the same amount in all of my 1911 mags. Less change of doing a bonehead move and leaving a live round in. ;)

my 8rd magazine looks exactly as pictured, as does my 7 rd magazines. i went with 7 rd mags instead, because i like it flush at the bottom. i bought 20 gi flat mags, all of them work flawlessly.

You guys are comparing different mags. There are GI style flat bottom 7 and 8 round mags that are both flush. The 8 rounders pictured have a removable base that also functions as a base pad. Those stick out on purpose so its easier to seat the mag in place......

^^^This. The 7 & 8 round guts are interchangeable in the same tube. If you look at different websites you can actually order the same mag with or without basepad.

Wilson's new ETM mags have slightly longer tubes, which is supposed to be more ideal for 8 rounds. That said, I shoot those along with CMC Power Mags and Wilson 47Ds without any problems with any of them.
