convert Colt 1911 7 bullet mag to 8 bullet?


December 22, 2008, 09:18 PM
I have the stainless "Colt" .45 brand magazine that came with my stainless colt 1991 commander and it holds 7 bullets. I bought a blued mag that holds 8. I took the followers out of both of them. can I alter the one in my 7 shot, machine of that long tab on the bottom of the follower, to make it an 8 shot? there is a slight difference in the look of the followers. Has anyone ever altered a follower to hold more bullets and it still function propperly? Im about to do it. If it works or not Ill post the results. I would buy one but I cant find a "Colt" brand stainless in 8 round without the plastic extender on the bottom which I really dont like. So if I screw it up Ill just buy another 7 round.

I think you'll find that that long tab is what keeps the follower from doing a "nose dive" when it's trying to lift the slide release after the last round.

Chip McCormick has a (patented?) design for his V-shaped follower that permits loading 8 rds in a conventional 7 rd magazine. He sells a conversion kit for $15, which is a little cheaper than the entire CMC magazine. Also, it lets you have a magazine that says "Colt" on the bottom.

I don't like the design, but a lot of shooters think they are great.

Here's a link to Chip McCormick -

Leave it along I have yet to have a relieable 8 round mag . I can't really see the need for 1 more round.

I carry with a Kimber branded 8 rounder, and I've never had a problem, but I'm about to switch to some CMs.

Is it REALLY so bad to just BUY one?

I've tried the conversion kits and various shortened follower designs. They might work for some, but I have abandoned them all for high quality 8 round Power Mags from Chip McCormick.

Don't do it....look, if you are dead set on having another 8 rd mag and don't want the 7 rd Colt mag anymore and it's still in "like new" condition, just send it to me and I'll send you a new Wilson Combat 8 rd mag still in the the very least, let me send you an 8 rd follower and you send me the 7rd one....

John Browning designed the 7-round mag that way for a reason.

The most important reason being, that it is impossible to over-compress the spring and weaken it.

Even if left fully loaded for a lifetime.

Cut the follower to hold an unneeded extra round, and all bets are off.

thats the answer I was looking for. I didnt cut mine yet, and wont now, I have a black 8 round but it has no name what so ever on it. It seems to work well thus far. I keep it in my car as an extra.
