M52 Mag Enlargement?

[Drm50]

I’ve herd talk of modification of 52mags to hold 7 rds. Any truth to this. I have a couple mag housings with no follower or spring. I wouldn’t risk a got mag when they been going north of $100 and show no signs of letting off.
Anyone seen any articles on this that weren’t from Bubba and company?

When I bought my Model 52-2 it came with several extra magazines. One of them had been modified to hold 6 rounds. This was done by lengthening the slot that the follower cross pin rides down the side of the mag body and moving it back slightly as well to allow for the stacking of the rims. And a tiny bit is relieved from the follower, i forget if at the front or rear.

It works fine but when I take the gun to the range I just load it with 5 rounds anyway. I have never heard of a 7 round modification and doubt that there is enough room in the mag to allow 7 rounds and still compress the spring. Here's a couple of pics.

I posted a small note on modifying the mags some time ago.
I have dozens of mags modified to hold 6 rounds. Most work a treat. The one or two that don't the slot was opened to wide allowing the follower pin to twist.

I have modded several to hold 6. I don't think you can do 7, but never tried. The 6 round mags were done to shoot PPC, which has 6 shot strings.

The way I found to work the best is to not follow the original slot, but go straight down from the bottom of the slot, parallel to the front and back of the magazine. This does not "Bubba" them, and they are reliable.

One of my buddies has a 6-round modified and it works. It's the first one I've come across.

For a decade I've hoped someone would offer a stash of these modified magazines for a deep discount as altered but I never see them offered.

If Triple-K does actually introduce a 52 magazine as we discussed a week ago, those would be a good test mule for 6 or 7 rounds.
