Increasing capacity of 13-round Mec-Gar magazines.
 
There are two long depressions stamped in the sides of the lower portion of the 13-round magazines that is lacking in the 15-round magazines. If you drill a hole near the upper end of those depressions, with diameter the same as the width of the depressions, and also clip half the length off the two plastic studs on the bottom of the follower, the magazine will hold 14 rounds. I think it might be possible to further modify it to hold 15, but haven't really looked at that yet.

I'm not saying this is a good idea - just interesting.

Mark75H 11-24-2019 06:08 PM

I have altered all of mine to hold 14. There is no reason not to.

JimCunn 11-24-2019 07:18 PM

Have you looked at modifying for 15?

There have been stories about people dropping their modified HP magazines and having the rounds get all jumbled up. I'd sure test the notion out before carrying said magazines for self defense.
Best,
Rob

Couldn't one just buy the 15rd Mec-Gar for $22 or whatever?

Sure, but modding the half dozen or so 13 rounders lying around is free.

If you cannot hit what you are aiming at with the first 13 rounds one more is not going to help!

JimCunn 11-25-2019 04:16 PM

I understand. You are recommending that we go to 1-round magazines. 🙂
Sounds good to me.

My BHPs are range toys and I like the quality and reliability of my 13 rd mags, especially the mouse traps ones. I've got a few 20 rd Mec-Gar mags for fun.

I am happy leaving them the way they are. I do think it's cool that there is a clever mod. to add one or two rounds to the 13 rders.

Something wrong with Mec-Gar 15 rounders at $33.85? Or just do it because you can? I have one and it works just fine.

Poke around online. You should be able to find them for closer to $25.

I've got a bunch of 15-rounders. Since I've owned my Hi Power for fifty years, I've got a bunch of 13 and 10-rounders lying around too.

I've only been to a range twice in my life. Is there some benefit to them that eludes me? 🙂

If ya' get into a situation where 13 rounds ain't enough...ya' probably got problems bigger that what one more round is gonna' fix.

Ibmikey 12-04-2019 10:30 PM

When it comes to magazines and reliability McGar is the best and should be left alone... buy some 15 round mags and save the 13 round for the next assault on firearms, their owners and magazines by the left.

green papaya 12-04-2019 11:03 PM

I dont like to modify magazines, they are more reliably if left alone

I live in a a state where factory 13 rd mags cannot be replaced, not risking modifying a mag

KDKSAIL 12-04-2019 11:10 PM

....or the next actual lethal "..assault.." by some sociopath in a shopping mall, movie theater, school, etc. in a hoodie with cargo-pants pockets full of 25, 30, 50 round magazines. '..left..', 'right' or dead 'center' doesn't matter one little bit when the '..body count..' and casualty list is provided by local law enforcement at the post-incident press conference.

I don't even travel through states like that.... 🙂

On my Kimbers, I usually have to modify the durn things just to get them to feed reliably. A mixed blessing - I use that as an opportunity to add a round to them as well.

As far as round count, I'm also quite content with my 5-round J-frames.

Mark75H 12-06-2019 06:49 PM

There is no reliability penalty with increasing the 13's to 14. The difference between the 13 and 15 is only the special hollow follower in the 15.

KDKSAIL 12-06-2019 08:40 PM

I suppose that what it comes down to is; '..just 'cause I feel like it..'...in which case...go fer' it.

BUT....when shortening the '..legs..' of the original magazine feed/follower, make sure the angle of feed remains un-changed.

Just so happens I have a BHSS gauge for maintaining the proper angle....I can loan it if someone runs into trouble.

KDKSAIL 12-07-2019 10:25 AM

Just as a curiosity....Does Meg-Gar sell replacement '..hollow..' feed-followers used in their 15 round Hi Power magazines. If so...purchasing a 'hollow' 15 round follower to replace the '..footed..' 13 round follower might be the more prudent modification to increase mag capacity (??)

JimCunn 12-07-2019 10:40 AM

If not available, they could be 3D printed.

Donny 12-08-2019 06:30 AM

As with many topics on firearm forums there exists a variety of opinions and strong feelings. We've all enjoyed a good discussion. I've enjoyed learning about about the mod procedures, if I ever decide I need an extra round or two in my range toys.

PsychoSword 12-17-2019 11:50 PM

What would a firearms accessory or firearms modification thread be without stupid platitudes about not needing this or not needing that, or if you really need this, than that won't help you a whole lot. :barf:

So my two cents is.. I have the 15rd Mec-Gar mags, and they generally work great. But in my experience with an older Hi-Power (Pre-MKII) they tended to lock the slide back early. Not so on the MKIII. And I have heard of rounds in those mags getting jumbled around when dropped, but not personally experienced it. However I have experienced it with other quality mags that seemed to have a little bit higher spring compression than they should have. My question is, does this modification to the 13rd magazines compress the spring beyond normal specs when you load 14rd? And how stable is the shelf of the top of the spring on the follower above it when you cut down the legs?
