    Sig Sauer magazines = Ed Brown magazines?

    Many months ago I tried the “Sig Sauer” brand of 8-round magazines. They are available in stainless steel only. When mine arrived I noticed the follower looked very much like it had been made by “Checkmate”. (More recently I discovered that “Ed Brown” brand magazines have the same follower as the "Sig Sauer" brand, with the same patent number.)

    I used the Sig Sauer magazines in my 1911s with flawless function on several range days. They are just a bit longer than standard magazines, which is probably why they will consistently seat in the magazine well when fully loaded and while the slides are closed.

    The only thing I didn’t like was the stainless steel finish. Just a little bit of bright metal was visible between the bottom of my 1911s and the pad on the magazine’s bottom. My 1911s are all either blued, parkerized, or black-oxide finish, so the exposed stainless steel clashes. More importantly the stainless steel will reflect if a light is on it, potentially giving away my location when otherwise in the dark.


    A few weeks ago I bought two “Ed Brown” magazines. These are stainless steel, with a black coating on the surface. The black finish seems extremely durable. My "Dremel" brand engraver, which works great on all my other magazines was barely adequate to engrave my name on the dark surface of the "Ed Brown" ones. Yesterday I tried these new “Ed Brown” mags at the range and was happy with the 100% function, as well as not having bright metal showing from the gun. I plan further testing with these magazines, in my other 1911s, and with various loads. If I become satisfied these mags will feed all the ammo I use from all of my 1911s I’ll certainly buy more.

    Check-Mate makes the OEM magazines for many 1911 manufacturers. Some will admit to it, others will not.

    They are both CheckMate mags.

    The only problem I've had with the black CheckMate's is they are a little thicker and very tight in a kydex pouch that fits stainless mags just right, and I don't find the black mags as slick as stainless mags, think follower moving within the tube.

    If you like them, Ed Brown has a mag exchange program.

    If you don't have to have SIGSauer or Ed Brown stamped on the mag, the CheckMate version (when in stock) is also available.

    That patent number on the follower tells the tale...

    When Sig Sauer started in the 1911 business, they made a lot of bold claims, about bringing 1911s to the 21st century, or moving away from century-old technology or other words to that effect...

    So it would be a bit weird if they admitted to using mags made by the same people making Colt's mags, no?
    Too many people miss the silver lining because they're expecting gold.

    Not really; the GSR was designed from its inception by Matt McLearn to use the highest quality components; initially they were comprsed of some of the best possible. Initially SIG used the Novak/ACT magazines, but when feed lip cracks became a systemic issue with them, they switched to Check-Mate 8 round hybrid feedlip extended tube with skirted and dimpled followers, with which they've remained for some 15+ years.

    Best, Jon

    I would not have guessed either CheckMate's hybrid feed lips (understanding hybrid lips have been around since at least the 1980's, but not with a CheckMate stamp on them), or their extended tube 8 rounders have been in production for 15 years.

    Thanks JTQ. I checked on Thunder Mountain's website and found the Checkmate cm45-8-b-h-ext was in inventory so I ordered two. They arrived yesterday, well cushioned within a sturdy shipping box. I compared those mags to the "Ed Brown" branded ones I had bought from Brownell's. I didn't see any significant differences.
    i sold all my handguns. . . . . . . . . . except for the 1911 style pistols in .45 ACP.
