    Welding 2 mags together....Who did it?

    I seen a post on here before that someone did this. How does it run and how did you do it? I would like to try it myself to increase the round count... Thanks in advance. BTW, I have a MAC-10/9 with an UZI conversion.

    I made one and it works great. The key is to slightly taper the ends where the mags meet so that the bottom section fits up into the upper section. This will (should) prevent the rounds from binding as they are pushed up through the junction. I spot welded it in several places since I have a cheap flux core wire welder and didn't want to burn through the mags.

    Get the long mag springs from USMACHINEGUN.

    I have two that i bought from a member here.
    One runs like a top, 57rds with either the stock upper or the MAX11.
    The other mag has a burr that i can not reach with any tool i own. I have a few ideas for that problem. It will only run about 3/4 of the mag.

    The springs are just two stock PAM2 mags brazzed together.

    Have one...it sucked.

    Sent it back. Still sucks.

    I own 100's of mags and have made every one of them (except the ones I threw away ) work for the Uzi, M10 .45, M10 9mm, M11, etc and this one mag refuses to function despite my efforts

    I see it on the shelf in the boom room and wonder why I keep it around.

    So far It's 50/50. You up for a challenge?

    i tried soldiering two springs together and they always fell apart. I prefer the single, longer replacement springs.

    Hell ya, I'm up for the challenge. I have a wire welder so it should work just fine. I will order that extended spring and go from there. Did the spring have to be shortened any or slap it in there just as is and how many rounds can I stick in there if I put 2 of the 32 round mags together? Thanks... this should be fun to blast

    Mine is shorter and runs 45 successfuly, but I could cram 50 in it. You might get 60 in two mags, but the longer they are, the harder they are to get running.

    Why settle for 36 rounds of 9mm.....


    ... When you can have 110 rounds?!

    I did one recently, 2 Sten mags for my Sten converted M11/9. It runs excellent, haven't had any issues with it yet, even with a Mac Jack. Mine was Tig welded. I used the 2 springs held together with an electrical crimp connector, no mods to the springs.
