    Do or will you offer ZMAGs blocked to 10 rounds for those of us in California?

  3. Jose says:

    Mags are great!! Used one on an M11/9 with a speed cube and it kept up no issue.

  4. Scott says:


    Received the mags less than two days after ordering, great shipping. Very impressed with quality and the fact it actually fit my receiver. Bought 10 promags and had to mill them all down to fit. Wish I would have had the opportunity to buy yours before I bought those crapy plastic ones. Keep up the good work. Interested in the 50 round ones, inform me when you have more.

      Thank you for writing. We are currently sold out of the 50-round ZMAGs. The price is $54.95 each with a $25 discount when you order six, and a $60 discount when you order 12. We expect to have more 50s in stock in mid to late July.

      Thank you again,

  7. Hello I recently bought a like new M11 9mm 86-ser # and it jams often. I have come to believe it is the plastic magazines, I am looking to go metal clips. I love what I have read in your comments section. But I read something about a 50 round clip for the M11 is that correct ? If so how much are they and will you have a package price like you do for the 30 round clips.

    Thanks for any info,
    P.S. Do you have an idea when you will be done with your wait list


    • marty says:

      Hello Bob,

      We are caught up on our waiting list. You can phone me at 801-815-5178 to place an order for the 50s.

      Thank you for writing,

    • John says:

      It’s probably because you’re using clips.

      • MR says:

        Reading comprehension….he’s using plastic MAGAZINES. He wants to GO TO clips. I’m not sure that Garand style en bloc clips will give him the desired results, though.
