I am looking at getting either the Beta-C 100 rounder or the 90 round "Snail" mag(clear plastic front)..anyone have any experience with these? Thanks!

They are both OK on a range. For other use, I don't rely on a magazine that needs a dry lubricant..

check out these guys. friends of mine down the road. bring your checkbook.

Looks like a reliable design. Good luck to him with this product.

I have fired the Beta. I would not want to use one for "serious" use.

Much better to have good quality 30 rounders.

The H&K ones I have used recently have worked 100%. [Several thousand rounds fired].
