cheap spare mags for STAR BM9

[xtriggerman]

A while back I posted a new purchase of mine at Buds of the Star BM9. A great buy for a all steel accurate mid size 9. Problem is spare mags are running about 35 bucks or more by the time you put shipping on them. I found that with a little tweeking, the Promag KAR 02 mags can run just fine in the BM. These 10 rounders need 2 things done to them to get them to work. 1) the body of the mag needs a very slight squeeze in a basic vise to reduce its thickness by about .008" . That will get the mag to be very nearly a drop free mag and still have a freely moving follower. 2) the slide stop step on the plastic follower needs about 1/16ths shaved off or else the slide will lock back with one round still in the mag. That's it. Center fire systems has these mags for $15.99 @ free shipping if you find $99 worth of an order.  Who doesent like cheap for a play toy?

Nice smithing...

Good job on modifying a mag that probably needs tweaking to begin with (according to the internet) to suit your totally unrelated application.
