I am looking for magazine extensions for my Glocks. The manufacturers name is Enterprise Arms. They are or were out of California. I had some a few years ago and sold them not knowing I would probably never get any more. The company just does not stock them any more. They were +2 for .40's. They were a little shorter than the new Glock extensions and you did not need a floor plate at the bottom of the spring. You did not have to use thinner springs in them either. Anybody that might have any to sell please send me a private message.
