Great Service

Haven't been able to use yet, but have always had a great experience in ordering from this company. Items arrive expeditiously.

Pain in the ass to load

This magazine didn't fit well in my FN 509. It rattled and I didn't trust a loose magazine

Promag FN 509 9mm 50 Round Drum Magazine

Good

After breaking in the mag, it performs fine. I had little hiccups the first couple chamberings but it quickly resolved it self and started functioning properly. Also my ambi mag release for the 509T full size it doesn’t work with the left side mag release only with the right. I don’t know why, it’s pretty weird but it’s not a big issue since it’s a range mag.
