The Dawsons have been my favorite for sure.
I've tried Wilson and Tripp 10rd 9mm mags and even tried one of the Chip XP9's or whatever they call em.
The Dawson's are where it's at!
Got occasional failures to feed with Wilsons.
The Tripps would allow the top round in the mag to ride forward on the bottom of the slide, and then the mag wouldnt drop because that top round would hang up.
Dont recall what the snag was with the XP9, but I let it go too.
All of them are a little challenging to unload by hand, but thats not a big concern for me.
