The Tripps I have work but they’re loose in the gun. They wiggle around.
You also can’t teacup hold them. The mag will bind on the bottom of the slide while firing causes jammage. If you keep from touching them they’ll work ok.
Because of that I recommend against Tripps.
Beware of Chinesium mags. There is a crap ton of them out there.
NEVER buy Pro-Mag.
Check Mate brand is spotty. I have some that run perfectly and some that are junk.
Wilsons are GTG.
I prefer Colt factory mags as they fit flush and have always worked well for me but they’re not 10rd.
