I have a uplula-k (do a google search)
and it works great on kahr,1911,1911 22 conversion,cz,cz kadet,witness (45) S&W 59 series, mags
it was the best 40 bucks I spent on a accessory, and saved my thumbs loading the pesky cz kadet mags..
it does not like the sharply angled 22 mags like a mkiii, and buckmark style but standard upright mags its great..
I know you said a baby eagle in 45, but the closest I have used it with is a witness 45..and it works great
