Anyone ever use these for the taurus PT 92? I found a few for $5 each. Thought they might make good range mags but do they fit and feed O.K.?

I've never heard anything bad about any Ram-line product. At that low price you can afford to take a chance, IMO.

When clean, they seem to work ok.
The ones I have, I think, hold 17 rounds and they use a unique follower that contains the spring...kind of like a tape measurer.
That makes them harder to clean.
A kerosene/solvent soak while moving the follower in and out is about all you can do in cleaning the follower.
They work even with the base pad removed.
The mag bodies seem to have a good heat treatment, so if the feeding system ever does go sour, you can (I have) drill out the rivet holding the spring and add a follower, spring and baseplate from a 10 rounder (may have to be a bit innovative here) and continue using it as a high cap.
In other words, don't toss out the bodies, there are salvagable.
