if i'm not mistaken, the difference in
the later and earlier mags is that the
later mags have a slot in the side that
engages a projection in the magazine well
that the earlier firearms do not.
i tried back several months ago to find some
795 magazines and everyone had them
backordered. i had found a small gun shop
that had some that looked the same
that were new, but unpackaged for i
think it was 5.00 each or so. i figured
out the ones i bought wouldn't seat in
the magazine well because of the projection.
i disassembled the mags and cut a slot
with a dremel and wheel using the one
mag i had as a guide. a little touch-up
blue and i was good to go.
(what did folks do pre-dremel tool?
