Almost, but not quite…
Not quite, for me, that is. I’m an owner of a Mark I that I really, really like (owned since in the mid-1960’s). Problem is, a 9 crtg magazine, of which I own two. Been wanting a couple 10-rounders, for bowling pin, steel plate challenge, etc. Verbiage on this product said it would add one round for the “Mark Series” and the “22/45”. I should have trusted my instinct, when I KNOW the Mk I mag is different from the Mk II, etc. But, I said, surely the manufacturer knows what he’s making. So, I ordered the packet. And, NO, this does not fit the Mk I mag! Oh well, said I, next time… etc. So, thanks anyway, but this one is a no-go on the Mark I! But, it should work GREAT ON the Mark’s II, III, IV, and probably the 22/45, as well. ☺️
