Back in the 1980s I had an American made Walther PPk/S that would jam on firing the first round if the mag was removed and topped off. Another friend had one that did the same thing. If a full magazine was inserted and slide racked and then just carried or shot without topping off, it would 100%.
The PARA Elite 10mm I just bought has two Checkmate 9 round magazines that can not be inserted and locked home if the slide is in battery. Many 8 round .45 and 10 round .38 Super/9mm mags will do the same.
Since I also carry 5 and 6 shot revolvers having one more round in a 15 shot semi isn't something I am going to worry about. I do top off my 1911s just because I always have and they have always worked...but I don't use 1+ magazines either. 7+1 in a .45 and 9+1 in 9mm/Super.
