I was surprised that when I load the mags to the specified capacity., I'm unable to rack the slide.
Never had a gun do that...

Both my 5” and X-Comp were like that, they were 15 round guns, not 15 + 1.

Not a proper with my mags. Yes it is stiff but I carry 15 +1 all of the time. I think it has gotten better with time.
