I have both a Wilson and Kimber magazine. The Wilson is nice but needs a bit of force to seat it fully with eight rounds. The Kimber, also an eight round, won't seat at all unless there are seven or fewer rounds in it. The Para mags pop right in fully loaded.
I'll take a guess and say the mags are near new or haven't been used much. I load all my new mags full and stack 'em up on the bench for a while until softened up.
