Honestly, guys... I can sympathize with this guy. I dunno what the hell Glock is doing with their followers lately.
I have ten new hicaps for my 23 that I bought when the ban lifted. The last round was semi-stiff to load in all of them at first. Still is, and nothing that I tend to worry about. It's the last round after all. But I can do it readily by hand, no loader tool, and there is about two-three millimeters space that you can still depress the top round. Makes it real easy to seat the mag under a closed slide.
However. I just bought five more last week, and every single one of them is an absolute bitch to load. Even with the tool, i'm having to push down on the 13th round awful damned hard, and it's 'snapping' into place under the feedlips with an audible sound. At this point, there is no slop space left (you cannot compres the rounds down at all) and you have to practically pound the mag in to get it to seat under a closed slide.
This is not, in my opinion, right. No other pistol mags I have behave this way.
