97 Henning extended mag help

[210sandman]

So I bought a henning extended mag kit for my 97 mags and I’m having trouble, could only get 11, took it apart and replaced without the mag plate then only 10.  If you bought the henning 97 kit please divulge your experience, I googled and couldn’t find any pictures or videos anywhere- none 😭. 

Thanks in advance

So success for me was not using the base plate and rounding the sharp corners on the follower, I also added lube to the inside of the mag.

Cain has a video on there web sight, it was the only video I could find.  I haven’t figured out how to post pics here otherwise I’d share what I did. 

Henning is $40 and Cain $15.  FYI

Henning looks better but dang I don’t know about $25 a pop better


Any ways success, and cain has a video.
