Got both my mags in the mail the other day. Cut the slot out of the back and pulled the rear plastic block out. I had an extended mag release coming in the mail but I wanted to try them out. Just a quick clip and they worked fine. Stuffed 25 rounds in the first time on both. Felt a little stiff toward the end of loading, but nothing serious. Emptied 25 rounds out of both with no issue.
Now I have my mag release in and there is lots of room. Thanks for the great service from hical.ca.
Here's a pic with the extended mag release in.
