A little late, this might've helped
yes, a bit too late....but i watched the wilson video...
what happened in my case was, that after i got the slide release to come out of the 1st hole, the control unit "somehow" moved forward. when that happened, not that slide release "locked" int to control unit since the remaining holes now, did NOT line up, for a quick removal.
i had to "gently" tap the control unit back towards the grip, when that was done, NOW, the slide release came out as quick as in your video.
for the life of me however, i just could not at first "see" what the hang up was. more importantly, is i have no idea why that control unit moved forward in the first place.
then, that insipid TINY %$#**&^# mag catch spring would NOT stay in place.
so my "fix" to make it stay in place was some grease on it, where it rests in the mag catch button.
so, as you can now "see", it was NOT a 10 minute job like someone here said it was......
otherwise, in all frankness, if all went well for me from the get go, it most likely would have taken me 20 minutes to do this....
so, that extra 40 minutes i cursed
@Belt Fed for saying it was "Only 10 minutes" was 40 minutes taken away from my 2nd afternoon nappy time....
BLASTED @Belt Fed ....!!!!!!!!!!
