You have to get really rough with it,don't worry it won't break.If you were here in Tulsa I'd do it for you,it takes about 2 seconds.I use my Glock tool but a punch will work.
Thanks for all the suggestions. I got one off. I think that the video would be a viral hit just for the language I was using!!
Tried the second one. Still a no go. Baseplate is still firmly attached, floorplate is tilted sideways in the mag and a two inch piece of metal dowel is in there somewhere.
Just so you don't think I've been easy on the mags. Or myself.
I think I'll stop for a while.
