Alright! So I got all the floor plates swapped out. First and foremost... I couldn't get the pull tab to press in on any of them. I ended up grabbing a awl (or a small flathead) and wedged it in each hole, popped the tab in and pushed it up, then did the other side and pulled the floor plate off. The I actually used a small flathead to pry the floor plate off the pull tab... that thing was all sorts of wedged on there... no wonder I couldn't get it to push in. Either way, the flush inserts fell right into the floor plate and then I just popped it back together. Definitely an odd design since but not that I know how to do it... no biggy. I still dont get the whole push the insert in the mag body, then press in tabs to release floor plate... that method damn near would take three hands to do.... small screwdriver seemed to do it well.
Overall, I think the floor plate design is pretty tough as long as you're not taking the mag apart every month... once locked in, I don't see how you can break it cause that bugger is IN there. Now if you take it apart alot, I can see the area below the tab holes cracking from having tools jabbed in there all the time or the tabs themselves rounding off. Kinda a none issue for me since I hardly ever take mags apart unless they actually need thorough.... like every 5 years! The body itself... definitely very thin-plastic feeling and Im not sure why they didn't run the fish scale texture all the way around the outside of the mag... that would make it feel REALLY good. The only area that looks weak to me are the feed lips actually. They're pretty thin like the mag body.... but unlike the mag body, theyll see alot more wear-n-tear as well as impacts when you drop the mag...heaven forbid you drop a full mag and it lands right on that corner. These things are super light though! I dont have a scale, but the damn thing feels lighter than an aluminum mag! I think itd be a much better seller if it just came with a one piece plastic floor plate and clipped in the same way it does now and none of that pull tab BS.
All in all, only time will tell. Im gonna load them up and go give them a function check and see how they work. Im sure theyll run wonderfully.... I definitely love the fact they stack flat (Main thing I DONT like about P-mags).
