Left stock plates on spring, put in a small spacer (home made)with a hole in it to clear button on stock plate, using these under spacer. For loading to 10 it gives me a bit more spring pressure to push up the first round, am hoping that will improve the feeding reliability with the occasional slide lock reload.

Did you break a factory floor plate during dryfire? I did and being too cheap to buy factory, I gave this a try. To my surprise and satisfaction, these work with Henning base pads as well.

Have a couple basepads that are honery about latching up with the stock (flat) plate. Cone shaped plunger on these fixes that.

I have springer precision pads that I wanted to put on my sp01 mags that came with the +2 pads. These are much cheaper than the mecgar locking plates I needed, and they seem to work just as well, holding the pad in place, even though I think these were designed for shockbottle pads only.

I'm running these with the shock bottle basepads which by themselves are great. However, since I don't have ball point pen finger tips, removal of the pads during a match for quick cleaning, for sand or tiny boulder removal just stinks cuz I either don't like taking the time (being that guy who doesn't do anything to help the squad) or hardly ever have "table space" required for surgery. With these plates I can pop off the pad easily and do a quick clean of any mag while standing anywhere. Whether you agree or not with how much time you're ok with taking addressing your post run/set up for next stage loading here's a great example... at my last local match due to circumstances we wound up with a squad of 8 quickly after a first stage DQ to a shooter and one other guy switched squads. The DQ guy left and myself and 3 other shooters were the only ones capable of doing "RO" duties. I had little to no time to do anything other than load quickly after shooting. With these plates on numerous occasions I was able to clear a bunch of small rocks and dirt extremely fast and thus had no equipment issues. Quite a long post for a 2$ item I know but if you read reviews like me you want to know why and how something earned it's great rating. These are a must have!
