I have and have used them and find them to be a pretty good control, but since I don't like and continue not to train to drop my mags on the ground, I decided to not spend the money on them because I use my righthand thumb to disengage the magazine while I have my fingers and palm around the magazine taking it out. I than drop it in my pouch and load a new one with my righthand and release the bolt stop with my lefthand trigger finger.south paw said:Have you though of geting a ambi mag catch. I put one on all of mine works great.
It can be faster to just drop the mag on the ground of course and already have the other there to snap in, but I can load a new mag in my method very fast too and when it comes down to it I see magazines as something I've always felt you need to protect from being dropped on the ground to either be damaged, or lost or have to come back to later to get when there's always the chance you won't be able to.
For someone in these days at the range or in LE work there's less concern about that as they'll have time to and/or can replace them easy enough, but for me I look at it to continue to train and be better prepared for shtf where I might no be able to get more when I need them or at all.
The ambi safety and Badger Ordnance ambi charging handle is basically all I need in ambi controls.
