Best magazine release to date. - Rainier Arms MARS Magazine Advanced Release System for Glock

Perfect machining-Perfect finish-flawless operation. Holds the mag solidly and drops the mag the freely from both sides of the release. I only had to file a tiny bit from the holster on the right side. It works great although I haven’t tried shooting left/ reloading with my right hand. The mag releases better than the Glock OEM, Vickers TD and Crucible standard magazine releases. The crucible failed. You could pull a locked in mag out with a little tug. Vickers Tango Down was sluggish. OEM was just ok.
With this little Rainier gadget; the mags drop freely without having to tug/ rip them out. I have some extra mags in varied brands. No issues with ETS, Pmags, or OEM Glock mags gen 1-4. Training with this mag release has been both fun and a rewarding experience. I ordered a second one for my other gN4 Glock.
