Magazine Advanced Release System (MARS) for Glocks
Ratings & Reviews
Love it! Works flawlessly in gen 3 G17. Looks cool, has extended button for right hand thumb release and is easy to activate with your index finger on either side. It is a little hard to activate the release with your thumb on the left hand but it gives you options. I'd recommend it.
Rainier Arms MARS
I recently purchased a MARS unit for my Gen 3 Glock. I am a Lefty and I LOVE this thing !!! I release the magazine with my left index finger but this unit operates MUCH MORE positively than a polymer mag release. I would definitely buy one again.
No brainer, GET ONE!
This should be the release that comes from the factory. 110% improvement over stock mag releases. It’s a no brainer upgrade.

Love this thing! Made a huge difference in my being able to release an empty magazine. Do not have to change my grip anymore. Also took less than 10 minutes to install.
MARS release extends perfection!
I read the reviews so I installed two of the for a friend they work excellent. So whether your right or left handed this mag release compliments both right and left handed shooters!The best I've seen so far!
This things is everything it's advertised to be! I can quickly and reliably drop mags with either hand and on either side of the gun. Solid and well-built too. Easy install.
Need these for more pistols

Need to make for Glock 21 and 30 please, love them on other Glocks I own.
Perfect for Ambidextrous or left -hand positioning. I'd advise this over the extended Mag Release
I have 2 G23 Gen4s. I use this on one of them. I love the ambidextrous aspects of the MARS system. I'm right-handed, but do some things with my left when multi-tasking. So overall this is really helpful because it allows me to consider doing the same with my gun. If my RH is ever unavailable, I can always shoot lefty with the one that has MARS. I would recommend making this with colors. It would fit nice in areas where users want to style their guns.
Good product still hard to use left thumb to manipulate.
Got it for my G17 long slide. As a lefty it’s Easier to manipulate with the index finger and doesn’t dig in to your trigger finger. My only gripe is it’s hard to push the Ambi side of the release. If it stuck out a little more to give leverage it would be perfect.
MUST GET UPGRADE!!!
Been waiting to get this for a minute, was able to finally pull the trigger on it. Absolutely crucial upgrade in my opinion. Being able to transition to using the trigger finger on my strong hand instead of having to manipulate the firearm to use the thumb release shaves off precious time in reloading. It's comfortable and after just a few minutes of drills I was beating my previous times on reloading. It just felt natural.
Not sure what it is but the Glock mag wouldn’t lock in unless I really jam it in. I also have an agency arms magwell.
