Well built
So far i really like this mag-well it looks and feels good on my pistol... due to this crisis i haven't been able to shoot it yet that's the reason i gave it 4 stars hopefully ammo prices will come back down to earth soon
NEW NOV 2021 Design update
Rear of magwell internally changed to allow worn out bulged mags to drop free when empty or full.
Due to the G20/40 frame variances year to year it is recommended to use the SLR Glock 10mm Floor plate (Link Below)
Some frames will not allow easy mag retention in frame when using magwell. Frame to frame this can vary.
Our Glock 10mm Floor plates solve this issue.

Love it, however you can't use kriss vector 10mm magazines, the extension is just a little to high on the vector mag. But I used ghost Moab baseplate, Pearce +2, lone wolf +2, and slr +5 all with no problems. And of course stock 15 round work fine.

Perfect, snug fit. Looks cool and functions as it should. Great build quality as well. Hard to find a good magwell for the G21 gen4, but SLR delivers with this one. Quite impressed and satisfied with my purchase.
I have a long slide GLOCK and this completes the gun... easy to install and quick to do.. makes your grip better is it gives you extra support too plus makes it easier to load a mag into the gun..
Easy install, secure fit, feels great, works perfectly for my for the G20 gen4, also bought 2 more for the G44, and G19 gen5.
Extremely comfortable, and low profile. It’s like a teddy bear, I can’t put it down! Lol. Only one buyer suggestion... I paired this magwell with Moab magazine baseplates. Makes a world of difference over factory Glock baseplates. Awesome Product!!!!
Very nice product that fits just perfect,great customer service,thank you SLR rifle
Great quality, Perfect fit.
Works great. I installed it on-a Glock 21. It works great as advertised. This is the third handgun I have one attached. All work great. Would recommend this product.
This is my second magwell from SLR. the first was for my G19 Gen 5 with the half mood cutout. I loved it so much I purchased this one and plan on adding them to most of my glocks in the future. A+ fit and finish!
