    Mag Well

    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.

    G20 Gen 4 Magwell

    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!

    Glock Gen 4 G20/40 Magwell

    So far, the item I received appears to be of exceptional machining quality. The opening is wide enough to assist with reloading, but narrow enough to not be obtrusive. The only slight complaint I would have is that there is some slight play to the magwell due to the single point of attachment.

    Glock 20 magwell

    Finding 10mm aftermarket add ons that work are hard to find. The magwell combined with the mag extensions is an awesome combo and makes reloads much easier.

    Glock 21 magwell

    Attention to detail is there! There isn’t much out there for us G21 guys but this is it anyway. Buy the mag extension too it works perfectly with the magwell.

    Sleek G20 magwell

    Wanted a slim magwell for my G20 gen 4 and this definitely fits the bill. Installation was easy without any need for alterations. Fit and finish were top notch and I'm very happy I went with this. Highly recommended!!

    Gen4 G21/41 magwell

    excellent fit, I purchased on for my G45 and liked it so much I bought one for my G21. If you have bigger hands it really improves the feel.
