The SLR Rifleworks Glock 20/21 Gen 5 Magwell is purpose-built to enhance reload consistency on full-size Gen 5 Glock 20 and 21 pistols. Machined from durable 7075 billet aluminum, this low-profile magwell subtly flares the magazine opening to guide magazines into place while maintaining a clean, factory-like profile on the grip.

Designed for frames run without a backstrap, this magwell works with standard 13-round magazines as well as SLR floor plates and SLR magazine extensions. It is ideal for range use, training, and competition where smooth, repeatable reloads matter, and it integrates seamlessly with the pistol’s ergonomics. SLR Rifleworks is known for precise machining and thoughtful design that complement modern handgun platforms.
