Magazine wells have been around for decades as top competition shooters know that they not only help facilitate faster reloads but they also help you acquire and maintain a more consistent grip on the handgun. 

The more consistent your grip, the better your accuracy from shot to shot. Especially when you are shooting fast. 

The Big Mouth Magazine Well is machined in the USA from a solid bar of aluminum. Available in six different colors and two weights, 3 ounces and 4 ounces. It is the largest and most functional magazine well on the market and is used by top competition shooters worldwide!

Huge Difference


I recently added a G34 to my collection. The main reason I resisted Glock for years was the weight. I never felt truly comfortable with the lightness of the polymer frame. However, the addition of the 4 oz. magwell has not only added that weighty feel I was looking for, but it enhanced my grip on the handle. The insertion of magazines now is automatic. I picked up a 3 oz. magwell for Lil Sparrow's G19. She loves it as well and has added another dimension to her shooting proficiency. Double thumbs up!!!

G19 Magwell


High quality Magwell. Extra easy installation. Fits perfectly.

One small problem: it's too small for magazines with Taran tactical +5 extension. Otherwise all perfect.

Great Buy


I bought this for my 35 and it has helped me especially when doing a magazine change under time. Another great product for a reasonable price . Thanks Lenny.

A Little Too Tight


A must have to pair with the heavy base plate. The alignment is a little tricky though and leaves the Magwell pistol interface very tight such that I really have to slam the bottom of the base plate hard to engage the mag lock; I may need to machine the base plate a little to achieve a smoother insert with less force.

Regardless, this accessory and the thug plug definitely reduces felt recoil for my G20.
