Big Mouth Aluminum Magwell w/Brass Insert

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!!!

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.

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.

Picked this up in Gold for a Polymer80 G34 build.
Like many products designed for Glocks being used on P80's, the product requires some "custom fitting". I ordered the larger of the 2 brass inserts and had to grind down a good bit of it with my dremel to get it to slide into the bag of the P80 frame. I also had to sand down the rear corners of the P80 handle to get the screw hole to line up for the magwell to screw in to the insert.

I expect with the P80 that on some level there will be fitment issues so this did not deter me from buying this product. The weight and feel is great now that I got it on there.

Just a note of caution, it will fit on a P80 full size frame with some slight modifications to both the brass weight and the magwell. The lighter weight may fit better.

Beyond the cool custom look and the smooth reloading assistance it provides, the additional 4oz weight in the lower grip really balanced the feel of my G19. Especially on the last 3 or 4 shots!

This thing is outstanding, for speed loading, but also hand alignment and much more importantly to balance out the pistol that's otherwise extremely top-heavy. Went 4oz and couldn't be happier. Yeah, looks great too.

I purchased this magwell to replace the Magpul magwell that I was using. On my installation the set screw holes didn't line up perfectly -- meaning that I had to be exceedingly careful not to cross thread the fasteners. Once installed, there's a slight amount of slop at the front allowing the magwell to move perhaps 1/32" on the grip side. I have normal size hands, and on a Gen 3 G19, it starts to "cramp" the last two fingers on my right hand. I purchased the magwell with the 4oz. weight which now gives my G19 a more solid feel (think Sig). With a stock factory mag (no extension) you have to make sure that you follow through when inserting the mag since it gets "swalllowed" -- well past the bottom edge of the magwell. Overall, nice accessory.

Added this to my Glock 20 and it made a big difference in balancing the gun out. Installed in 5 minutes, no issues.

This is a great addition to my Glock 17 in running IDPA and USPSA matches. I am just getting into it and am using my old pistol until the new one comes. I would make a suggestion for the screw. For me it was a bit too long and caused the well to feel loose and move a bit. Not as solid as I would have liked. I purchased a new screw a 4-40 x 3/8 button head with the same allen tool size and now it fits solid and feels like part of the gun. The other items Is I had to wrap the brass weight with a piece of blue tape to give it a bit more of a snug but removeable fit.

I love the look and feel it gives and I can slam a mag and it goes where its supposed to.

Bottom Line is that this magwell not only looks great (especially if you are accenting with other upgrades of the same color) but anchors your pinky and palm right in the pocket of your grip. On the range, my grip is locked-in through multiple mags... not to mention the attention you'll draw on the line just from the wow factor.
My issue was the installation... the brass insert was not cut to fit into the half moon properly and the tapped hole for the set screw was off to the side. I was able to push the insert in and over to line the hole up, but then found that the hole was not tapped all the way and the set screw would not go in far enough to be recessed into the grip. After I tapped the hole (pretty easy since we are talking about brass), I was able to get the set screw in properly, but when you are paying almost $100 bucks for a machined part with one purpose, you expect it to be correct and an easy drop in.

I got one for my Gen5 Glock 19. The fit was perfect, I used Purple Loctite (Low-Strength) to ensure the screw don't back out over time from recoil. It does its job fine but, I chose it for two other reasons. First with-it being aluminum w/ brass insert, it adds more wight to the gun helping with control over it. Second is with my smaller hands along with the G19 pistol grip length. I'm able to sandwich my hands in-between the top shelf of the magwell, with the bottom of the trigger guard. This causes my hands to get pushed higher up the gun's frame, improving control. Making it pretty much impossible for my hands to slip around or off of the pistol grip.

Purchased for a G19 Gen3 build. As Lenny states in the video, fit is tight but perfect. It is recommended to take as much time as needed to install, don’t rush. Function of the device is perfect and assists in pushing the grip upwards for greater control. The aesthetics are perfect. In fact, a couple of RSOs and fellow shooters have inquired about the magwell and wanted to know the manufacturer. The color compliments the US flag design of the build. Lastly, the magwell accepts all Gen 3 15rd mags; OEM and custom builds with aluminum baseplates, thick and thin. Excellent quality and competitive price.

I bought one of these for my g19 gen 5 and it fits flawlessly. Works well with their extended magazines sold on this site plus it also works with standard glock mags too
