Big Mouth Aluminum Magwell w/Brass Insert
Ratings & Reviews
by Big Falcon
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.
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.
Works on P80 with some minor modifications!!
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.
IO just recently got one of these for my Glock 17 and I'm asking myself why didn't I do it sooner. It added weight to the back end of the gun and a better grip on the gun. Now I know! Thanks Glock Store for the service and the parts.
Smooth reloading and overall balance
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.
A Few Concerns But Purchasing Another
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.
Glock 20 install.
Added this to my Glock 20 and it made a big difference in balancing the gun out. Installed in 5 minutes, no issues.
