Question: Will this fit the Glock 19 Gen 4? Thx
Document: Love them on my magazines for my Glock 19 Gen 3. Especially since I like to hold it two handed in weaver stance, give me a better grip, and feels as if it were molded to my hands.P.S.
This is a simple little product that extends the griping surface of the front of the gun&#8217;s grip. The product functions perfectly on my G23 Gen 4, and I am pleased with it. I chose this product for concealed carry because it adds minimal profile to the weapon.I do have one concern about the product due to its increased profile, but I have not tested it yet.
It will fit a Glock 19, but you will have to make some adjustments for the clip to fully lock into place in the pistol.
Perfect fit with my Glock 19, a little on the hard side for installation but doable. Now my weapon has a more tactical look and I have better grip and control on it.
Easy to replace and install. These grip extensions fit my Glock 19 perfectly and gave me the added comfort and grip support I was looking for.
AAAA used it on a kal tec 2000 9mm clock 19 clip I will be ordering 4 more adds the fight lengh to the klip
It's a real bear to get the bottom off of the magazine - I had to bring it to a gun shop - but once the extension is in place, it definitely makes my glock 19 fit much more comfortably in my hand.
As others mentioned, a bit difficult to get the original ones off, but it makes the 19 a perfect fit in my hand... I put one on all the mags.
For me personally this is not an issue since I only plan on using magazine it is installed on only in the gun, probably it will never be in a pouch.The product does come with a half moon insert that is used to fill a half moon gap on the front of the grip of some Glock models, such as the early G22 Gen 1 I used to own.
I cannot stand the half circle cut out in the Gen 3 and earlier Glock grips, so when I saw that this base plate would fill that gap was happy to order one. I installed the baseplate on one of my mags and inserted into firearm. It did fill the gap, but not completely flush. I went out and bought a magwell, which did the trick my more effectively
Answer: yes
