Gen 4, 5 Magazine Release Extension
Installation was a breeze. It turned my 19 Gen 5 from a range-only pistol to one ready for tactical employment, from a two-handed magazine release endeavor to a smooth one-hand release. My confidence in changing mags quickly and efficiently went from a zero to sky-high.
I recommend it.
This product is just what I needed. I have small paws and was unable to reach the factory magazine release without shifting my grip. But I no longer have that issue after installing the MCarbo mag release. This button sticks out much further and seems to require slightly less force to drop the mag. This improved geometry is a plus for me. It fits in the frame perfectly, and has good texture. Worth the price.
Should of done it sooner!
I just started getting into competition shooting and the ext mag release has made a huge difference!
Great mag release
Had difficulty consistently getting the factory mag release. With my Glock 47. This one makes it easy. Doesn’t stick out too far and has great texturing!
Good move getting this
Put this off long enough and got it. Easy install. I also got the notched spring tool and that made seating the spring a breeze. I have some modified pick tools for grabbing springs n things like this spring that made removal/install of the new latch a breeze. 5 min is all ya need and it's well worth the effort. Got big hands and the latch is just that tad bit more above the surface and quicker to release.
Total Quality
Quality, not only in service but with everything thing I have ordered from MCARBO. The extended mag release fits and works perfectly. For my sub 200; the trigger upgrade has made it a pleasure to shot as with all the other parts I have ordered. Will continue to order again from MCARBO.

Worth it
Took about 3 minutes to install. Perfect instructions! This adds just enough of an extension to make mag changes with gloves easy. Doesn't interfere with any of my IWB holsters. Always quality products with these gents!
Have yall tried it on gen 6?
Will this work on a glock 47
Yes, this should fit without issue.
The extended magazine release is designed for Glock Gen 4–5 pistols, and the Glock 47 falls within that compatibility range.

Would this be compatible with the Shadow Systems MR920P? Thanks!
Yes — the Shadow Systems MR920P uses Glock 19 Gen 4–style frame geometry and magazine catch parts, so our Extended Magazine Release for Glock Gen 4–5 Pistols will fit and function in the MR920P.

Yes that will work on the SS MR920P the frames are similar in design so you should be able to use it.
Will it work with the G44?
No, the Glock Gen 4-5 Extended Magazine Release does not fit or function properly in the G44.

hallo können sie dieser artikel ach nach schweiz versenden?
Leider versenden wir nicht international. Unsere internationalen Bestellungen finden Sie unten auf der Website unter „Informationen und Richtlinien“.
will this work on a psa Dagger?
It won't work. Dagger uses gen 3
Can you make one that is truly ambidextrous, instead of needing to be switched? A button on both sides so a righty and a lefty can use the same pistol. The slide lock is on both sides on a Gen 5; like that.
It might be possible to make, but the internal area of the mag catch spring are is not intended for it.
