These are the first mag extensions I've bought.
Sometimes you may have to seat the bullets back and forth with the palm of your hand but they functioned flawlessly. I ended buying more. Now my G19 doesn't feel like a toy.
I gave these a try on a new g19 build and holy shit there made like a tank but not overly heavy. 5+ rounds is very nice and unlike alot of mag extensions you can actually get 5 extra in the mag.
Easy to install with just one screw. The fit is snug even without installing the screw. Included springs feel sturdy. Customer service is by far the best I've dealt with. Punctual in response and friendly.
I prefer these over the most popular ones made by "TTI". These are: base price, about 10 bucks less than the tti, and more importantly, much more simple in its design. These use a singular, regularly sized screw that directly stops the extension from backing off the mag. Tti uses a set screw and pin, I feel these are a stronger, much simpler design. Dimensionally, these are very nearly the same as the tti however, so you shouldnt have any problems with fitting mags in pouches or on your belt if you already have the tti's
This is a high quality piece of kit. I've tried a few different mag extensions for my glock pattern mags and this is my favorite by far.
