PachmayrGrip Extender Black Glock Mid and Full Size 2 pk.

Perfect fit on my Gen 5 Glock 19 magazines. Easy install.

Good Quality

If you have big hands and want to feel like you have Better grip on your G19 or similar sub compact, this is amazing for a comfortable difference.

Cool

The media could not be loaded. These are so loose on my gen 1 that I can push them off with my thumb from the side. The gen 1 magazines I have are the ones that have round metal on the back of the magazine, just above the stamped .40. They fit perfectly on my later Glock 23 magazines, the ones that have flat metal across the back of the magazine above the .40.

I like these extenders so much I bought a second pack for the rest of my mags. Makes pulling them in and out extremely easy. I also like the way they look.

Because I'm a lefty with big handsAnd because I removed the finger-grooves to fit my large hands (so my fingers would rest more naturally on the grip)I wanted a little extra support at the base of the grip, and these do exactly thatInstalled in 5 minutes on both magazines - I expect even someone with little mechanical inclination could still do it in 15They fit well and match the black of the Glock just fineSlight wiggle will be noticeable due to play in the magazine, but is inconsequential

Unfortunately I was not able to actually try this product because it didn't fit my particular Glock. I posted a question yo see if it would fit my model, and got no response, so I went ahead and ordered it. I added a picture of the actual product as received so that maybe it'll help someone else in making a sound purchase.
