The Strike Industries G42 Magazine Extension is a low drag/no snag design which allows for fast magazine reloads every time! The SI magazine extension adds 2 extra rounds to the G42 magazine! The extended grip on the extension allows for extra surface area and gives the shooter better control and increased grip. The added ergonomics of the magazine extension leads to a higher accuracy potential

Really Plus 1 but still a good product.
I have this on my Glock 42 magazines and they look great and give the right amount of pinky extension as well as getting an extra round in the magazine. Yes "an" as in one. I don't see how you can possibly get an 8th round in it. Still an extra round with the nice looking checkered extension is a plus, Especially for the price.

Easy Install & Better Feel
Easy install and now I can get a whole hand on the grip. Have not hit the range to test these out yet but so far so good.
