No issues. - Shield Arms S15 Gen 3 Glock 48/43X 15 Round Flush 9mm Luger Pistol Magazine

Despite what some say, you CAN use the factory mag release-- HOWEVER the metal mags will eat up the platic release rather quickly, so its best to replace the magazine release with the shild arms metal release right away.
The starter kit with three mags and a release replacement is a good deal. I rrally liked the g48 alot but strongly disliked the 10 round capacity. This puts you to 15 with options to extend to 20.
Super easy to replace the release. Took 5 minutes, most of that fiddling around.

Make you 48 worth carrying. Get these.
