ATI Schmeisser S50 MLE Magazine Adapter for Glock 17/19 9mm 50rd

The ATI Schmeisser S50 MLE is a magazine adapter, not a complete magazine. It installs on a Glock 9mm magazine you already own and takes a Glock 17 magazine to 50 rounds, or a Glock 19 magazine to 48 rounds.

The body is impact resistant polymer with witness windows on the sides, so a glance tells you how many rounds are left. The kit comes with a disassembly tool for the install and a loader, which you will want for a stack this tall. The change is reversible: pull the adapter and the magazine goes back to its standard setup.
