The mag is designed to be left loaded for storage with no degradation of function and we assessed that by leaving it loaded with a box of 115-grain Federal Syntech for two months. This is what happened when we took that load to the range.
We ran the drum several times with a mix of both range ammo-- 115-grain Federal Syntech polymer-coated TSJs-- and self-protection loads such as Federal Law Enforcement 124-grain HST jacketed hollow points, all without failure. In all, we put about 400 rounds through the D-50 GL9 pistol drum without issue.
