Glocks chew through almost any ammo, reloads, etc. The lone wolf alpha barrels seem to have a tighter chamber, so if the ammo/chamber is dirty or out of spec I’ve seen more FTFs and stovepipes. This could also be additional mass of a barrel with a smaller bore diameter because mine are .40 —> 9mm conversions. The road down glock mods is fun, but I’ve not found it to increase reliability (I’ve gone so far as to build a glock without a single glock component, spring or pin.)
