Have you guys heard anything about the Gen 5 new Barrel having a shorter throat length so that 147 grain HST cannot feed properly? some are reporting feeding issues with regards to the 147 grain HST that the overall length of the cartridge is too long to feed properly with the new Barrel is this true? That depending on the lot of ammo, some 147 grain is good to go...others not so. The main advantage of Glocks that I admire so much is there reliability regardless of ammo. Is this no longer true with a Gen 5 Glock 19 Barrel? Some have suggested that the "plunk" test is necessary when using 147 grain ammo in order to ensure reliability.
