I'm shooting a Glock 21. I just started shooting to this platform, so I'm new to it for now. Ftf Is failure to feed. I think the slide isn't making it back far enough before it returns to battery. I would say a weaker spring should fix it.
The DT loads are stamped 45 acp. No plus p or super stamp at all. Maybe they have access to a different powder, but who knows how they're getting that speed. I haven't cronographed them, so I don't even know if the specs are correct.
