Could use a little help with this one. Bought a complete blem dagger lower during the memorial day sale, and mated it with a complete Patmos Arms upper from JSD. Haven't tested fired it yet, just lubed it and have been racking the slide to " break it in". Here's the issue: If I rack the slide and pull the trigger, and keep the trigger held to the rear, the slide will not rack again. As soon as I release the trigger, the slide will rack. I swapped the upper with a couple different PSA brand uppers that are on my other P80 builds, and it functions normally. And, I've also put the Patmos upper on my P80 lowers, and they function normally. It's just when this particular Patmos upper is on the dagger lower I have the issue. The only difference with the lower that I can tell is the "birds head" vertical extension has the dimple in it like on newer glocks. Any thoughts?
