Weapons Boberg XR-9 will come this year

 

This gun has a unique design where the magazine sits under the living, rather than behind it. This allows a longer barrel, resulting in more energy than a short-barreled gun with a cartridge the same size in the same chambering. I wrote a blog post and article on this weapon.
Can not wait to see the stress test of this gun. This is a very promising idea, especially if they can offer dual-stack model compact. However, after following the link a little deeper and find the video cutaway action, I am worried about the double duty round 'extractor groove must deal with in this design. First it will be used by the "hook bait" or whatever you call it, which seems to have forced the road there from the back of the case (and what holds the cartridge for this? Is bullets pounded against this weapon). Only after that can be used normally by the hook extraction, which appears to take on this same spot.
For that, it's got a lot of moving parts associated with eating whole round. I do not know if it gets bogged down vulnerable until we see it in action, but it puts a lot of work on the shoulder blow-back, so I would not be surprised if it's very picky about ammo this weapon.
