I’m not sure what the advantages to this design are, but it looks interesting.
UPDATE: Uncle says it’s to get a longer barrel in a smaller package. Didn’t think of that. One thing though, is I thought it was pretty difficult to do a straight blowback operation with a cartridge as powerful as 9mm? Hi-point does it with its 9mm pistol, but it also has a huge block of metal for a slide. Exceptionally powerful springs in this maybe? Is that going to be reliable enough? Someone who knows more about gun design that I do can hopefully answer.
