I think I'll rule out the PF9. I do like the 3913 as I have a 5906 and it's very similar. I have to say I really like that Boberg XR9, that gun is nuts! Rear-feed huh? Does it handle HP ammo ok? The Boberg is definitely more than I want to spend, but it's not out of feasibility and I have to say I'm a sucker for unique design. How's the trigger on the Boberg?
