Had the dude posted his 380 a week ago, I would have bought it. A few days ago, 30th, I bought a new 355 on line for $996.44 to my door.
I weighed in the factors that Ruger.270 posted above, "Ended up going with the Micro 355 as the size factor weighed heavily in favor of that model given that most of my hunting with be from smaller pop up blinds where space is a major factor. " Also, with a 10" power stroke the cocking effort should be a more manageable effort. The reason that I bypassed on the 400.
Although the speed of the 355 is a little lower, I think the biggest negating factor is the shorter bolts necessitating heavier broadheads. But in turn, that may be a bonus in kinetic energy for better penetration.
