Mas, I recently picked up several boxes of DoubleTap .40S&W loaded with 200gr XTP-HPs which are rated at 990fps/1050fps/1100fps out of 3.5"/4.0"/4.5" barrels, respectively. Got these cheap as part of a package deal on a Glock 22 upper. These are definitely some stout loads but run fine in all of my Glocks. I know your reluctance to opine on rounds which don't have a street record but I welcome your thought on the wisdom of carrying such a load in winter for its penetration potential through heavy clothing. PS: LFI-I and LFI-II grad with great appreciation for what you've taught me and many others through the years.
