I'm 6'3" 225#. I find I can conceal just about anything I want to, provided I dress appropriately. I used to carry a P229 exclusively, but my PPQ M2 has crept in. I carry the P229 in a MTAC and got an Alien Gear Cloak Tuck 3 for the PPQ. I can tell you the MTAC is head and shoulders better than the Alien Gear.
I got the Alien Gear combo and the OWB is...well pure garbage. Don't even think about buying one. The IWB I got is the neoprene backed (fasteners covered) with the sheet of support steel sewn in. It retains well enough, but the holster is bigger than it needs to be. The neoprene gets a little warm against the body. The screws for the clips constantly loosen so they're spinning around all the time. Noticed one of my retention screws the other day just disappeared. I always wear an undershirt and the neoprene backing makes putting the holster on a pain. The MTAC just slides right in and clips on the belt. To put the AG on, I have to undo my pants, clip the holster on the belt and do myself back up.
The short of it: don't bother with AG unless you are seriously penny-pinching to eat. And the PPQ is a fine pistol to carry. IMO, people way overthink carry size and end up with something a lot smaller than they could carry without any issue.
