CCW isn't an issue as Remington's about 6'2"- six three-ish and weighs in just about 210lbs give or take a donut; so fitting a bigger framed auto under his jacket isn't too hard;
Hey! I resemble that! At least I used to, before I lost some weight. In any case, the Grizzly Mark I is concealable for people that size. If your man handloads, he can load the Magtech 230 grain semi-wadcutter bullets over a hefty charge of WW296. This provides good penetration with a sharp edged bullet with a large meplat.
My Mark I is extremely reliable, accurate, and quite controllable for a magnum pistol. I could do better with it if my fingers were a little longer. Perhaps your character's fingers are of above average length?
Many of the parts are interchangeable with the regular M1911 type .45 pistols. Magazines are scarce and expensive. I have 3, so there is no reason your character could not have more.
Winchester loaded a 260 grain bullet cartridge at one time. No reason why your character couldn't find a few boxes laying around small gunshop shelves from time to time. It is the only expanding handgun bullet I would trust if I needed deep penetration also.
