Which handgun for Alaska trip?

[Hesa Hard1]

Just to clarify, I don't want to buy a new gun, so the choices I listed are what I have to choose from. I do have a 12g shotgun, but don't want to have to haul it around.
I will probably take the G29. Seems to be the best compromise of concealability, portability, and power.

Solid choice.

The 4.6” G20 would offer a slight boost in ballistics, but with UW/DT/BB-level ammo, the velocity lost out of the G29’s 3.8” tube is less than you might think, especially with the heavier bullets.

Check their websites, but some of these vendors offer comparative fps/fpe stats for their ammo as tested out of different guns, and happily they’re real-world guns too, ones that guys actually carry - i.e., 5” Delta Elite versus 4.6” G20 versus 3.8” G29.
