it is a tough decision, but possibly these two. The second picture is the runner-ups.
The revolver is a S&W Model 25 Mountain Gun in .45 Colt. The pistol is a Sig Sauer P220 in .45ACP.
The runner-up revolver is a S&W 686 in 357 Magnum. The runner-up is a Sig P22O ST also in .45ACP.
Did I make the right choice?
