You're going to need to "handle" both to find the one that fits your hands the best. Both are well made "variations on a theme" … meaning they are both aiming at the same market. I have large hands (2XL shooting gloves) and the Sig fills my hand much better than the Walther. For a self defense / carry gun the nights are one of the best options you can get for the money. You will never regret adding night sights to your gun … black or even white dot sights disappear in the dark....give yourself every advantage to save your life or protect your loved ones.

sig also pays top pros to shoot their guns I suggest that you see if any local ranges have the guns so you can try them before you buy after handling and shooting them you will know which is best for you and I don't care for "night" sights

Hello Larry. Both are great and very reputable pistols. It's best to feel both and see what feels best in your hands and what you are most comfortable with. Night sights are totally worth it. Hope that helps!

Buy the SIG 320. It's a popular choice in competitive shooting. Walther had to bribe people to shoot their pistol and it's still not a popular choice.

Both are essentially equal feature, function and reliability wise Larry. Both get excellent reviews. The extra $54 would be money well spent with the much easier to pickup "Night Sights" plus the advantage of sight definition in low/no light scenario's.
