Waders; Good morning to you my cyber friend, it's been much to long since I've said hello to you sir, but I hope that all is as well as can be with you and your family.
Since as a Canuck we're not currently allowed to even have impure thoughts about carrying a sidearm for defense, my thoughts on the subject are akin to how many angels I think can dance on a horseshoe nail.
That said, for me personally and especially so as I've been aging, I'll take nice square sights rather than a trough or notch for sure. In the same vein, I can usually do better with a 4" barrel revolver than a shorter one, but that's my semi-old guy eyes and not yours.
If you can hide it and don't mind the length difference for concealment, I'd pack whatever I shot the best with - once again if we were allowed such basics of free citizenry here across the medicine line.
Stay well and all the best of our Lord's blessing to you all.
