I carried a J Frame of some sort since 1980 up until 2019 when I got the opportunity to shoot a friends Sig P365. When Sig ironed out all the issues with the then new gun, I bought one. After a few months of testing, shooting and familiarization with it, it became my EDC / CCW and has been on me daily for almost 5 years now.
I now have over 6,000 rounds through it without a hic-cup and it is with me daily. Not only have I not gone back to my J Frame, I don't think I've shot it since. I believe in constant practice with whatever gun & ammo you carry and I got to the point where I was not enjoying practice sessions with my carry ammo anymore. My carry load for the J's were Buffalo Bore 158 grain +P SWCHP and Speer 135 grain +P GDHP.
Shooting the Sig was so much easier, it is more accurate at any distance, allows for greater round capacity (more than double), has better ballistics, is easier and faster to reload, weighs 5 ounces less than the J's and is smaller, flatter and has way way better sights. To me, my 40 year EDC J Frame has now been retired and unless it is an emergency & I doubt I will ever again carry any revolver. To me they have been obsoleted for EDC.
All that said, one must carry what they shoot best, feel comfortable with and can feel confident with. If a J Frame still fills all those needs for the person carrying it, then I guess it is still viable for that person. All I can suggest is never stop practicing with it, do lots of reloading drills and shoot it well.
