I carried a J Frame as my EDC since 1980 - that is up until a few weeks ago when I purchased a 9mm Sig P365. My M60-7 has been a reliable, accurate and comfortable Revolver to carry and I have always trusted my life to it. I carried the best defensive loads I know of which to me is the Buffalo Bore (#20A) 158 grain +P LSWCHP-GC moving out of the 2" barrel at 1025 fps - serious medicine! Coming in at second place is the Speer Gold Dot short Barrel 135 grain +P which has less recoil but also has 165 fps less velocity and 23 grains less bullet weight, so the bullet's energy is a lot less than the BB'S, (BB energy is about 370 ft lbs vs the Gold Dot at about 230 ft lbs).
! will be 65 in a few weeks and I find it more & more hurtful to practice with the J Frame with the BB loads. Even by downgrading to the Speer GD's, recoil gets harder to tolerate as I get older. That means I tend to practice less with it - not a good thing! I still shoot a J Frame quite well, but after experiencing one of my friends Sig P365's at the Range about a month and a half ago, I instantly fell in love the the Micro 9! It weighs less than my M60-7, is slightly smaller, however it holds 11 rounds (10+1) has what I believe to be about half the felt recoil of the J Frame, and has better sights and the latest generation has finally had all the problems the first generation had - solved! I also LOVE shooting it and it's a cinch to clean.
For me this is HUGE since I am NOT a plastic gun guy - and this Sig is the only one I own. I just find it so easy and effortless to shoot (even with Speer Gold Dot Short Barrel +P 124 grain bullets) I can practice with it all day long with no fatigue or pain. Now of course I could have put rubber grips on the M60-7 but that would make it all but impossible to pocket carry - defeating the whole purpose of the small gun. I never cared much for rubber grips.
The M/E of the 124 grain GD's from the Sig P365 is 345 fps. That's pretty darn excellent! So being that I've now fired over 700 rounds from the new Sig with ZERO malfunctions of any kind, I've put my M60-7 back in it's wrapping paper and original box - at least for now. The Sig just had too many pluses for me to ignore any longer and so now it is my new EDC. Unless I start to have a problem with the Sig, I doubt I'd make the J Frame a routine EDC again. That said, for 38 years the Chief's Special served me well and never had any malfunctions. In my heart I know that a Revolver will always be inherently more reliable - although the new 9's have gained HUGE strides! Life is always a trade-off!
