I can dig it.
To be a bit more clear; I was refering specifically to the grip–which is the hardest thing to conceal on a carry piece (IMHO, of course, that's just my thinking) and a compac on a j frame (or any other rubber grip that fully encloses the backstrap and bottom of the grip) will come awfully close to a standard round butt K with a stock grip and, say, a t-adaptor.
The question then arises as to whether one would do better with a K-frame snubbie (thus gaining a round) or just staying with the slightly more slender J.
The answer is definitely open to both debate and personal choice!
Right now, I'm *really* pining for this S&W model 12 I spotted at my local mom n pop store; it's a 2-inch airweight RB K, weighing in at 19 oz.
That's shy of what my 3" chief weighs; and I also have fat grips on that gun to make it easier to shoot.
I have enough Ks to know that I could still shoot the K frame 12 better than the rubber-stocked chief–even with just a t-grip... and the weight and ease of concealment would be very close between the two guns so equiped (again, in my opinion, of course).
At any rate, that's just one opinion. I still love the compacs for feel and recoil absorbtion on the smaller wheelguns, FWEIW. If I was going to be shooting .357 rounds out of a 5-shot J, that's the grip I'd buy.
