My primary carry used to be a .38 SPCL J Frame - a 637 with a hammer that I bobbed myself. The gun conceals easily and comfortably, is simple to operate and extremely reliable. And the .38 SPCL has a proven track record.
But after reading many threads about carry capacity, and autoloaders v. revolvers, and comfortable holsters and belts, I came to the conclusion that if I am going to carry, there is no logical reason for me to choose the j-frame over a higher capacity autoloader that I can carry just as comfortably. Your choice may be different, and that is fine.
Now my primary carry is an XD Mod 2 .45 with 9+1. While it is heavier and slightly larger than the j-frame, it conceals very easily and comfortably IWB with a N82 holster and a sturdy gun belt. It has twice the capacity of the j-frame, and is a .45 to boot.
The only minor drawback with a N82 holster is that it does cover the grip and slows down my draw. I have a couple of other holsters on order to see if they are "something better," i.e., better access without much of a comfort sacrifice. However, when I carry OWB that issue is resolved.
I have some other semi's that I carry from time to time - a CZ75D PCR, a Shield 9mm, and an XDS 45 - but either the size (CZ) or the capacity (Shield 7 and XDS 5) did not offset the advantage of the j-frame's ease of carry.
But the XD Mod 2 has the edge (for me).
There is still plenty of carry time for the 637 j-frame - when I'm doing something more active, like riding a bike, or when I need to pocket carry.
Personally I think nothing comes close to the aesthetics and feel of a snub nose revolver, and I think the plastic guns are purely utilitarian and ugly. But I let those views affect my decision as to what I will carry. And after much consideration, and weighing the factors that are important to me, I came to the conclusion that a higher capacity, larger caliber compact pistol is what is best for me.
I don't think there's a "wrong decision" in what you carry, and I'm not going to second guess what someone else carries. It's their choice, they are adults, and they have weighed the pros and cons of their choice.
