I have mixed feelings about the J-frames for CCW. I'm not a fan of the usual 2" models that many like to carry. The grip is just too small for me to shoot well. By the time I put a large enough set of grips on it to give me proper control and accuracy, I might as well be carrying a K-frame. Which BTW I can shoot much better.
For the record, my usual carry gun is a Colt Commander. So the whole idea of a carry gun needing to be small is a moot point to me.
I've also never been a fan of pocket carry. To me its uncomfortable, awkward and the slowest possable draw. I much prefer a good holster.
Yet I do admit to owning several of them. But then again, most aren't really the best for CCW due to caliber. I have a couple of .22s and several in .32 S&W Long. BTW: when the arthritis in my wife's hands got bad, she found her little 2" Model 30 to be just the thing.
Lemme see here, I own exactly three in .38 Special. One is a pre-36 Flat Latch which is mostly a safe queen. I have one older square butt Model 36 that spends most of its time in a drawer. Although I will admit to grabbing it occasionally for a quick trip to the store when I'm too lazy to put a real gun on.
And then there's the one J-frame .38 that I actually do like. In fact, its the only one that I actually consider to be one of my regular carry guns. The grips are big enough for me to handle well, the weight makes recoil in a .38 no problem and its plenty accurate out to reasonable ranges for its purpose. What I really like about it is that I can wear it in a good belt holster and pretty much ignore it. And it doesn't get in the way when doing strenuous physical activities.
This is my trail gun. We've walked/hiked many miles together and is probably the only .38 J-frame that I really do like.
