I have more than half a dozen J's, a couple of them being 642-1's.
While I find my steel J's to be more easily treated as belt-holster/carry weapons, I've generally used pocket-holster carry for my Airweights (642's, 37-2 & pair of M&P 340's), meaning either front jeans/slacks pocket or inside jacket pocket. When I
do sometimes use a belt holster for one of my Airweights, I can easily forget it's situated on my waist.
As a LE firearms instructor, I've been fortunate to able to
practice using the same carry methods on a live-fire range, which I use for normal carry conditions. Periodic practice using a double & triple checked cleared, EMPTY snub, done in the privacy of your home (still minding muzzle control, of course) is considered useful by most trainers, but also being able to do it on a live-fire range, even if restricted to doing it under the watchful eye of an instructor, or a RSO during competition, or during quals for LE shooters, can be handy.
Drawing from belt holster carry (I have an older Blade-tech and leather holsters) is as "easy and quick" as when using that method for any of my other handguns. Drawing from pocket carry is variable, depending on whether you've already reached into the pocket and grasped the snub, or are seated, the tightness of pocket, the type of pocket holster selected, etc. I look at pocket carry as being a way to conveniently carry, but it's not necessarily something found over in the "fast draw" column.
Since awareness and staying ahead of someone else in their OODA Loop is alays preferable, I don't see the inherent issues that may typically have to be addressed in "pocket carry" to be a terrible compromise. Sure, using a OWB belt scabbard or paddle, mounted in a typical location as when larger revolvers and pistols are being used, can offset the difficulty of accessing a gun being pocket holster carried.
Once upon a time, some years ago, I briefly experimented with a "belt clip" device for one of my Airweights. Many years earlier (early 80's) I'd done the same with a similar style belt clip device for my Combat Commander. I stopped using it with my Airweight for much the same reasons I eventually decided the clip draw was unappealing for use with my Commander, meaning it didn't keep the gun sufficiently stationary and firmly positioned. It would tip, cant or shift, depending on body movement during normal and sudden shifts of body position and posture. I didn't like how the trigger wasn't covered, either (even though it was a DAO Centennial style snub).
I've long lost interest in using IWB holsters, for pistols or revolvers, but that's just me ...and too many years of having worn heavy work gun belts having left some easily aggravated 'hot spots' on my hips (glutes & iliac crests).
I don't use the type of IWB carry method nowadays often termed Appendix or AIWB carry, and I have my own reasons for not using it (both personally and as a LE firearms instructor). I know some other LE instructors who use it, but it's not my concern. Different strokes.
I don't use ankle carry, but it's handy for those who may be seated in vehicles, where they can surreptitiously draw their ankles close to their (reaching) hand without much contortion. Having to otherwise bend and/or kneel to gain access is rather situationally dependent, and during any physical struggles it not only puts your dedicated defensive handgun as far from your hand as is physically possible, but it can easily put it within reach of an attacker (especially if you've been forced to the ground, or have had your leg grasped).
I no longer use shoulder holsters, but they remain a convenient way to conceal/carry even snubs, for some folks.
Also, I hope Mas won't mind me posting a link to an older blog article of his, but some folks interested in using the venerable .38 snub for a dedicated CCW, off-duty or retirement weapon might find this booklet interesting. Like Mas, I may not agree with everything written by the author/trainer, but it's a worthwhile investment of time to read and consider for anyone who decides to carry a snub revolver. Like some already experienced motorcycle riders often comment when taking a MSF course, there's always something to learn they may not have previously discovered or learned on their own.

Just my some thoughts.
