The main reason I have my 642 is that the 442ND that I bought several years ago was claimed by my wife and I hated having to ask her permission to carry it! I like the centennial style J frames best. I've just bought a 649, first bodyguard style J frame, so I'm about to find out what I think about it.
Brick,
I seldom carry in my pocket, but from considerable long experience looking for a suitable way to do so, I will not willingly carry in any pocket without using a pocket style holster. For me, the simplest ones are the best. About a year ago, I attended a gun show where El Paso Saddlery company had a rep there with a large sample of their holster products for sale at discount. I bought a simple leather pocket slip, smooth leather in and rough side out, for both a Ruger LCP and a J frame S&W revolver. The holsters have a raised area on the spine of the holster (on the side where the sights fit) that tends to catch easily on pocket material and shuck the holster off the gun as you remove it. The holster is thin and comfortable, and it will work in your pants pocket if your pockets are not too tight on your leg and the gun disappears pretty well, not completely, but just shows as kind of a bulge, no real gun outline. This is in jeans, why I typically wear. The shape of the holster keeps it upright and in good position in your pocket. There are many models and brands made, but I get along with the EP holsters as well as any I've ever tried. They also work pretty well in a coat pocket, depending on the shape and size of the pocket.
As for belt carry, I have long been a huge fan of the Slim XC IWB holster made by Tim at TTGunleather.com. After getting my first one of these and finding it extremely well made, extremely comfortable, extremely functional, priced very competitively for a semi custom holster and the first IWB holster I have ever been able to wear and like, I have bought them for both revolvers and semi autos and carry nothing else concealed. The design, quality, and construction is excellent, and Tim is an excellent vendor to do business with. His wait times are normally between 6 and 8 weeks, and he is easy to communicate with. Take a look. If you are interested in an excellent OWB holster, I own and use his Model DD00 holster. I use them mostly for range work or outdoor open carry, but a long tailed shirt or jacket also conceals them very well, especially for short barreled handguns. Some guys hate to spend over a hundred bucks for a holster, but over the years, I've found that if you buy right the first time, you don't have to buy again, and you don't normally get good quality stuff that works for cheap! We all have different needs and body shapes, as well as expectations, but I cannot recommend TTGunleather's products more highly. Hope this information helps you (and others). I'll be happy to answer any questions you may have.
