I am planning on buying a new pistol for cc. My plan a 357 but I don't want a snubby.due to loss of power and sight radius... How hard is it to conceal a 4" revolver? any suggestions on the best way? I prefer small of back iwb
1) Snubbies
Snubbies don't lose as much power as you think. Bullets will work within a range of velocities. Make sure the velocity is within that range out to 25 yards and all will be well. See Stephen A. Camp's website and various threads around here.
Now, you can look at a 2.5" or 3" barrel. The trade-off is the revolver is more difficult to shoot due to the shorter sight radius. A four inch barrel is manageable. I notice a very large improvement in my shooting with a 5" barrel over a 3" barrel. The four inch barrel is a reasonable compromise. Carrying a gun with a 6" barrel would be very difficult.
2) Concealment
The first trick is to figure out if the barrel is too long. If you carry IWB, a gun that is too long will print in the rear pocket area. A pancake holster means you'll need a longer covering garment. Sometimes, a long barrel or slide will cause the gun to dig into my side when I sit in a squishy chair.
Second, you'll likely want to carry in various positions. Generally, I carry in the pocket, appendix position IWB, strong side (either IWB or OWB), and off body in a Dillon "Plan B". I need a very short barreled revolver for comfortable carry in the appendix position. The S&W Model 442 or 642 works great for both the appendix position and the pocket. I carry a backup revolver anyway, so the J-Frame just moves around as necessary. You may be able to carry your revolver with 4" barrel in the appendix position comfortably if you are tall and thin.
You can increase your holster's ability to conceal by making sure the straps are split and not on the face. This makes for a thinner profile. Not all carry locations can benefit from this. There are a few holsters with offset loops for the appendix position.
Forward cant for strong side carry is very important and helps reducing printing by the stocks. Revolvers are "tall" overall (as measured from the top of the rear sight to the bottom of the grip). You will find many holster makers do not offer enough forward cant. Google for "compiled list of holster makers" (or similar) for a large list of sites to visit. Look at El Paso Saddlery's "Dual Duty" pancake holster for an example of lots of forward cant (unfortunately, they do not make this for revolvers).
Boot style grips are very important. Many makers offer such grips, including: Badger Grips, Herrett's Stocks, and others. Ahrend's do extend downward past the bottom of the frame, but you can order them unfinished and modify them.
3) Weight
Buy a Comp-Tac kydex reinforced belt. A holster with split loops will distribute the weight and make it feel slightly lighter. Weight in a revolver is an advantage when shooting and I think it's more important than convenience.
