The full-size .38 revolver is a fine weapon. Not an ideal choice for concealed carry, but certainly not impossible. The holster is key. The right holster makes a carry gun safe & secure, and ensures that it is accessible when it is needed.
There are plenty of holster styles available, from a variety of manufacturers. Leather, soft nylon, rigid polymer. Strong-side, weak-side, on-the-waistband, inside-the-waistband, paddle, pancake, shoulder, ankle, pocket. There is a holster for any carry need.
If you need a holster for a full-size .38 revolver, try your local gun store or any of the reputable online retailers.
But don’t decide to use your own ass.
I would agree, there has to be better ways than “ass carry”
I mean, that takes “deep concealment” to a whole new…low.
