I purchased the Snake Slayer IV 357/.38, then added the driving holster and a 3″ 9mm barrel. Having the option to change caliber allows me to make better use of the ammo I have on hand. Thought I would mostly be shooting the 9mm, but the 4.25″ .38 is so solid I am getting excellent accuracy with it. This is a really fun gun to shoot and you’ll definitely get some looks at the range.
