I hate it when people post pics of knives, holsters, etc. and don't ID every item. Maybe it's to make us ask, so they know the thread is being read?
Your gun is better than a .22 for the role usually envisioned for the Kit Gun. I sold my M-34 mainly because it had SEVERE extraction problems. Then, I saw velocity results from one in an article by Don Zutz, whom I knew slightly and considered to be one of the more informed gun writers within his sphere of interests. That did not encourage me to rely on ANY .22 revolver for any but the smallest animals.
My idea of a kit gun is the .38 Special M-60-4. I also have a Ruger SP-101 for when .357 ammo is warranted.
You may wear the gun expecting to use it only if a snake becomes a problem, but larger animals may intrude on a hike or fishing trip, and humans are always a threat. I just don't think a .22 is the answer in this role.
That's a nice holster. It comes up further on the cylinder than does El Paso Saddlery's usual work. I prefer that. Lobo Leather? I had a very nice Safariland M-25 holster, lined and basket stamped, for my M-34. I sold it with the gun. I use an El Paso model VERY similar to the old Safariland M-29 for my M-60-4. Would have kept the Safariland for the Kit Gun, but knew that I'd be buying a three-inch barreled .38 to replace the .22.
The S&W M-36-1 is also a fine small trail and camp gun, but I really think stainless steel is indicated in that role.
Bill Jordan told me that he regarded stainless as the greatest advance in handgun design in about 100 years. I think he may have been right. Harry Archer's accounts of his revolvers in humid South America certainly argued strongly for stainless guns.
I think your .38 S&W loads are a lot better than a .22, but a .38 Special is preferable. Still, many here will want to know about that ammo. Those with British .38-200 revolvers will want to consider using them.
