That is why that I moved to the Metroplex from the Texas Panhandle. They had over a foot of snow up there last week. The elevation is around 4,000 feet. It can snow up there from Labor Day through Memorial Day.
If your Slim Jims are period correct, they should have belt loops that will accommodate only a 2" waist belt. The belt pictured in Lucky R. K.'s photo is correct. It is important to remember that civilian Slim Jims are pre-California Gold Rush. They were designed to be worn on military style belts of that period. This feature carried on throughout the 1850 and early 1870 period. In our collection, we have cartridge belts that were made in the early 1870's for percussion conversions that are only 2" wide to go with Slim Jims made for cartridge conversion revolvers.
