The Pro-Shot Premium Classic Box Kit (Pro-Shot part no. MPK3845) spans .38 through .45 caliber handguns, built around a 6.5-inch premium stainless micro-polished rod with a full-size swivel handle. Rather than a single generic jag, it includes three separately sized brass cleaning jags for .38 caliber, .40 caliber/10mm, and .45 caliber, along with a .38-.45 caliber nylon bore brush and a patch holder rated for .30 caliber and up. That range of caliber-matched jags means the kit actually fits each of the three calibers correctly instead of forcing one jag to compromise across all of them. It is a genuinely multi-caliber kit built with the right parts, not just a wide caliber range printed on the box.
