This morning at the Trap Range a very nice old gentleman gave me an Iver Johnson (Uberti) "Cattleman" in .44 Mag. Searching around on the web they've their share of problems, most notably is the "soft guts" comment that pops up on most everything that I've found. Would it make sense, as this is a low use firearm, to disassemble, clean up & polish the "guts" and run them through some Caseinite to case harden them?
