T/C Omega.

No blowback with my Omega allows me to only disassemble it's trigger & firing pins compnents every 3-4 range visits. The only mess on these parts comes from the 209 primer & that stuff is non-corrosive. So 3 out of 4 times, I just wipe down all easy to-get-at parts with a weak blackpowder solvent like T/C 13, Butch's Blackpowder Bore Shine... etc. When I do take apart the trigger/firing pin assemble, it's only a few minutes longer.
