If you have a couple of MKIIIs have you thouht of converting one of them to a threaded upper... I have three of the MKIII Hunters and used the 5.5" as a base for a Tactical Solutions Pac-Lite upper.
Love how the balance sits the gun back in your hand....not too heavy and not too light....
Suppressor is a TS AXIOM Titanium....
Also just bought a Ruger 22/45 LITE, all black and it also matches with the suppressor very nicely. Is very light however and does need a trigger job...
