Cuttin' Yer Loadin' Port
Howdy,
The Kirst will work without the loading port but You'll have to Knock out the wedge and pull off the barrel and cylinder to reload, just like the R&D.
Cuttin' yourself a loading port is easy but kinda time consuming.
I think I musta' went through a dozen Dremel sanding drums last time I did it.
One really nice side benefit is when you put the percussion cylinder back in with the loading port cut-out The cap fragments just fall out the right side as the cylinder rotates. Cuts WAY down on cap jams. The downside is the hot cap fragments fall onto your trigger finger ! (unless your a lefty, then no problemo!)
Just take yer time and work carefully grinding out the port groove. Test fit the converter with a shell casing and only grind away enough metal to allow easy loading and ejection. Most folks use a little allen wrench to poke out the brass. It pretty much falls right out with mild "Cowboy" loads.
Good Luck,
Cincinnati Slim
