Concerning the TC Patriot pistol, I'm looking at a picture of one in the 1987 Dixie Catalog. It is a double trigger sidelock percussion pistol which uses a single barrel wedge to hold the stock to the barrel.
Except for the sights which look a bit TC'ish it appears to be a traditional pistol. (By the way, if any of you buys one of these, the triggers are Bass Ackwards from normal set triggers. The forward one cocks the trigger and the rear trigger is the "real" trigger that fires the gun.)
Now, to enter the fuzzy area, the Colt, Rogers & Spencer and Remington revolvers (and similar brands) could easily be called "in-lines" yet, they are acceptable for conversation here.
The TC Scout causes me to bite my tongue, roll my eyes and grudgingly say to myself,"It's kinda like a single shot Colt revolver so I'll let them talk. After all, during the period up to the Civil war there were a lot of weird looking pistols that used percussion caps for ignition and while anyone showing up at a rondi with one of these would be run out of camp, unless any of the members complains I'll let it be."
Now, the TC "Encore 209X50" is IMO outside the limits for the Forum regardless of its appearence if for no other reason than it uses 209 Shotgun primers.
That's how I've been handling the issue anyway.
