So, after missing the UPS guy on delivery attempt 1, I caught him yesterday and my 1860 is now here. Broke it down this morning and gave it a good cleaning. Not really finding much to complain about. The timing seems spot on and no really obvious burrs or machining marks. The cylinder gap is .06. The wedge was tapped in pretty solid but came out without any choice language and the nipples all came out really easily, they did have a little rust on the threads but after cleaning and a little anti-seize they should be fine. I do plan to replace them with Tresos, the Possibles Shop is currently out of stock however. I didn't find any of the screws overly tightened, wedge screw was probably stickiest of the bunch.
It might just be me but the action doesn't feel as stiff right out of the box than the previous Pietta 1851 I bought. Don't know if it's really smoother or if the larger grip just makes cocking it feel different. Even though I have smaller hands, the larger grip feels comfortable. Overall really pleased with it, I will post some pics later today or tomorrow when I have a chance.
