I couldn't watch the whole video because of the heavy BS in it... That guy, and I don't care who he is, hasn't got the slightest idea what he is talking about. He takes a poor fitted 1851 replica and then explains why Colt's original design got flaws in it... Comparing Colt Walker's bolt, which is a 1846 design, and DID NOT work the way he describes it - i.e. bearing the recoil from firing and comparing it to the later and evolved 1851 Navy and 1863 NMA is just wrong. All the open top Colts have a recoil shield and it serves exactly that purpose - to limit the cylinder rearward travel during recoil. The cylinder does not slap the hand, it does not disengage the bolt from the cylinder notches, earlier design oval bolts did not bear any recoil. More importantly, the B/C gap on original Colts was never that excessive as his example, so his remarks about excessive endshake on Colts is just adding more BS to the mix... It's like taking the poor fitted Uberti arbors as an example that open top Colts are a weak design. No, it's not - done properly those revolvers are pretty strong and the design is more than adequate to withstand years of use (with a Cap & Ball cylinder, mind you, not a cartridge conversion one which has completely different recoil forces). That guy should really start to read more and talk less, a lot less.
P.S. And yes, this post belongs to the BP section of the forum. Where we can enjoy watching fellow members tearing his rears apart... OP, you really missed the big fun posting it here.
