Thanks for all the feedback so far. I hope to read even more from others.
FWIW, I do handload, and I am well aware of the potential .45 Colt has when handloaded. Also, there are factory loads like the Buffalo Bore "Heavy" .45 Colt loads that seem to outperform even heavy .44 Mag loads.
I'm familiar with the sights on both, and have already decided to go with either Ashley Outdoors ghost-ring sights, or add a tang peep sight. I simply don't like open notch sights on a rifle, whether it is on an M1903, an SKS/AK, or a lever gun.
The point about the idiot buttons (safeties) is well taken. USRAC should be haunted by the ghost of John M. Browning for adding that button in the dent on the side of the receiver.
However, for this acquisition, appearance is not really an issue. I need functionality above all.
