Hello, B:
I waited a couple days to see if others responded. Maybe silence is an answer.
Anyway, so you aren't hanging:
First, the 45 Colt cartridge has a relatively narrow case rim that can lead to cycling issues which can only be evaluated by test cycling a full seven (dummy) rounds from the magazine.
Next, verify that the firing pin strikes are well centered.
Be sure the trigger pull weight is satisfactory to you.
With you being in Canada, have a clear, written agreement about who pays for Warranty work and shipping costs, especially via a Canadian intermediary, to a U.S. location.
Very respectfully,
El Supremo/Kevin Tinny
