Sorry it took longer than I expected. I did not hear from Stoeger Canada after they accepted my gun. I sent with the tracking number and signature required. I did not hear from them at all however I received a delivery notification on my door from UPS. I called UPS and asked them to hold for pickup.
There is a note for me in the gun case:
Gunsmith adjusted magazine catch. Gun was tested with 10 rounds of 3" KENT FAST STEEL BB and 25 rounds of KENT FAST STEEL 3 1/2"" BBB and no issues.
I will try to test by the end of this month and see how it goes.
