Edge of my lane.
At 3750 retail- if that pistol, when clean, greased and running Wilson ETMs, is not reliable with WWB and your duty load, they need to make it right at their expense and on an expedited basis, or give you a full refund. This is true regardless if this is your first Wilson or 21st Wilson. It is Unsat at present.
Blessings to you and yours in this time and keep us in the loop re how you resolve this issue.
