Thanks for the very thorough and concise response.
I’m a firm believer in having spare parts for important things. The parts I’ve come across appear to be in “like new” condition, sans packaging. But I can’t claim them as new.
As a recreational shooter, I’ll probably never wear these pistols out. But, 2020 does change one’s longer term perspective on what will or not be available when needed.
So I’ll just grab a service pack or two and try not to break or lose anything
