what I'm saying is that an affordable 10mm will sell out quickly vs an equivalent mainstream caliber (9, 40, 45). Perhaps Im wrong, maybe a gun store owner can chime in but I bet an affordable 10mm doesn't last 2 weeks notwithstanding availability. Just look at how many people in this thread are lining up to buy an expensive niche one yet they can get the same sig in 45 for half.If you are saying that stores sell out 10mm guns before other caliber guns,it would be because they don't order near as many or can they get near as many 10mm handguns.
It's not very popular so not many manufacturers make them in big supplies,except Glock
And why would they when they won't sell as many as other calibers?
