Don't forget cost of ammo. .44 Special is more expensive than .357 mag and even more so than .38 special. .44 Mag is even more expensive. As scarce as ammo is getting, I have always been able to find .38 special or .357 mag. I saw some guys looking for .44 special and Bass Pro today and they didn't have any. There was .44 mag though.
The ATF should be a convenience store instead of a government agency!
