Doh! I forgot the Glock 20 & its' compact little Bro' whatever they call that one.
Well I thought STI still cranked out 10's but if not my count is still stuck at five which only serves to reinforce what Gunfan stated. I thought there would be more, maybe I am just so used to reading about 10's that I have created an illusion.
The sad thing about 10mm is that it is referred to as a Reloaders Caliber and that in itself will make it less apt to be discovered by the masses, which makes it less appealing to retailers both of ammo and guns. It is hard for it to break into widespread popularity when it isn't readily available, not to mention considerably more expensive than altternative calibers when encountered in stock. Not that all those calibers are qualified to be considered alternatives... Whew, almost stepped in it right there.
