Google search it and see for yourself.
If you look in Shotgun News the used 40 cal Glocks are going cheap.
I recall that it is partly due to case thickness
and partly due to the amount of unsupported case in the Glock pistol.


I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
