I read something (see exerpt below) and the Lyman manual also has a similar statement on the 40 ca page, somewhere that shooting reloads from a gun with a barrel that is not fully supported "like Glock" is not recommended. Any thoughts on this, I have both 9mm and 40ca? I know people reload ammo for Glocks right?? Of course I didn't read this until after I bought a square deal to reload 40ca for my 27 and my 23. Thanks in advance. Melissa "WARNING: This data is intended for use in firearms with barrels which fully support the cartridge in the chamber.
