Bar-Sto Barrels for Glocks?
Being fairly new to the forum, this topic may have come up before and, if so, I hope I'm not boring people. There is a fair amount of information on the internet concerning Glock barrels not supporting the case as much as other after market barrels sold for Glocks. This means the base of the case has slightly more exposure when the gun is in battery with a glock barrel than with after market products such as Bar-Sto. The increased exposure may make the incidence of kBs more likely. It appears this almost never occurs with 9 mm guns - two reasonably confirmed reports- but is more common in the 40 caliber models and possibly the 45s as well. What do forum readers know about this and is there any good reason to purchase an after market barrel to reduce the liklihood of a kB in the 40 caliber line?
