[Officer's Match]

The only thing about Glocks that could contribute to kabooms it that they will chamber rounds that other pistols may choke on (out of spec). A round that won't feed won't kb. So you could say their reliability could be a contributing factor. That, and gazillions of them in service.

Glocks also utilize polygonal "rifling" which creates a more efficient gas seal, therefore slightly higher pressures and velocities. And in some of their earlier versions the did have less case head support than some other designs. This is no longer the case, and hasn't been so for a good while. I believe that Glock builds some of the sturdiest barrels in a production defensive handgun.
