I'm waiting for mailing label from Glock warranty, but in the meantine was able to tap the slide off the bulged barrel. My untrained eye doesn't detect any damage except the bulge in the barrel. I checked the rails, edges of the mag that popped out, etc. Looks like it functioned as designed in the event of "catastrophic failure". If you've had a squib, how much besides the barrel was actually damaged? Wanna kill these ads? We can help!
