I believe it!!!!!
I know for a fact that Glocks do go "bad". One of my shooting partners brought his model 21 (45 cal) to the Smyrna GA location the day before a Glock match for a tune up and a once over. We went to our range that afternoon to run through a for strings of fire for the following day and the gun exploded. The trigger disappeared, locked up the gun, shattered the mag, and bulged the lower frame. Well, long story short, Winchester white box-- Glock did not replace the gun due to "there were a number of extractor marks on the fired case". Well as we all know it is a possibility that one may chamber a round and not shoot it, and then put it back in the box for another time. Never heard of that at Glock I guess. Anyhow, after that bull, the arguing about the ammo, the bad attitude, and unprofessionalism shown by one of the armorers; I sold 6 out of 7 of my glocks, stopped shooting their matches, stopped pumping up gGlocks to everyone I met, and put the remaining 2nd gen model 17 up as a house warming gift for a potential bad guy.
Glocks do go bad with factory ammo. Why do they get all of the press? Because this is the information age, they blow to many pieces, and tend to hurt the user.
Do other guns "KABOOM", ah---- yes they do. I shot a pin match one night and a fella lost a Colt Delta Elite to a "Kaboom". I had a reload go in my Springfield 1911 (90s model). Case was weak and gave way at the 6 o'clock position. blew the floor plate out of the mag along with 2-3 rounds, cracked the left grip panel, and made a brown spot in my pants. No double charge, no malfuction in the gun, just a weakened 45 acp case with alot of mileage. Another friend of mine had a similar event with an officer's model. The barrel link broke as well as taking out the breakdown pin.
As you can gather from the description, not a ton of damage; a quick inspection, a part or two, and back into the fray. Guns fail-- that is a fact. Plastic guns will not fair well to the forces of a case seperation, out battery, or another malfuction-- a steel and wood gun will fair better under the same circumstances but there are no guarantees.
I my many years of shooting and hanging around ranges and matches has given me the oportunity to see the "what goes wrong" with guns and ammo. At times a mistake at the reloader can make a jewell into a pile of poo, putting the gun through unintended uses, and other weird things out there as well as the normal wear and tear tells me this will not be the end of the "GLOCK KABOOM" stories.
One more thing-- I wonder how all of these "plastic" guns (I know-- there are polymer) will stand the test of time. Metal and wood guns of the "antique" age have metal fatigue and break parks and fail. What will happen to those 65-70 year old plastic guns. Just thinking out loud.
