Never suggested that H-Ks blow-up more than Glocks, but I strongly state that no one ( no one meaning web surfers and gun nuts like the folks here) has the data showing that one brand of pistol is more prone to kabooms than another. The only data that would be meaningful is number of kabooms per X number of pistols(choose your own X whether it be 1,000 or 100,000). The only people with this kind of data may be manufacturers and/or gov't agencies.
You may personally like one brand of pistol over another but that's your preference, it doesn't mean that your favorite is better.
I shoot, therefore I am.
