So in the end, I was receiving a brand new Heckler & Koch USP for the one that blew up in my hands. To compensate for the FFL fees + the couple boxes of ammo I sent back for testing, ammo company sent me many boxes of .45ACP my way. Street value for the ammo provided to me I think doubled, or tripled of what I had spent in fees & ammo returned to them, so I was pleasantly surprised by that & thanked the gentleman from the manufacturer who had handled my case & helped me through the whole process.
Way the ammo manufacturer handled the whole process, I didn't see a single flaw in it. Not even once, anything they did or ask got me frustrated. They were total pro. I have gained much respect for this company & it is frustrating that I can't give them props in fear that by naming the company, it would actually reflect negatively on them.
Kind of funny, kind of ironic. Just few weeks before the accident, I had watched this youtube video of ZQI ammo(note: this is not the brand of ammo that blew up).
I've been buying bunch of these, as they are just under $10 a box at Walmart for the 7.62x51mm I shoot. It's a cool video & I recommend you check it out yourself. When I watched it, I thought to myself, "All that ammo..... How could they possible run a effective quality control? Impossible!". Just about a month later, my gun went kaboom.
All I can do is look on the bright side. All my fingers are intact, and no notable injuries. Received replacement handgun & compensated for all expenses, even got a additional mag for free when I got the new gun(USP mags are expensive!!). Ammo company, while they did not admit fault, they did step up to make it right & without a single hesitation.
As for Heckler & Koch, while they showed very little interest in what happened, at least they were communicating & after doing much research online, the rumor about how the USPs are designed to blow up in the way they keep the injuries minimum seems to be true. Most suffer injuries to their hands, but all the cases I saw, none of them lost fingers, or suffer major injury. Some burnt their hands, or got cut up little bit, but I think the main thing in such accident is that hands & fingers stay intact & they did.
Finally, I hope this post helps those who may go through similar unfortunate incidents. Please feel free to contact me for any advice, or questions you may have. Thank you for reading & happy shooting! :)
