Always said I would never buy it, but I gave in just to have some around for target practice. (I have a buddy that is always trying to get "borrow" some at the range and I figure I would give them to him) Will it hurt my hk if I decide to use it?

No, I have shot thousands of Blazer Aluminum through my guns. One being an HK USP. It shoots fine. Just keep your gun clean and it will function. This has been my experience. A friend of mine would have issues with it out of the same lot as I used. He was not as anal on keeping a clean gun as I am.

It should work just fine in any pistol.

Thanks, I thought I had heard someone say it wasnt great for their gun but couldnt remember.

Blazer always worked ok for me in my Colt .45 and my S&W 645. I shot hundreds of rounds without a problem. I started using it because i gave up trying to invent a brass magnet to pick up the empties.

I probably have it confused with Wolf. My mind is slipping as i get older.

I've never had any issues with blazer ammo. 9mm, 38's and 45's. All functioned reliably and I use that ammo whenever I go to the range in Bayonne.
