Not for nothin but my 2-6X Bushnell is still good on my 454. That's the only variable I've had on a hand gun. I've Had Burris, Nikon, & Leupold(still have it) 2X's. They all worked great. A 2X Pentax was just crappy! However that 500 is a different animal. I'd be P O'ed if my scope broke under recoil. Your more understanding than I am. Don't those advertisements & claims on their site say recoil proof or shock proof?
