Hi,My name is Robin and I'm from Belgium.I have a few questions about my recently bought (about a year ago) Delta Elite.1) I can not find my serial number back on the colt site!?! Mine is DE248xx.2) is this a first gen?3) is it safe to shoot hot loads in it. I got 500 Norma's with them in plastic boxes and 1 org box of 20 cartridges (200 gr) and according the owner it's still the original ammo from the early 80's. He bought the gun as a defensive gun what was possible in that time. He shot about 100 bullets through it.Gun was checked by a gunsmith on wear and found ok.I want to shoot it every now and then.Any info is welcome.
