Thanx very much for the information. The serial number of mine is less than 500, so it's very early in production. Is there anything I should look out for? It hasn't been used much at all, judging from the wear points on the slide and frame, but I am unfamiliar with the weapon. By the way, mine has no rear sight. Some numb scull took it out,(I would bet a gang banger, you know, the "spray-and-pray" crowd). Are there any recommended tritium or at least adjustable rear sights to retrofit or do I have to buy a non-adjustable unit from Detonics? Thanx again. ~malhond
