I love mine ! I gave one to my son when he turned 21 (his pick) The one I have now shoots better than most 1911 types. The adjustable sighted 645 stays in the safe , every now and then I take it to the range and am in awe. They have a beveled mag well,ambi-safety,8 rd. mags. Wood grips can be found for them (mine never installed) Even though its stainless,treat it like a blue gun...it will rust and scratch easily. I tore down my 659 and glass beaded/sand blasted it and it turned out great! They quit making that model around 1988,to clear the way for the 4506. I like the 645 better. (Had both)
