Just got a new one and was psyching myself up for what I was led to believe was a nightmare...Fieldstripping...But oh joy just followed the book and was sucessful..Twice...I did find it a bit convoluted...I bought the pistol on the spot because I liked it but I know little about model variations...Mine is blued and has a 6.5 in barrel...Says Target on the side...Is there another model 512?..or something like that..?
