I have three of the old folded slide sigs. A P220 in 45acp, P228 in 9mm and P6 in 9mm.

For each of these I have extra firing pin, extra extractor, and several sets of outer and inner pins for holding in breech block in slide.

Aside from large parts like slide, frame, breech block are all the other parts and pins I may need to maintain these three firearms still available? I am thinking they are available as current production guns use similar parts, but not sure about that. I have sufficient magazines and mag springs are available from Wolff. Thanks.
