I understand that with the -6 models came an engineering change that altered the frame slightly between the newer and older models. Would one of you who know provide photos or other technical guidance that will either confirm or deny this please?
I am not talking about the inclusion of the internal lock. Rather the space of frame behind the cylinder is longer on the newer pistols presumably to accommodate the floating firing pin?
I saw a photo while researching and cannot find it again.
Thanks in advance!
