Locking Bolt
I am aware that Parker Bros. made a design change in 1911, I believe, that added a hardened locking insert. I believe I've also seen that they retrofitted guns returned for service to the new design at no charge.
Obviously, the company realized or thought they had a problem with the original design. Just wondering how much of a problem the original design really was. Since many of you are using guns that predate the change, how many are experiencing worn locking bolt bites? Have any of you retrofitted older guns to the new design? Is the locking bolt itself different? Etc. etc.
Just trying to learn something on this subject so your thoughts would be appreciated.
