What has changed is the question that puzzles me. The trigger guard on my 1994 stainless PPK no longer clears the underside of the frame when trying to remove the slide. About a 1/16 of an inch of the trigger guard slide stop still projects up into the frame making it a matter of having to force the trigger guard down with a wedge. NOT easy and it never used to be be this difficult. So that's the problem and if any of you have a solution, please let me know. Thanks.
