Have any of you fellows had any experience with the trigger pull on the Hungarian PA-63 pistols? I have seen 3 in a row that have an extremely hard one both in single and double action. Somewhere I have read that the trigger spring in the PPk would be a cure. I know I would have go beyond field-stripping to fix my problem so my second need would be a source of detail-stripping. For any help you all might offer I would like to thank you in advance.
