I have been reading up on 10mm Auto ammunition lately, and on one site, I can't remember exactly where, I happened upon a comment that the Witness pistols in 10mm were "notoriously undersprung". The writer suggested switching to a 22# Wolff spring for better performance. My pistol will begin to cycle slower (occasional failure to fully chamber the next round) as it begins to get dirty, somewhere in the 50 to 60 round count. It is, however, nicely accurate, and when clean, functions perfectly. Anybody know about this ? I'm wondering what the factory spring is.
