When I replaced the extractor on my P3AT many many rounds ago, I used blue Loctite to secure the extractor screw. I did this based on actual experience of the extractor working loose. Also, the P3AT had a reputation at the time for the screw working loose and the Loctite was a common suggestion. I've never bothered with my wife's P32 extractor screw at all and it has never come loose. Should I Loctite her extractor for good measure? ...or is it best to leave well enough alone? Don't know why this question never crossed my mind until now.
