While I am mostly on the 1911 train because I have ingredients to make food for it, I just installed the grayguns kit in both my p30 and p30sk two days ago. While I haven't shot either and it may be a few weeks before I get a chance to, they feel almost as good as my lazy wolf reduced reset package on my P30L from years ago. I think it is definitely worth the money and really negates the need for the extra expense of shipping and having the gun worked over. Just my $0.02.
