Here's a good discussion of the 940 from "The Firing Line" website. Read the whole thread because it starts as a request for help with a problem but ends on a very positive note. http://thefiringline.com/forums/showthread.php?t=225200
I spent a long time looking for a 940, knowing I couldn't afford it when I found it. Finally, I gave up on it when I found a Ruger SP 101 in 9mm.
The 940 has a good reputation. I like it a little better than the SP 101 because it is a little smaller. Rugers are heavy carry pieces. I think you'll be pleased with you acquisition.
