Very cool, guys. I think this is going to be a BIG seller for Smith. Maybe it will open their eyes and they'll change more/all of them back. I owned an IL 442 a few years ago and sold it because of the lock concerns (yes, I'm an admitted paranoid). I missed it ever since, so when these became available, I knew I had to snag one.
I also got one when it first came out a couple months ago, also got the no lock 642. Last week I got a set of Crimson Trace LG405s for each of them, AMAZING difference in shooting them now!
