...As to boycotting ILS guns in hopes that S&W will drop the feature, it's your money and you can spend it as you like. That being said, the lock has been with us now for over a decade and S&W has shown no indication that they're considering getting rid of it, so you may be waiting for quite a long while...
I may be wrong, but I was under the impression that until recently, all S&W revolvers had the I.L. system, but now there are models that have no lock. If that be true, then there has been some movement in the right direction.
