Sorry, I shorthanded it. Yes, requiring the use of a TL is what is unconstitutional.
Hence, there is no longer any compelling need for S&W to include a mandatory internal trigger lock.
Then again, I will never buy an ILS equipped S&W revo. If those sale losses from me and the like minded are what they really want, they are welcome to continue ignoring potential customers.
Interestingly, I have a M&P9 that I really like. Why is it that I can get the options of trigger lock and mag disconnect "deleted" on that model, but S&W won't even do sprint runs or PC versions of revos without an ILS?
