Well, the message they send to gun enthusiasts is great, but NYS probably didn't even notice. Unless, of course, they had a pending order for a million at a great price. (How you think the number doesn't matter is beyond me.)
I applaud them, and can only hope every other manufacturer (AND DEALER) gets on board.
The people who had their order canceled noticed. Guaranteed. And I'm sure they talk to their peers at least a little bit. Word will spread.
Remember, this covers ALL of New York. So if the police force in Cooperstown had an order in, it got canceled. Not saying it'll make a huge difference, but it certainly will get noticed.
