For the sake of the rest of us in the other 49 states, I hope they do not give in and that the law gets overturned in the court system.
I do not care one bit if my primers get marked and identified as being fired by me. They are either fired at paper, or I will have a darn good reason why they were fired at another human being. I say this due to the cost of implementing the technology.
In most articles I have seen on the matter (I have no idea if their estimate is accurate) it is said the cost to adopt the feature would add about $150 to the cost of each gun. While this is not a small number (about 25% increase on an average Glock), it is not insignificant. And what worries me even more is the slippery slope it can lead us down. Let's say one of the other restrictive states says that handguns need to have some other more expensive feature added to them, now the manufacturers are taking on even more costs. It is said that the increased cost will only be seen in guns for that state, but sooner or later they will need to spread that cost across all their guns if enough states enact ridiculous laws like this.
