Perhaps it may work in an emergency gun take away situation. There are not to many of those.

But if the bad guys get the gun home, how long would it take for them to crack the digital signature by running all of the combinations and then build their own transmitter capable of firing the gun.

Probably not more than 2 hours.

Consider the prospect of limited-try and lockout circuitry.

But if a child or criminal would get hold of the gun, it would be useless.

Probably not more than 2 hours.

Or go lo-tech
1. remove hand
2. extract chip
3. dab of super glue
4. affix chip to gun

child's play.

How long will it take to remove the grips and pull all the electronics nonsense out?

Probably not 15 minutes.

How long will it take to find a Patrolman's Union that will let it's members be used as guinea pigs for this unproven tech?

Probably geologic ages.

Not even the liberal democrat politicians who run most unions are gonna risk the blowback to them from an officer having a malfunction.

As long as the guns use a conventional cartridge, it still takes a mechanical linkage to set the primer off. The chip controlled thingy is (or will be) probably just some type of electric trigger lock or engagement piece. Just take the locking device out or permanently engage the linkage and you have a regular gun. No need to have the brainpower to crack a code and make a transmitter.

You're way overthinking this. They'll chop off the cops hand and dig the chip out later.

Why go to all that trouble when you just by-pass the reader system built into the firearm in the first place. If need be using knowledge gained from machine tool technology classes to fabricate any small parts that would be needed to mechanically override the electronic safety.
