I don't know the nitty-gritty detail levels. Just that I'd comfortably pay - in taxes if necessary - to directly support the second amendment in ways that aren't "Just play more defense." I've written this up before, so not precisely worded to your point, but it's what I've got.

1. The Second Amendment support has very noticeable holes in its support level. The centers of those holes - we know every single one of them by name. And. They're mostly currently on effing fire. If not today, this second, recently anyway. Note well how crucial this is: Three perennial Red States and their Metropolises. Texas, Utah, Georgia. That's Houston, Salt Lake City, Atlanta. "Years since last R Mayor", when you add all three up, that's Two Hundred Pus Years This is not accident. The Democrats have been operating on "Seize the cities" mode for awhile. And the Republicans have been "Well, why do we care."

2. Things that are not fundamentally locked into a specific viewpoint tend to drift Left mighty fast as the old leadership retires and the new hires start hiring their own eventual replacements. This means things like the transparency requirements, metrics to measure success, reporting requirements - bake as many details as can be right in there.

3. The cities appear to me have had a long-running active plan to kick all the supporting pieces of a 'gun culture' out. On all fronts - every little hassle that seems odd, ineffective, or flat stupid. The point was increasing the hassle. Ranges, dealers, pawn shops, gun shows, smiths - the works. "Go do it in the suburbs".

4. The consequences of Point Three is: it pretty much requires intervention from a higher level of government to reverse. Am I ecstatic about requiring this? No. It's fundamentally 'not conservative' if you're judging from that angle. But. The right to self-defense (bearing arms) isn't merely something 'allowed by government', it's supposed to be protected by government. And the cities have abrogated that completely. "The police do that." (Stop giggling).

5. Police Training. This will seem like a side note, but I'll come back to it. There's currently a lot of emotion and all sorts of calls for "Improved Training" sort of dictates. Lifeguard/EMT/CPR training goes through an "independent third party" in many places, the Red Cross. Allowing nature to take its course will probably end up with something moronic: Letting ANTIFA/BLM set up the training is no good for anyone. But drag the 'training, testing, certification' out of the police buildings. And let others see or take the courses. (No, not particularly concerned about 'leaking' individual skills, the communications and discipline are the actual force multiplier.) But I wouldn't be leaking counter-terrorism specifics either.

6. What about if "Some higher level" of the Federated system imposed requirements for one building in each "Metropolis". "Thou shalt allow a range/shop/ammo/pawn/turnin/testing/course/training/paintball/virtual facility". I'll talk Federal, because we don't actually seem too, too far away, and the Democrats currently are on fire. But it could be county/state some places.

7. Here's the kicker. Offer large monthly payouts for firearm competitions for a mild entry fee. A fee large enough to attract interest from groups that habitually avoid anywhere near "trained gun-owners". For some inexplicable reason. Alternate banning Feds and "Former winners" and ... do everything possible to do all the New Age silliness "Group Building" and "Team Events" and ... all the same stuff aimed at little things like ... making cops human again because they had lunch in the cafe with them.

8. Million dollar prizes. They're how much cheaper than Trillion dollar 'let's rebuild the city' plans.
