Colorado is inching, ever-so-slowly, in the wrong direction. "Minor", "insignificant" restrictions and anti-gun legislation has been passed almost every session for the past several years. Little by little, bit by bit.
What legislation do you speak of? There've been no new regulations since the "gun show loophole" law post-columbine. It's the only law we have that's stricter than federal.
The only gun-related laws since then are good ones:
-State-wide preemption, exc. denver's ban on OC and resident-only AWB
-May issue to shall-issue, 90 day max.
As for carry restrictions, they're not too awful. Government building, buildings with permanent metal detectors or security screening at all entrances, and K-12 schools are off limits. But Bars are OK so long as you don't exceed the same limit as for driving (0.05%), "no weapons" signs do not carry weight of law (even in denver), no restrictions on vehicular carry of handguns (long guns must have empty chamber per CDOW, but otherwise unrestricted). OC is good to go outside of denver.
NFA stuff is not regulated on the state level.
Basically, other than the "Gun show loophole" nonsense, we're only governed by federal law.
As for denver, yeah......It's like an island within the state. You have to separate it from the rest just as Chicago from IL, Los Angelas from CA, Detroit from MI, etc.
And yes, denver is not capitalized on purpose. I hate that city. It's a boil on the posterior of the state.
