Right now there is a 15 round mag cap on all guns ..But this is murky in terms of what is pre ban and not ... It sounds like 99 of the rual cops dont give a crap about this and wont do anything ..
As of right now there is no AWB that I know off .. I am unsure if Denver still has a legecy ban on AWB and over 10 mags ...
There is no more PPT withouth FFL
That all said NFA is still legal and other then making you take the carry course in person ( you use to do it online if you wanted to) I think they are still shall issues.
Up until last year they were one of the more gun freindly states but now ...
But OC is sitll legal no permit and the deal is with CO it is like IL in many ways a lot of urban CA types with libreal rep fighting the rual farmers and good old boys who want there guns .. Already 3 polications have been recalled ..
But as of right now both bills to kill the mag limit and the FFL only PPT have been killed ... So there is a long fight ahead
And for above 15 round mags for HD I dont know the sense I got is the cop wont care esp if you got them at some parts prior to the ban .. But if they wanted to be a pain about it they could jam you up with it
