I like to # my mags with a soldering iron, and the mold date always seemed like a convenient location. Is this against the law?
Pretty sure with the current wording on that if you bought it in another state, etc if you came into possession of this after the date and you weren't in the state of CO or even yet it was warranty replacement part, ...the list goes on and on, which is why so many Sheriffs said it was shit and unenforceable.
I can name several gun shops in Denver Metro who have dispensed with even disassembling the mags, and have factory sealed Magpuls on the rack under a sign "Parts Kits". Other shops are just selling the mags straight over the counter, especially to known customers.
I guess the way I'd phrase it is thus:
Possession of a large capacity mag (>15 rounds) is grounds for an inquiry - was the mag legally possessed before 1 July 2013? Regardless of where the burden of proof lies, it is a reasonable locus of suspicion, now, for investigation, because possession after that date constitutes a crime.
A prosecutor, as the law is currently written and interpreted, would have to end up proving that those mags were NOT in the defendant's lawful possession before 7/1/2013 to achieve a conviction, but any prosecutorial efforts expended in that endeavor would not be deemed frivolous or misguided before the fact.
Things seems to be turning in CO, where "you might beat the rap, but not the ride", and we Coloradoans have been very cavalier about that possibility before now.
