Buy it today. Demand is low, stock is high. Wait times will plummet in a month or two. I just picked up a Hybrid, because, why the hell not. My check isn't even cashed yet, but I have a feeling I will have it in my hands by July or August. I'm half tempted to pick up a .22 can and a Salvo because from an economic standpoint, now is the right time to buy.
If you think the shorter route is to wait for the HPA to become law, you may have skipped Civics class in high school.

Yes we are up to 136 cosponsors, and that's good news, but it's still got a long way to go.
