I was wondering if these were still available?

This is actually one of those things I've been wondering if it would be even "legal" to do so, so I have the pistol...but wondering whether I should/shouldn't and would love to hear some people chime in as to what's been done in the past in situations such as this one.

I ordered May 6th, and never got any shipment details haha..

Hopefully I'll get them soon!
