The rpd. I know where the gun is, I know what the hold up is, and the retailer has kept me informed. I ask them questions and they answer. Hell if I wanted to make the trip I could shoot it. The only hold up is the lab. Once that clears I'm sure the retailer will update me on every step of the transit and shipping if I ask.
I wasn't in on the RPD but I would buy one in a heartbeat now.
