#6 is currently for sale at CSMC, IIRC.

I've seen #10 on social media, somewhere.

I've owned two first year guns, both mid-four figures, both with Twin-Single Triggers and and the stepped Non-Crossfire vented rib. As Ted says, the Twin-Single triggers are very cool, and were a step towards figuring out the single Selective trigger that's all but standard on modern two-barrel guns.

I can't recall what the "P" in the serial number means...I'll try to find out.

Is this gun for sale somewhere?
