Found this from a Nevada seller on a CA-Based forum....
It's not mine, but I guess this would be proof that it's legal for production, based on the other "for sale" Stock 3 thread this one has proof that it's a legit stock 3 Small frame!
Kneelingatlas, the SP-01 trigger is better than the stock 2 after gunsmithing.
It's the ergonomics that don't work for some of us. Big meaty hands and stubby fingers like the Tanfo more than the cz. My short fingers had a hard time reaching the cz trigger.
And the mag button on the tanfo is better as well.
Single action trigger can be made to a bit better on the tanfo.
