Just looking for parts for my sig

Double Action..action
Bought this from Palmetto State Armory 4 years or so ago. Could not pass up the price and wasn't sure I'd like the DA only automatic. I bought it because I couldn't pass up the price, it was soooooo cheap. What a nice surprise this gun has been, 6 lbs or so of DA pull and I can hit with it. This is the only DA gun that isn't hard to shoot, it pulls through easily while being able to keep the sights on target without moving.

The negative part of this gun is the DA trigger. While a great trigger it is slower to fire as I have to stage the trigger in order to fire accurately. This in and of itself might make more people reconsider purchase of this gun. It doesn't bother me at all and I love shooting this ultra-accurate firearm. I think police officers ought to be able to choose whatever gun their most comfortable with but in agencies with a specific firearm requirement for all, I think you could do much worse that choosing the P250. I do love the gun.
