Howdy,
I agree. I have a friend who purchased a Sig P226 in 357 Sig as a CPO weapon. When he opened the box he told me the only way he knew he had not received a NIB pistol was the CPO wrapper on his grips.
With the CPO weapons the factory goes through the entire pistol, replacing any worn parts and installs all new springs throughout. They then sell them to stocking Sig dealers, who can pass on a very nice savings to their customers.
I personally would not hesitate to purchase a CPO pistol, as I have my one friend who has done so, and seen posts from several other members of another forum I belong to. Those members also said they got a great deal on their CPO pistols. I have yet to hear anything by praise for the program the factory offers. Most of these CPO pistols are law enforcement trade ins. I can tell you from personal experience, most cops are really not heavy shooters. Regardless of what the badge says or its shape, a very small percentage of LEOs shoot reguarly. Most only fire their weapons when required to do so for qualification purposes.
On the range during quals, I often have a co-worker say I don't know why my score is lower than it was last quarter. I just shake my head and say because you have not fired any rounds since last quarter. Shooting is not exactly like riding a bicycle, you really do need to practice reguarly to become and maintain a high level of proficiency.
So I think that makes most of the CPO pistols an even better deal than they might sound to many. Most police weapons are not really high round counts as might be assumed.
Hope this helps a bit anyway.
