I have the Sig p210-4. They had to have a business partnership to sell the border patrol pistols to Germany. Sig partnered with Saur & Sohns, a German rifle company. Saur made pistols for 2 years I think. This is one of them.
Neat thing is pushing down on the decocker decocks the pistol, and pushing down again recocks the pistol. It also has a safety. 32apc.
I found some Pachmayr grips for $18. The DW had a thin black serrated front sight which I prefer. Then a fiberoptic. I don't like the sight it has for plinking but he said it's original. Not a deal breaker.
