I'm new to 10mm's and I thought the Sig P220 was their 10mm, but when I go to their website it shows the P220 as a .45.
It is a Lipseys exclusive.
Not any more. The 10 mm model of the 220 is available to all Sig dealers.
The Sig P220 has been around a long time in .45, I have the match elite, one of my favorite handguns. Couple months ago I bought the 10mm, its just as nice.

Look at the bottom for the three models with a -10 after P220.
I just got my sig 10MM. It is the SAO model with adjustable sights. I have not shot it yet because of the bad weather, but this gun is built like a tank! It fits my hand good and has a good trigger pull. Can't wait to shoot it.
