I have for sale a Compact size barrel for a Sig P250 in 357sig. It is a drop-in conversion for a Compact sized .40 S&W slide/pistol from the Sig factory. It has about 30 rounds through it, total. I got it for $200, but just a few rounds through it, and am moving out of the 250 platform. Looking for $150. This is quite a deal if you've been considering checking out this caliber! PM me if interested.
