I have a Black on black XDS 9mm I'd like to trade for the 4.0 model. I shot my friend's 4.0 and I really liked it more than the 3.3 in barrel. My pistol has about 200 rounds through it. 3 boxes of FMJs and about 50 Hornady Critical Duty rounds. It has all original goodies and paperwork. This was made post recall. I bought it in November I think. If you have a 4.0 let me know. I can add some $$$ if need be. Thank you.
