S&W catalog number 162523. Very very hard to find this 2.5" model. You usually have to buy the crimson gripped model to get the 2.5" barrel. I bought this, but it's just not for me. Never fired outside the factory. Comes as pictured with spent shell case and a bunch of junk paperwork. $425 or trade for... high end red dot high end low power compact AR optic. WA buyers~Peek at CPL and DL...no paperwork. OR buyers~Must use FFL that accepts shipping from private party. Buyer to pay actual shipping costs. Payment via Postal Money order or Paypal gift option.
