This is an older Smith & Wesson auto. I’m not sure of the value as the blue book on it only showed the 745 IPSC model, which looks just like this, but has a fixed rear sight. It’s Single Action Only. The safety lever is only a firing pin blocker, and does nothing to prevent the trigger from dropping the hammer.
The grip is slim, giving it a feel much like a SIG P220 with factory synthetic grips. The checkering on the front strap is a little rough, but it’s factory checkering. Over all, I like the gun.
