I never like buying things this way but with guns flying out the front door as fast as they come in the back door I just purchased online and wihtout much knowledge a SW 640. A stainless, hammerless, DOA 357 snubbie revolver for CC. what can you tell me about this gun? Hows the trigger pull? As one of SWs less expensive guns (less than 600) am I getting a good gun? I have just plinked around with a few berrettas and rugers and this is my first pistol to own for myself. Please excuse my ignorance here I usually study things of this importance before buying but with the gun market the way it is I did make a quick decision. Ive had 2 other guns I ordered sold out from under me, actually they were sold before I ordered them but the seller didnt take the ads offline after they were actually sold. Thanks much.
