I own three 3rd generation S&W pistols, all in .45ACP. All are reliable and accurate. My 4516-1 is an all-steel compact model that is easy to shoot well but a bit heavy. The 457 is the same size, but has an alloy frame and is one of the "value line" models. I've been very impressed with it. I also have a 4563TSW which is a full-size alloy framed pistol with accessory rail. I could do without the rail, but the gun is very high quality. I've replaced the factory grips on all three guns with Hogue rubber grips, and it is a big improvement in feel and handling. I think the guns compare favorably to just about anything on the market.
