The Crosman C41 is basically a Replica of the Walther P38 although it does not have any of the licensing or trademarks of the original P38. The Crosman C41 is mostly metal and weighs close to 3 pounds, very heavy for an airgun adding to the realism. It is also one of the more powerful BB shooter available getting close to 500 fps. It does have a working slide that you can move back and forth.
