Actually for a pump shotgun and a presumably iron sighted M94 you could use a Gun Sock or a Gun Sleeve. Socks are in under $10 range , and most Gun Stores have a supply of sleeves that get thrown in with a purchase. The spiffier ones will have their promo printed on them.
Just remember that Socks are for trnsporting, not storage ( retained moisture issues ) .
A silicone treated sock, such as a Sackup or one sold by WM or Bass Pro is ideal for storage. They are only about $7. Just don't use the non treated ones. they are not the best to protect from banging around though. Sleeves are not good for storage unless you put the gun in a treated sock first.
