Both of these rifles are similar to each other. Here is the difference. The Viper cost about $30 more and is designed for hunting. The Shadow is designed for small game hunting and plinking targets. The Viper has a lifetime warranty and the Shadow has a 1 year warranty. The Viper is a little more accurate than the Shadow. Both fire at 750FPS, have a 2 stage trigger and are spring piston driven. So for $30 more you get a little better rifle in the Viper.

Gamo made a Viper Express Shotgun not a Whisper Express shotgun. They do make a line of Whisper rifles but none of them are shotguns. In fact the Viper shotgun has been discontinued.
Currently Gamo makes an "Air Shotgun" that fires both shot or a .22 cal Pellet. It's the Viper Shadow Express.
It's good for SMALL Game hunting. Like birds or squirrels.
Get the Silent Stalker, it is far superior in quality. The IGT system is much better.
This is like asking is Ford better than Chevy. It all really personal opinion. The Gamo cost a little more but both are rated at 1000 FPS. The XT has a wood stock the Gamo has a synthetic stock. So the choice is yours.
It might fit, but why would you want to do that. It has no gun powder and won't fire.

Take a look at the comparison chart (see the link below) I think the Gamo has a slight edge over the Black hawk.
