The best app for gun sounds is "Armory" and the best app for choice of guns is "GunApp". For single weapon apps, you should use "Shotgun Free", "iShotgun", "iPistol", or search for a specific gun type, or place "i" in front of it.
For best gun reference you can use "TheWOPE" series (The Weapons of Planet Earth) ( http://www.thewope.com/handguns.html ), it has very very detailed info (with extreme search capabilities) about more than 1800 handguns in the handguns edition only.
