Abu American i suggest that if some one has not gone though a regular shooting pratice then dont even try to shoot a robber at close range even. The thing is that these automatic pistols recoils out of proportion for very new users and rifles of high caliber like G3 recoils back with force for new users, one can surely (90% chance) miss the robber, but the robber who may be trained then can point his weapon to the shooter may kill him.

I have heard lot of incidents like this in the newspaper.

I think you must be aware of its usage as you are keeping it.
