I prefer a 45. My son his Tokarev in 7.62 x25
That round will scare the hell out of whatever it doesn't hit.
You can kill a man or any type of African big game with a .22. With that said, shot placement becomes more critical as caliber decreases. For myself, give me .45 the way Colt figured it for (semi) automatic pistols.
If your son is confident enough of his marksmanship even in the heat of a life or death encounter, more power to him.
How is the recoil on that Tokarev? My wife does not like .45 due to the recoil and when she shoots .38 Special out of her .357 snub, well that is about as much as she can handle.
Are you going to hijack this thread into one of those, "My gun is better than your gun" threads?
The simple fact is the 2nd Amendment says "The right to keep and bear arms shall not be abridged". The 10th Amendment says, "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
The 2nd Amendment is unambiguous. A citizen may own and bear/wear a gun. The 10th Amendment also prevents the usurpation of the 2nd Amendment by the states or the people because the 2nd Amendment does give the government the right to Prohibit the abridgment of the right to keep and bear arms. Clear as mud? So, all local and state laws restricting the owning and bearing of arms are unconstitutional. Why are they rarely challenged?
