Wow, there's a lot of bulls&$# flying around here. Here we go:
Here in the US you're allowed guns for "personal protection" or "hunting".
You don't need a reason. You can buy a gun just because you want one, state laws permitting. I own four.
In USA i have hear that you can obtain permission even for M-4 or M-16.Is it true?
In something like 38 states, you can own a real machinegun such as an M-16. You have to fill out a lot of paperwork and do a lot of crap, though. Google "NFA Laws" if you want to read about it.
Many rifles that are semi-automatic versions of select fire or full-auto weapons are still allowed. This includes guns like the AR-15. I own one and have included a picture of myself shooting it (with my face censored out).
For guns, I think there are certain states where a .50 caliber round is legal but in most states the highest you're legally allowed to go is a .45.
Incorrect. The federal limit is .50 inches, although this is excepted in the .600 Nitro Express and sporting shotguns. Larger are usually considered destructive devices under the NFA. Next, only one state has outlawed .50 caliber weapons, and only one cartridge--the .50 BMG. This round is incredibly powerful, heads and shoulders away from the next nearest neighbor. This is meant to be fired in an anti-tank rifle. Only California has made it illegal. in 49 other states, you can buy a rifle that fires this round.
Still, if you are good shooter a .38 is a high enough caliber to make an attacker "dead".
It is all about shot placement. Any bullet will kill. .22 LR is one of the most deadly cartriges out there because of its tendency to fragment on impact, richocet around inside the body and not to exit if it hits bone.
The .22 is the smallest bullet
There are several smaller cartridges out there, some quite popular. The .17 HMR comes to mind. The .22 is probably the most common of all cartridges, though.
In addition, the process of getting a permit/license and then purchasing a gun is a long, drawn out process.
This is completely state dependent. I walked into a store and bought my guns with cash, walking out within 10 minutes. That's Missouri. California doesn't require near the background check that your state seems to, nor even one as good as Missouri, despite their ridiculous gun laws.
You can now legally purchase and M16 and guns like it.
Always could. The M16 is a machinegun and was never affected by the 'assault weapons ban'. The assault weapons ban did nothing. You could still buy an AR-15, just without a bayonet lug or flash suppressor on it--thus making the rifle
more accurate, ironically.
It used to be illegal to by assault rifles, but not illegal to own according to federal law. Now you can legally purchase one.
This is some jumbled thinking about the assault weapons ban and is simply incorrect, not to mention meaningless.
It's one thing to own a gun and have a permit to own, but it's a whole other thing to have a permit to carry a gun in public (like walking down the street or in major public venues)
This is also incorrect. MOST states have what is called an 'open carry' policy--meaning if you legally own a gun, you can carry it as long as you're not threatening people with it and as long as it's not concealed. Missouri is this way. You can carry a gun anywhere you want non concealed except places like schools, stadiums, courthouses, etc. California used to be this way until the Black Panthers marched on the capitol in the 1970s. Now, you may be thinking of concealed weapons, which generally require one to obtain a permit first. Only Alaska and Vermont do not require permits to carry a concealed weapon.
Jdurg--for your first gun, I'd recommend a Smith & Wesson .357 Magnum. I say S&W because they generally have excellent resale values if you take care of them and they make a quality revolver. Second, you can also shoot .38 special out of a .357 Mag revolver. Any of the magnum cartridges are expensive--and the .38 is a lot cheaper. Shooting can get real expensive real quick. Also, if you shoot .38 special out of the .357, try to use lead bullets (i.e., not copper-jacketed) because jacketed rounds will erode the throat of the cylinder over time due to the slightly shorter cartridge length. My dad owns an old .357 S&W--it's a blast to shoot. My friend owns a Ruger security six, a .357 in stainless steel that's great as well. It's a fantastic round. One of our friends owns a walther PPK--actually from WWII--his dad brought it back from Germany. He took it off a dead officer, and it still has the Waffenmarks on it. I don't like it much--it's very small and doesn't fit my hands well, but it's a really neat gun. Those came in .32 and .380--NOT .38 special. .38 special is a revolver load. The .32 and the .380 are much less hefty rounds than the .38 special. The 9mm is also a rather lean round when it comes to power--its great advantage comes in the fact that it is usually loaded into a semi-automatic pistol; this allows for greater firepower (i.e., more round capacity and higher rate of fire).
The .44 Magnum is great, but is very expensive and you won't want to fire it all day--it will get too heavy very quickly and it will beat your hands. I would not recommend it as a first gun. If you want the real Dirty Harry gun, it is a Smith and Wesson Model 29--blued, not stainless.
Next, the Remington 7mm is one of the hottest loades on the market. It's a real b$*%( to shoot. I've shot a .300 Winchester Magnum, and it's not a lot of fun either. I shot one 4 times without a recoil pad and broke capillaries in my shoulder.
As for my guns, in case you're wondering, I own an 8mm (7.91 x 57mm) Mauser K98 from WWII--still has the Waffenmarks on it. It's fantastic. I'll include a picture if I can. I also own a Colt AR-15, a 10mm Glock and a replica of the 1873 Colt Model P (The Peacemaker) in .45 Long Colt. The single action Colt is a fantastic gun to shoot. I'll post a picture of these, too, if I can.
Lemme know how it goes. Be happy to answer any questions you may about firearms in general. Happy shooting!
