No. You can go to a shooting range and shoot a gun without a concealed permit, however, you may be required to have some other type of paperwork. For instance, if you are a resident of Illinois, you must have a Firearms Owner ID card to purchase a gun, and probably have to have it to shoot one at a range.
Pull the trigger.
There is no best concealed handgun. There is a best concealed handgun for you! And, only you can be the judge of that. Size) Were on or about your body are you going to conceal the weapon? How big or small are you? Caliber) Find an instructor with access to a variety of guns in different calibers. Shoot 22 LR up to 44 mag and above if you choose. Determine what caliber best suits your physical and mental constitution. Style) Find an instructor with access to a variety of guns in different styles. Semi-auto, revolver, single action, double action, double action only etc. Pay attention to the different safety configurations. Determine what style handgun best matches your aptitude for mechanical complexiety. Once you can answer these questions, you can start shopping for a handgun. Once you obtain a gun practice regularly. After decades of experience with guns "my" best/regular carry gun is a glock 26. It is small, high capacity -13 rounds with extended magazine- decently potent caliber 9mm (particually with high performence JHP bullets) and completely reliable. 100% reliable in my case. I owned the gun since 1996 and never had a failure. In the end it is your choice. Do research and get practicle experience, eventually it will become completely obvious to you what the right best concealed Handgun for you will be. If you are going to ignore this advice and get a handgun anyway. I recomend any small framed SW revolver in 38 special. These revolvers are small, easy to shoot, completely reliable and "practically" idiot proof. Perhaps a Smith and Wesson 638. My second favorite concealed handgun and my wife primary concealed weapon.
No.
No, you cannot.
Laws are complicated, which is why we have lawyers. So yes, you can use a legally owned handgun to prevent a crime in progress, even if you do not have a license to carry a concealed weapon. However, if you shoot someone, or kill someone, you may still be accused of having used excessive or unnecessary force. Even if you do not shoot anyone, but you do discharge the gun and damage some property as a result, the owner of that property may sue you. So I won't tell you that this is entirely free of risk.
I'll give the answer a shot (no pun intended). It depends on the circumstances. The handgun permit and handgun permit laws allow you legally carry a handgun, but the handgun permit laws don't specify when you can use the gun. When you can use the gun is covered under the state's deadly force laws. So, if a snake is attacking you and you have no other choice but to shoot it, it's probably ok. If you're talking about randomly shooting snakes that you see on the side of the highway or somewhere, probably not.
A typical 9mm handgun has an effective range of around 50 meters, but can potentially reach distances of up to 2 kilometers depending on the specific firearm and ammunition used. However, accuracy and lethality greatly diminish at longer distances.
Can I shoot 380acp caliber out of my 32 pistol?
Yes.
500 m or so IIRC
If you shoot enough of them you get the punisher handgun for free from the merchant.
