Well for many people its hunting or home defence, for me I'm just trying to find a new hobby. Maybe do target shooting and eventually skeet shooting. If I'm any good I could enter competitions. 

How do you like the Glock 17? My friend that I took all the courses with is interested in that gun. 

Yeah I own a few guns, mainly hunting rifles. I started watching Topshot on Netflix and it has really got me back into the mood of shooting.

one question, do you allow to own automatic weapon such as ak47,acr, or g36c in the US

Yep.  You can own nearly any weapon as long as it isn't full auto.  AK 47's, AR-15's (civilian equivalent of an M-16) and other assault weapons are just fine.

Don't own one, but I am looking into getting a gun for the purpose of home defense. For anyone here with some experience, what would be a decent gun for that purpose? Keep in mind that I don't have any real experience to go on here so whatever it is it has to be beginner friendly.

This would be something just for home defense and fire range use so I have some comfort level actually using it.

I own a Sig Sauer SP 2022 9mm handgun, a 30-06 cal. rifle with an 18 power scope (I'm pretty accurate from about 350 yds in), and a 12 gauge pump-action shotgun.  I recently got my concealed carry permit so I can pack heat.  I'm looking into getting an AR-15 kit and assembling it myself.  Fun gun to shoot.

To the person that asked why we love guns in America?  First of all, only about 25% of the American public are gun owners and far less than that have concealed carrry permits.  But to answer the question about why we love guns, it's hard to explain to someone that either didn't grow up around them, or isn't currently around them.  It's exhilerating to fire your weapon down range on target or to hunt prey with it.  In my experience the difference between gun owners and non gun owners is how they view a weapon.  My 5 year old son knows more about my 9mm pistol than my neighbor does because I've taught him about it and he's seen me shoot it.  He knows what it is capable of and not to touch it.  Most non gun owners are afraid of guns.  Guns are scary to them because they haven't been exposed to them.  I respect what my guns are capable of but I don't fear them.  Hopefully that makes some sense to you.

I really like my Sig Sauer 9mm.  I looked for a couple of months before I settled on it.  It's a full size pistol but can still be concealed, though probably not a big deal to you unless you plan on carrying.  People will argue over the caliber and it's knock down power if you ever needed to use it for home defense, but it is more about the ammo you use than the gun.  I prefer the 9mm over the .45 because I shoot a much tighter group due to the smaller recoil.  Also my mag holds 15 rounds versus the average .45 which holds around 8.  I would recommend a Single Action pistol whatever you choose.

If you want a really safe gun you might look into the Springfield XD.  It has 3 safety mechanisms and two of which need to be pressed simultaneously in order for the gun to fire.  My Sig is more of a military style gun in that once I pull the slide back and pop one in the chamber it's ready to fire.  No safety switch, though it does have a decocker.  I like the polymer grip and light weight of my Sig as well.

Ultimately I would see which pistol feels the best in your hand.  The grips, sights and frames all make a difference.  Have fun!

@Marks, like I said, I'm not a gun fanatic so I can't tell you how it compares to many different weapons. I've shot a 9mm Taurus, the 40 Cal Sig, and the Glock 17 and let me say that I prefer the Glock BY FAR. Trigger pull feels perfect, unlike the other two whose triggers require so much effort that they can actually throw your aim off. It's very reliable and doesn't seem to recoil at all, either (Sig hurts my wrist when I fire with the weak hand).

I qualified with the Glock with a 98% accuracy (out of 30 rounds, all of them hit center of the target--one round was barely below the box in the middle). I shoot the Sig far more often and I'm just happy if I can get everything in the grey (I'll have to post a pic of our targets so you know what I mean. I think they're TQ-19 but I'm not positive- -and I'm posting from my phone, on my job). I love my Glock.

Here's the guy.  I know him very well.

I'm pretty jealous. If I could move anywhere in the world it would be Canada.

There are some details I forgot, shotguns are not allowed to hold more than 2 shells without reloading (the shell in the barrell doesn't count), so if you bought a pump action shotgun in the UK, you could only fire 3 rounds before having to reload. Sawn-off shotguns are banned too.
