Some do. For example, Denver has a ban on so-called "assault weapons", prohibits centerfire magazines of more than 20 rounds within city limits, prohibits open carry, etc.
Yes. Most cities have more onerous gun control laws than the United States does. However, many of them still have higher crime rates than the US does, and within the US, the states and cities with the strictest gun control laws often have the highest crime rates, such as Chicago and Washington, D.C.

Gun laws.
Your question asks for an opinion. My opinion is that gun control laws are based on a flawed belief that a person who will break laws regarding murder, robbery and rape will obey another law that says they may not have a gun. There are already about 20,000 Federal, State, and local gun laws on the books in the US. Gun control laws frequently do little except keep law abiding people from being able to defend themselves.
Most laws aren't enforced.
Some argue that gun control laws are ineffective because they primarily target law-abiding citizens, rather than criminals who obtain firearms through illegal means. Additionally, criminals can still find ways to access and use firearms even if stricter gun control measures are in place. Moreover, the effectiveness of gun control laws can vary depending on the specific policies implemented and the enforcement of those policies.
