What type of handgun and bullets are good if I want to shoot myself in the heart, considering I don't use hollow points?

[iwantitalltoend]

I would like a handgun because I think it would be easier for me to control it and aim correctly at my heart instead of a bigger gun such as a shotgun for example, a bigger gun means a bigger recoil so it might be harder for me to control it, I also don't have experience with firearms and I'm not an expert on the different types of guns and bullets, but I read about them and watched videos on youtube about guns so I'm familiar with how to shoot guns, different types of bullets etc, but like I said I'm not an expert. Would handguns such as 9 mm, 45 or 357 be good enough for this? For example I was thinking about a 9 mm gun because it's a popular type of gun, many people use it and from what I read on the internet it's not difficult to control when shooting, it's a good gun for people who haven't used guns before while also having strong enough bullets to be lethal. Hollow points aren't available in Europe so would other type of bullets be good enough if I use a 9 mm gun? When I'm saying other type bullets I mean lethal bullets, such as Full Metal Jacket, the ones with lead and copper. Are they good? What other type of bullets would be good enough for this? I know the most important thing is to aim correctly and hit the target from the first shot, but like I said I want a gun that's not difficult to control while also having strong and fast enough bullets to kill me. The heart is located slightly on the left side behind the sternum, and behind a few ribs, but I would say it shouldn't be difficult to aim at it because it's a big enough organ. Many people killed themselves by shooting themselves in the heart with handguns and also with bigger guns but I think it also depends on the type of bullets used. I'm looking for opinions and more informations about this, any opinion and information would be helpful
