Issues with hit registration and lack of options

I have played almost every Battlefield game that has been released so I am quite familiar with the series. BF6 has been my favorite so far (Prior to this was BF Bad Company 2, Bf3 and BF4). There are a few issues that I would like to address that are absolutely frustrating to say the least. All the other classes seem fine to me but the sniper class is lacking severely when it comes to pistol options or power. The lack of a G18 Auto is quite disappointing but I could even live without that if the other pistols weren't so underpowered by taking 5-7 bullets most of the time to take someone out close range when they have any automatic rifle is quite sad and almost always guarantees you a death. Heck even if you could take a shotgun with you it would make up for it. The only gun that feels even remotely powerful is the 44mag and basically the only option if you want to stay alive when someone comes up on you but even that doesn't help that much as it's slow. The rest of the pistols feel like BB guns with rubber bullets. A 40 Glock should be able to take someone down quickly but almost die against anyone that isn't also using a pistol. I was in the Army and let me tell you this is not even close to reality or how these guns operate. Pistols close range should be able to take a target out quickly especially if you get the jump on them. Almost every scenario that happens is they have the time to jump up/around they could even dance a jig and still kill you with how long it takes to kill someone with a pistol. It feels really unrealistic with how many rounds it actually takes even hitting them in the head, which brings me to my next issue is headshot hit registration seems like it changes game to game. I can be fairly close (100m or less) or far away and shoot someone directly in the face and then not do any dmg at all or it does only 62 damage using the mini scout (this isn't just one rifle that has this issues it's all of them). Sometimes I can empty 5-7 shots into them knowing that I should have hit them but I get nothing. More than often there are games I where I have almost 20 assists due to this happening. This doesn't happen on all games it's random games I'll actually get headshots left and right without any issues but then i'll get a few games where it happens a lot. Shouldn't a headshot actually be a headshot or even hitting someone in the throat should be instant death? Shoot if you are at point blank range and get a no scope rifle shot should be instant death but you don't even get that. You get got by them after you still only do 62 dmg point blank. Please take a moment to look into this as it ruins the sniper class for me and others that I've talked to about these problems.
