As the title says, gonna be picking up my first handgun soon since my wife has finally given me the ok to get one.

I'm eventually planning on getting my CCW so I'm leaning towards the glock 48 MOS. I really like the way it feels in the hand compared to sig p320 or 365 can't remember which one I tried at the range. My only question on the handgun itself is would I be better off going with the tried and true G19? Also if anyone knows where I can find a better price on the 48 MOS online please let me know

Second question, is this a decent choice for a quick access safe ? I already have some products in the wyze ecosystem and I really like that you have 4 different ways to access it. Im not trying to prevent theft with this safe, more interested in secure storage that'll keep it safe from prying eyes and something that I can access quick should the need arrise.

Third question, light or sight first? I've already settled on what light ( Streamlight TLR-7A ) but I'm undecided on a sight. Was going to get the sig romeo zero since I love the romeo 5 on my rifle so much but reviews I've seen are all over the place. Is the sight worth trying or should I just bite the bullet and try to get a holosun 407k?

Thanks in advanced for taking the time to read this and help me out

Edit: Just to help discussion, I'm in a 10rd capacity state. Forgot to initially state that.
