I have the same issue which forces me to shoot left handed. The same condition makes it hard for me to use magnified scopes. I just sometimes struggle to get a good sight picture.
However, with a red dot, I have no issues... besides still needing to shoot left handed. I have no problem quickly acquiring the target. I have removed my backup folding sights as I just never use them. My old eyes don't sight thru them well & they just take up rail space. For me and my eyes, a red dot is the best option & when I need magnification, I add on my flip to side 3x Primary Arms magnifier.
I suggest starting with a TRS-25. It is a great optic at a great price. Then if you later find a little more jingle in your pocket, then you can add something like the Aimpoint Pro that I use... and love.
I have a TRS-25 sitting around & if you wish, I can send it to you to try out, assuming you don't have access to one locally. Send me a PM if you want to do so.
