Exchanging sights on two "like" firearms.

[Great-Kazoo]

Hello Good Folks, I hope all finds you well. I have a quick question, which I hope does not seem to rudimentary or naive as I've always had other people do the work but due to circumstances and moneyflow, I think I may just give it a shot myself. So...

I have a G19 and a G43.
The G19 has night sights on them.
I would like to take the G19 night sites and put them on the G43.
Then I would like to install a red dot on the G19.

1. Is this possible? I'm assuming yes since same brand, just not sure since the G43 is slightly slimmer than the G19.
1A. Is there a manual somewhere that tells me how to accomplish this.
2. Are red dots on pistols "suppressor height"?
2A. The red dot is not purchased yet, what are decent choices? I've got my eye on the Vortex but it is pricey (IMO).
3. When I fubar it all, does anyone have a suggestion on whom to take it to and what the approximate cost might be?

Thank you.

If you want a RDS to align with the sights, you'll need to buy suppressor height ones. If you're going to mount a RDS you'll need an adapter plate that will go in where the rear sight sat. IF you don't have a slide already cut (MOS style) for a RDS.
SO. you either need the plate and no sights, or run sights and no RDS.

I haven't seen any rear sight RDS adapter plate except for what Burris offers. That will limit you to a Fast Fire 3 RDS.

Swapping out sights isn't hard if you have the tools to do it. If you don't have the front sight super skinny nut driver and rear sight tool. It might be more cost effective to $$ someone.
