It's time to replace my stock G19 sights and was curious if anyone had any experience with the AO Big Dot sights?  Are they any more or less accurate than standard 3 dot sights?

I have installed these sights on several different handguns for clients. Generally, the clients are older people with the nearsighted problems that come with old age. About 1/2 the clients liked them and will use nothing else. The other half did not like them as they effectively covered up the target and did not allow for shooting optimum groups.

I personally do not either need nor like them. But they are a solution for some. IM if any questions. Charles the Gunsmith.  

Thank you.

I have one installed in Sig and it works fine.

I can't get that 1 hole accuracy at 5 yds, but I can blast Coke cans at 30 yds without problem.
