I have a Sig Sauer 229 9mm that needs new sights. I'd like to put some Ameriglo SG-504 Defoor sights on it but I'm having trouble figuring out if they will work or not. Called Ameriglo and they didn't know....their website says they will work on any Sig that uses a #8 front and #8 rear. I don't speak Sig...anybody have any experience with this?
