Hi everyone, I have been looking at the newly released Dagger Pistol from Palmetto State Armory. https://palmettostatearmory.com/palmetto-dagger.html https://palmettostatearmory.com/psa-dagger-9mm-compact-pistol-black-black-910111111.html The Dagger seems very popular. They are already out of stock. I'm thinking about getting one when they are back in stock. I have a question: Why does the trigger look like it has a sort of hinge on it? Does it have some kind of trigger safety like a Glock? Also, can the white dot sights be removed and replaced with night sights (I'm assuming that the white dots don't glow in the dark)? Thanks for any replies!
