What to do with G19 MOS

I may be the newest newbie to ask a repetitive question, but I went ahead and bought the g19 MOS for concealed carry thinking “well, if I want to add a sight later, I can.” Now I’m wondering if for conceal anything makes sense. Does anyone have a suggestion for something to add? I’m likely to add a flashlight when I have the money, but I don’t know if there’s any other reasonable things to add for me. via /r/CCW http://bit.ly/2ERDztI
