I'm getting ready to put some new sights on my carry gun. My question is how do most of you change sights? Do it yourself, send slide off to have them installed or use someone locally? I've never changed sights before but pretty sure I can do it. I may be changing up to 3 sets over the next several months so I'm really considering buying an alignment tool. Who would you recommend in the Hammond- Baton Rouge area for installation.
