So, yesterday I bought a brand new xds .45 sub compact. I had a 4.25 xd .45 for a while and loved it, but wanted a smaller gun for better concealment. Any ways, I know a lot of company's make tons of parts for the xd and xdm, but I can't find any thing for the xds. I want a tungsten guide rod with the laser in it, a different trigger, and different grip safety. Any one know where to find any thing for the xds? Also, it has a factory fiber front sight, what do you suggest for a fiber rear sight?
