I want to install Meprolight sights on my Springfield Armory XDm 40 3" subcompact. I can easily see products for the 4" & 5" models but not finding any specifically for the subcompact frame. I saw a post that said that SA XD uses Sig grooves and I could use Meprolight sights for Sig on my XDm 3"?

Can I install these myself, or will I need to go to the city and use a gunsmith? I'm in a very rural area here.
