For night sights, I would favor the Meps over the Trijicons. For competition sights, the selection becomes quite narrow. Heinie and Warren would be my choice with preference to Warren. Haven't checked recently to see if Warren is offering his Sevigny sights for the P-30, yet. Let the purpose dictate the sights you use. You really can't go wrong with either Meprolight or Trijicon. I've been using Meps on my pistols, but they came factory equipped.
