The TruGlo TFX TG13MP1A does fit the SD9VE, just oil it up punch it off and tap back in the TFX, yes I know it says it won't fit, it does. Was more of challenge to get original front site to move/remove than it was to install TFX. The TFX is well built, all metal, encapsulated, and bright 24/7. Now off to the range to sight her in.
