Does the mod 2 have a distinctive reset for the trigger?I had much the same issue until I impulsively purchased an XD-S Mod 2 in 9mm with the factory supplied red dot.
I won't go into the quality of the Crimson Trace red dot although to date it's held it's own.
Long story short I ordered a Blade-Tech IWB holster for it. Made some small modifications (still modifying it) to it and that is now my EDC and has been for several months.
Very comfortable, easily hidden and quick access.
I will at some point upgrade the optics. I do have to admit out to 25 yards even with the lower end optics I'm impressed.
Just throwing that out there.
If it doesn't, see if the PRP kit will fit the gun.
My wife has an original XDs and there was no way to tell when you hit the reset, I installed the PRP kit in the gun and its night and day different, well worth the money in my opinion.
I have zero experience with the gen 2 gun so I'm not sure if they have a kit for it, or if it even needs one.
