Just to make sure I'm up to speed, the TLR-2IR is IR illumination and visible red laser, and the TLR-2IRW is visible illumination and IR laser, right?
I use a 30mm 720nm IR bypass filter on my PVS14s. I never take them off. When using them, a 5mw red visible laser is good out to 100 yards with no IR illumination and 30 or 40 yards with IR illumination - it gets washed out. There is zero bloom with or without IR illumination. With the same filter, a .7mw IR laser is basically useless under 100 yards with no IR illumination (has about a 12" bloom at 50 yards) and is OK at 50 yards with IR illumination with about a 4 inch bloom.
If using the filter, and mounting this on a pistol, I think I'd just go with a regular TLR-2. White light and visible red laser the 98% of the time you're not wearing NODS, and when you are under NODS, just using the red laser is good to go at pistol ranges. I use the TLR-1IR (no laser) on a carbine, and it is almost as strong as the Streamlight SuperTac IR- same output, just a smaller bezel. Streamlight's IR LEDs do have a faint red glow, as I think they use 850nm LEDs instead of 940. It's not much, but I have had deer notice it at 100+ yards. SkyPup suggested a 850nm IR filter, and I figured out that a 30mm 850nm IR filter fits perfectly into the TLR-1 and replaces the glass in the light just right and eliminates all the red glow that is visible to me.
