I currently have a TLR-3 on my full-size M&P and need something for the Compact.
I already have a TLR-1, an older Streamlight Light/Laser combo for a beater back-up bedside .45, and some other LED lights lying around.
Looking at:
Inforce APL Gen 3
Streamlight TLR-8
Leaning on TLR-8 right now because of Streamlight circuitry, heat-sinking, activation, no need to lock-out.
Big question I have, and I think I've answered is does the TLR-8 fit on an older generation M&P Compact?
It's listed for the full-size, not compact, but I saw one in the pics thread.
I shoot a minimum of 200rds per range session, usually 300/day and sometimes 800, depending on the course.
The TLR-3 has held up so far on the full-size M&P .40 shooting mostly 180gr Federal AE.
I'll be getting the TLR-6 for my wife's Shield.
