Just received my new weapon light - a Surefire P112D. It doesn't attach directly to the Picatinny rail unfortunately (comes with its own adapter rail). My question is: The latch to release the light housing from the adapter is very stiff (strong spring). Should I lube the contact points between the latch tongue and the adapter rails? Both are made from some type of polymer material. If that doesn't work, what about lightly rounding the upper-most edge of the latch tongue (Dremel work)?

Other than the hard to release latch, this unit is rock-solid, but a bit heavy.

i'm not sure about you personally...but when i got mine for my USP i had a hard time taking it on and off. after many days of playing around, i realized i wasn't doing it right. i was sliding that release tab all over hell and back...but when i pulled UP on it...the light came right off.

i don't mean to sound like i'm insulting your intelligence...but i'm just suggesting it as a possible solution. just check it out, in case you're messing it up like i was.

in the event you're doing it right...i would suggest the oil, and put on/take off...a BUNCH.

i'd save the dremel for the "last, by god, option."

cmc :)

cmc, thanks for the tips.

Dremel would probably make things worse :oops:

I did check with the shop I purchased this unit from.. Basically use the brute force approach. That is, pull straight up as hard as possible (the retaining spring is very stiff), verify the latch is depressed correctly (look just above the housing, right under the adapter rail), and carefully pull/push the housing forward off the adapter rail. Sheesh.. sore fingers the first time around. :cry:

Since both the adapter rail and the housing are made from plastic, it was also recommended that I not use any lube (my model, the Surefire P112D, is not totally waterproof). So back to practice, practice, practice! 8)
