The X-type handheld flashlights are not for weapon-mounted applications. This has always been a given of these new handhelds.
So they may well eventually suffer physical damage as a result of weapon recoil.
My point was that "bare circuitry exposed to the batteries" was conflating without the context that we now understand relates to [the desire to use] misuse the P2X-B as a weapon-mounted light.
Bare circuity it is not. SureFire's electronics are conformal coated.
The circuity (PCB) featuring the positive contact for the battery without any intermediate physical component(s) is certainly the case.
SureFire could have designed this contact in any way they wanted and have experience with many different methods including ones like they have used for the X-type handheld flashlights. So to give these lights their "No-Hassle Warranty" SureFire would want to be confident that this design is capable of performing reliably and robustly for the applications and uses for which SureFire designed and marketed them for.
I agree it has the makings of a badass handheld.
