We know that under Federal law, an AR pistol over 26" OAL becomes the same kind of "Other Firearm" as a Mossy Shockwave or a TAC-14. Admittedly State laws will vary, but I was wondering how many states have an upper-length limit on a CCW-eligible pistol?

Here in WA, I've only found RCW 9.41.010 to go by:
"(20) "Pistol" means any firearm with a barrel less than sixteen inches in length, or is designed to be held and fired by the use of a single hand.
Big two punchlines:
1. Does exceeding 26" make it no longer covered by my CPL? Right now with a 10.3" barrel and an Vltor A5 tube (3/4" longer than standard) I'm at 25.925" bare, 27.75" with brake, and another inch and change of growth coming from the LAW Tactical sidefolder when I get it bought.
2. Do I measure from end of buffer tube to the muzzle crown, or the end of the (not pinned) brake?
