I think that is a good question. Glock says not to introduce any lubricants into the striker channel. In the Lenny Magill video the Kahr striker is clearly lubed and Lenny says that is a good thing. I didn't see any kind of plastic channel liner in the Kahr like the Glocks have but the reason Glock says not to oil the channel is to avoid any gunk buildup (and maybe hydraulic friction) which would seem to be applicable to any striker fired gun.
