The guvment just loves screwing with you. They're probably sitting around, looking at your application and laughing their asses off with that God like feeling of control over you. I mean, for Christ's sake, it's a piece of hearing protection equipment.
I'd say that as long as this adjustment is done immediately and no one sees the stock in it's unpined configuration, then, no harm no foul. Keep in mind that during the few minute that the stock will be adjustable you will be in violation of the letter of the law. Caution and silence would be advised here.
Welcome scposubs. The new trend in tactical 22s does indeed interest the kids and helps get them away from the video games and learning some real world skills.
Probably not. I wouldn't have purchased this pistol if it hadn't come with a 9mm conversion. On a side note, since the .22TCM is adapted from .223 brass, primers and bullets, with a set of dies you'll always be able to make your own .22TCM ammo. I haven't seen the dies yet though.
I used to live in Alaska and firearms (semi-auto, bolt or revolvers) will refuse to operate in the temps experienced there. Everyone lubed their firewarms with dry graphite powder. It's very messy and gets everywhere, but it works in the 35 degree below zero temps I saw up there.
Fired the 22TCM ammo for the first time last night. Wowzer! Huge bang and muzzle flash. Very low recoil. Ammo ran through it like shit through a goose. Most fun I've had in awhile.
