Wow...but nothing on suppressors?
And what's with #3 (Reserved)? Just so they can add something later?
not sure on #3, maybe they leave that there in case some completely new type of firearm comes into being, like lasers or something, haha.
I also found this:
PA Game Laws Sec. 2322. Prohibited devices and methods.
(a) General rule. - Except as otherwise provided in this title or commission regulation, no person shall hunt, kill or take or attempt, aid, abet, assist or conspire to hunt, kill or take any big game, except wild turkey, with any of the following devices or methods:
(1) Any device other than a center-fire or muzzle-loading firearm or bow and arrow.
(2) Any automatic or semiautomatic firearm, except that any semiautomatic firearm modified to permit one shell in the chamber and no more than four shells in a magazine may be used by a person who suffered an amputation or lost the total use of one or both hands.
(3) Any firearm propelling more than one projectile per discharge.
(4) Any projectile which is not all lead or which is not designed to expand on contact.
(5) When any big game is swimming.
(6) By any other method or device which is not specifically authorized or permitted by this title or commission regulation.
Apparently #6 can be construed as prohibiting suppressors since suppressors are not on the authorized/permitted list.
although this is specifically big game, like deer.
Although I also read somewhere that said if there is no law against using suppressors, then they can be used.
