The Little Sister Everyone Forgets About
Sig Sauer’s lineup is full of shining stars, but sometimes its nice to see some of the lesser known siblings get loved on by the community. The PS522 is just that kind of release, a project made to resurrect a relatively unknown rifle for the sole purpose of enjoying it.
Delivered by Vinh Nguyen, a legendary developer in his own right with nearly two dozen releases to his name, this collectible is sure to excite any Sig fan.
