      It came pretty fast the packaging was pretty good as well but the only thing I’ve noticed is the way it scratches up really fast other than that it’s definitely great product highly recommended!!!!

      PSA Rock 57 7 rd. magazine extensions

      Posted by Robert P on Apr 27th 2025

      The 7 rd. magazine extension for the Palmetto State Armory Rock 57 us a very well built and robust magazine add on, being machined from a block of aluminum, it should be! Installing the extension is fairly easy, but the spring is a bit tricky getting pushed up into the magazine body, because of it's length, and then sliding the extension over the magazines original spring plate lips, takes a bit of finger dexterity,but with patience and some finger manipulation to guide it into the body, and installing the retaining set screws (don't forget the Locktight !!!), it's all down hill from there. One other thing to watch out...when loading rounds into the magazine, you may have to remove them a couple or more times to get the follower positioned properly, and you may have to use a slim object, like a wooden paint mixing stick to "set" the follower in position, after that, you're ready to go!!!
