Available here is a Ruger GP100 chambered in .357 Magnum with a 4.2" barrel—offered as an open box deal in excellent condition. The photos show the actual revolver you will receive, featuring the classic brushed stainless finish along with the highly regarded GP100 rubber grip inserts with hardwood panels.
The GP100 series is famous for its robust construction, smooth double-action trigger, and heavy-duty frame—making it a top choice for both range days and personal defense. This particular revolver looks to have been barely, if ever, used and comes complete in its original hard case.
Everything has been function tested and inspected, though the revolver has not been test fired. If you have any questions about this GP100 or what’s included with the open box deal, feel free to reach out to Bay State Surplus! Don’t miss this chance to pick up a classic .357 revolver at an outstanding price!
