Pearce Grip Frame Insert for S&W M&P Shield 9mm/40

This unit fits in the bottom rear cavity of the M&P Shield utilizing a friction fit to secure it in the frame. Made of a high impact polymer, this insert is designed to keep out dust and debris as well as finish off the overall look of the frame. The insert is equipped with two trimmable ribs to allow for variation in frame cavity sizes. On most frames with the manual thumb safety these ribs must be removed for proper fitment. These are simply trimmed flush with a sharp knife. Note: Does not fit 45 ACP models.
