The Pearce Grip Extension (part no. PG-MPS45) replaces the magazine base plate on the S&W M&P Shield chambered in .45 ACP, adding about three-quarters of an inch of gripping surface without altering magazine capacity. Pearce Grips builds this extension specifically for the standard .45 ACP Shield magazine — it is not compatible with the 9mm or .40-caliber Shield, and it should not be used on an already-extended magazine. Confirm your exact model and caliber before ordering to make sure it’s the right fit.
