This grip sleeve spacer adapter is designed for compatibility with Taurus G3 pistols when using ProMag 17-round magazines. The magazine sleeve spacer fills the gap between the extended magazine body and the grip frame, creating a smooth, integrated grip profile and a clean, finished appearance. The magazine adapter sleeve slides onto the ProMag 17-round magazine body and functions as a grip gap filler when inserted into the Taurus G3. Constructed from durable hard black polymer, this magazine sleeve spacer is heat and oil resistant and designed for a snug, secure fit. Each order includes one grip sleeve spacer adapter (Model ZF-P018). Magazine, firearm, and accessories are not included. This sleeve does not increase or modify magazine capacity and is intended for use with compatible ProMag 17-round magazines.
