Feddersen can make your Glock™ 23 more accurate with a match grade precision-manufactured gun barrel. Our drop-in replacement barrel is the instant upgrade you have been looking for. No tooling or retrofitting required. Available in matte or polished stainless steel. A threaded barrel option that connects silencers is also available.
