Precision manufactured from hardened 17-4 stainless steel (compare to MIM molded factory SIG part) and finished in durable black Melonite for wear resistance.
Extended magazine release button is anatomically optimized for easier and faster release as used on true competition pistols. Angled head matches the natural curve of the thumb for positive contact and control.
Please note: only the extended button itself is included - you will need to re-use the small factory 'wedge' as well as the spring from the original magazine button.
