Having issues returning your slide forward when loaded or even when no magazine is present? Tyrant has made slight geometry changes that now allow the slide catch to also function as a slide release (no slide release function on empty magazines). This means no more needing to use both thumbs and no more needing to manipulate the slide by hand in order to return to battery! Tyrant's Sig Sauer 365 extended slide catch/release adds surface area and a raised texture that greatly improves usability for all! It is the perfect upgrade for concealed AND competition. Never again will your thumb slip while manipulating your Sig Sauer slide release! RSR -
