*STI is dedicated to ‘Continuing the Evolution of the 1911′ and we periodically implement ‘rolling changes’ to our product specs. While we do try to keep the website and catalog photos as current as possible, there is often a lag between an improvement being implemented and being reflected on our marketing materials. For this reason, all entries are representative only and subject to change without notice.
