Proud of the state-of-the-art technology represented by this advance, Colt included a green brochure marking its inclusion with every Model 1908 sold for a year after its introduction.

Additionally, in approximately the 280,000 serial number range, the left side slide inscription was altered to include the patent date for the disconnector, also known as the “Tansley Device”.

[2] The "Vest Pocket" was mainly produced with the famous highly polished lustrous Colt Carbona Blue finish, also known as Charcoal bluing.

Standard grip materials available included black hard rubber in both square and round top configurations, and finely checked walnut.

The Colt Model 1908 saw limited service with American and British OSS and SOE units during World War II, due to its nature as a small, highly concealable weapon.
