There are two types of 1911, bushing barrel and bushing less (bull) barrel 1911s.
Of the two types, there are three basic types of recoil systems manufactures could use in their 1911s.

Take down tools found on this site are not designed for any specific 1911, rather they are designed for a specific type of recoil system.
