Colt Model 1908 Vest Pocket Hammerless .25 ACP - Disassembly
The arm must not be cocked when about to be taken
apart. Remove magazine. (Be sure to look and see that
no cartridge remains in the chamber.) Grasp the
pistol in left hand as illustrated, and draw back slide
until within 1/16 of an inch from end of receiver. With
right hand give barrel one-quarter turn to right. The
slide may then be drawn forward and barrel can be
removed from slide by giving it one-quarter turn to the
left and permitting it to drop out rearward. (When slide
is removed, care should be taken that the Slide Lock
Safety is not pushed upward as this will release the
Slide Lock Plunger and Spring causing them to fly out
and become lost. [NOTE: this is only true on models made
after 1916. Before 1916, a small leaf-type spring along
the cam of the Slide Lock Safety was used to provide
tension.]) The firing pin, main spring and guide are
readily removed from slide, as are also the retractor
spring and guide from receiver.
