Marstar Canada: Assembly & Disassembly Information

Colt .25 Automatic Pistol (steps 1-6)

WARNING: Marstar assumes no responsibility for the accuracy of the enclosed diagrams for purposes of stripping or, assembly of parts of any firearm. Stripping, assembly, and reassembly of any firearm or component(s) thereof should be performed by a competent gunsmith. Marstar assumes no liability for any modifications, repairs or alterations performed on any firearm as a result of consulting theses pages. For reference purposes only.

Instructions below refer to part numbers listed on the Colt .25 auto exploded diagram. Please note the reference numbers therein do not correspond with the part numbers in our online catalogue.
STOP! Always 'clear' and inspect gun to ensure ammunition is not loaded or chambered before performing maintenance on this or any firearm.
1. Begin takedown by moving safety (23) upward to safe position. Depress magazine-catch button (28) and remove magazine (32). Draw slide (10) fully rearward to clear chamber. Safety will engage slide, locking it open. Rotate barrel (1) 3/8 turn clockwise and pull froward as far as it will go. Then rotate it 3/8 turn counterclockwise and remove from slide.
2. Grasp slide firmly and move safety downward to fire position. Ease slide forward off frame (11). Remove recoil spring (8) and guide (9) from frame tunnel. This is sufficient disassembly for normal cleaning.
3. To disassemble further, drive out extractor pin (2) with a pin punch that closely fits hole in slide. Extractor (3) and its spring (4) may then be lifted out. Pry out firing-pin retaining pin (5)( with a narrow screwdriver blase inserted under its elongated head. Removal of the pin releases firing pin (7) and spring (6).
4. Unscrew grip screws (20) and remove grips (19) (27). Rotate safety 1/2 turn from safe position and withdraw from frame. Drift out magazine-safety pin (25) and remove magazine safety (24) and spring (26). Insert magazine-safety (22). Pull trigger and lower hammer with thumb, until hammer-spring guide (17) stops against the pin.
5. Unhook forward arm of sear spring (14) from sear (12), and remove spring. Drift out hammer pin (15) and  lift hammer assembly (16) from frame. Drift out sear pin (13) and remove sear. Depress hammer-spring guide with punch, and withdraw magazine-safety pin. Then, ease out hammer spring (18) and guide.
6.

Drift out magazine-catch pin (30) to free magazine  catch (31), spring (29), and button. Drift out trigger pin (21), releasing the trigger assembly. Reassemble in reverse. Trigger mist be rotated forward to fully compress its internally located spring when the trigger pin is replaced.
