hey, I'm gunsmith in Darlington SC. there is a cross pin called the firing pin retaining pin. its under the extractor which is held in with a pin through the top of the slide.
the retaining pin on spring loaded (inertia) firing pin is usually loose fit and shouldn't be hard to get out. pushing the firing pin forward to take spring tension off the retaining pin may aid in getting it out but like all things nothing is ever as easy as it should be. good luck , i have one driving me up the wall too.

This is best left to a gunsmith
10-1000 USD without more of a description.
IMHO, best left to a gunsmith to remove it.

Google "colt junior"
Best left to a trained gunsmith
Your colt junior 25 auto was produced in 1962.
Metal, plastic, rubber, firing, non-firing?
Knowing the firing order of a car's engine can help diagnose engine problems. The firing order of a 1987 Dodge Colt Vista is 1-3-4-2.
Depends on what is the most dirty. If you have used it near dust recently, be sure to remove the firing assembly and firing pin and clean those first, because they are generally the cause of jams.
