Customers Q&A on Crosman 1377C / PC77

There is a hollow pin below the front site that the cocking mechanism hinges on. The cocking action causes the pin to move away from one side. I have been taping it back into place so that the won't slip out. Is there a fix for this? Thank you, Richard

• Bros80 from USA:

  You might want to try to out the pin on a hard surface and insert a tapered punch in each end and lightly tap it with a hammer to "mushroom" the ends of the pin

I know there is a stock I can buy for it, but is there a way to add a barrel extension to this pistol?

• Jacob from Canada:

  You can buy longer barrels to replace the stock barrel up to 24 inches long in .177 and .22

Can this Air pistol be shipped to the UK, kind regards Mick G

• Stanley from USA:

  Doubtful this pistol can produce 600fps ?

Is this a pellet air pistol or a BB air pistol or both?

• Stanley from USA:

  This is a .177 caliber pellet pistol only.

How long can I leave it pumped -say 7 to 10 pumps - without damaging the integral parts ?

• Stanley from USA:

  I wouldn't leave it pumped for more than an hour ?

When not using the 1377C or other muti-pump gun, should you leave it pumped? If yes, how many pumps?

• Stanley from USA:

  Joe, this information is not in the manual because if it never broke down they couldn't sell you repair parts (its about money dude? )

• Joe from USA:

  I emailed Crosman and was told to leave gun with one pump in it. Why this was not in the manual? Maybe a safety libability issue (if a pellet was left in the chamber).

• Stanley from USA:

  1 to two 2 pumps will work i periodically check mine to make sure there still holding air.

• michael from USA:

  Probably should I personally didnt know this until recently, mine is almost 20 years old, stored unpumped and used occasionally and it still functions well.

• Tyler from USA:

  Leave one pump in the gun when not in use.
