Posted on |

  • Ed from USA asked:

    Can you put a laser pointer on it?

    • Mark from USA:

      There is no mounting rail on the stock 1377. You would have to mount the steel breech kit Crosman .177-Cal Steel Breech Kit,.... Then you can mount optics on the gun,

  • steven from USA asked:

    I'm upgrading my P1377 sight to the Williams Notch sight - in the notes says it will fit if its been modified with the AS2250-013 receiver kit. cant find that anywhere. can anyone point me in the right direction? thanks

    • Mark from USA:

      You need the Steel breach installed. Crosman .177-Cal Steel Breech Kit,.... Then the Notch sight should fit.

  • Mr. E from USA asked:

    Is the trigger adjustable

    • Mark from USA:

      Somewhat.

  • Thomas from USA asked:

    I am strictly left handed. Do the grips feel okay for a lefty?

    • Stacey from USA:

      Yes

  • Peter from USA asked:

    Can it be ship to Canada?

    • Tyler from USA:

      No

  • Richard from USA asked:

    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

    • Andrew from USA:

      You can buy an upgraded roll pin - search the web. Most of us who own this family of pumpers have done this mod for 1377, 1322, etc.

    • 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

  • Evan from USA asked:

    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

  • Mick from United Kingdom asked:

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

    • Stanley from USA:

      Doubtful this pistol can produce 600fps ?

  • Robert from USA asked:

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

    • Stanley from USA:

      This is a .177 caliber pellet pistol only.

  • Jasper from India asked:

    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 ?

  • txfish219 from USA asked:

    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.
