20 Most Recent Crosman 1377 177 Single Shot Air Pistol Questions & Answers

bought a gun with a bent barrel so bent that the sights cannot be aligned to get to right

if you dont have a cleaning rod for it you can go to your local bass pro/cabelas/outdoors store and get a cleaning rod for a .17 caliber for fairly cheap. you should be able to push the pellet out or clean it if there is dirt or grime in it. and make sure you use the right caliber pellet! (:

yes it safe to shoot bb,s in the 1377 pump pistol,i have 3 of them they actually shoot true'er and with more vilocity

Sounds like the O-ring inside the pump mechanism is bad or going bad. You can try to add a little lubricating oil and see if that can stop the O-ring from leaking.

Hope that helps!
Please don't forget to rate.

Hi orichtero...
Take the air gun to the nearest roller bearing seller, they will have o rings also...they will be able to fit the right o ring for your gun for you
Please take time to rate me

Yes. This is as simple as replacing O-rings and seal bushings. you may get out for less than $5 worth of supplies. Just be sure to label everything as you take it out of the gun and lay out the parts in the order you removed them. this will make reassembly MUCH less painful. Oh yeah.... remember to clean and oil the parts as you put them back in.

Single shot.

Hello,

Unfortunately, there are no parts available for your Benjamin Sheridan Air Pump Pistol that I know off. But I would suggest you contact the manufacture of this pistol via e-mail or phone and ask them if there actually parts for this pistol. They might have the parts or send you to a deal where the parts can be gotten (if available).

I think the manufacturer is the best to contact as they might be of help.

Good luck.

The pumps seal is bad so take it apart and cut a piece of leather out to fit
Coat the leather with Vaseline and it will operate just fine for you

Well that takes me back! I have an old Daisy 1200 -- essentially the same pistol in a different brand.

My Daisy has a hand-turn screw to hold the CO2 cartridge in place, and you have to tighten it quickly until the leaking stops. It does this by pressing the cartridge up against a nylon washer to form a seal (and of course pushing it into the piercing pin to get the CO2 out!)

With age, I'd expect that nylon washer to get stiff or crack, making it harder to form a good seal. You don't need an exact replacement part, but if that's happened to yours then you will need to replace it with something more-or-less the same size as the original.

The Next PX 6.0 uses a 27.2mm seat post.
