I bought one of these at the flea market cheap because it wouldn't pump up. I took it home and put about a teaspoon full of 91% alcohol in the pumping mechanism and let it soak for a day to let the seals swell up again. I dumped the alcohol out and I sprayed some silicone spray in the mechanism. When I fired the gun a lot of black gunk came out the muzzle for the first few shots. The gun holds air pretty good now. I may put an upgrade piston in it in the future but for now I'm just having fun shooting it. Thanks for the videro.
Man you have cool guns, I hope you keep getting more subscribers. Anyway, I had one of those pistols back in the early '80's too. I don't have it anymore, I honestly can't remember what I did with it. Maybe it quit working or something, I don't know. But I do remember how much fun it was, and how accurate it was. I do still have my old Crosman 38T, which is a 6 shot pellet revolver that uses CO2. It wasn't as powerful as the 1377 but it is a lot of fun. It quit working a few years ago and I found a repair/seal kit on ebay, and repaired it so now it's shooting again!
Thanks! It’s been fun getting all of them out and shooting them again. Some of these guns haven’t seen the light of day for literally decades. You’ll have to get yourself a new 1377 or 1322 to relive some memories! 👍
That’s really cool bud, I grew up in Wisconsin and as a kid we shot the same exact pistol and they are reliable and fun to shoot! Good video thanks! Brought back many childhood mems hehe
Thanks! I really like these style guns. I didn’t realize until recently that the pull knob cocking action on this model dates back to the Crosman model 101 rifle that used a similar system to cock the gun.
I just got a suppressor kit from Buck Rail for my 1322...it comes with the adaptor, can and thread protector...it's very functional...and looks pretty cool too
Nice! I don’t remember what labels came on what boxes over the decades. I’ve just kept many of the airgun things I’ve had as a kid. It’s fun to share them on TH-cam.
@@airgunsofalaska I believe but don't quote me but I thought there was a picture of a snake on the cover maybe they were call copperhead but that's 40 years ago I could be dead wrong
I loved that pistol. Got mine in 1984, what I loved about those was the magnetic probe there. You could shoot bbs or pellets. The one now only pellets.i had the leather holster for it too. Just a great air pistol. The only draw back. Not very backyard friendly, has a pretty loud pop to it. Out in the country though, no big deal
My first airgun. I had the stock, my cuz had the holster. Crosman pellets at the time were called " Pells" and came out with the nicer ones a year or two after I bought it. It was stolen along with a Crosman 357. I received a new 1377 from my mom about ten years ago with the plastic breech and stock. took it out a couple months ago and something happened and the breech failed at the screw. I looked into fixing it and found parts on eBay for it and it's back running for under thirty bucks with an upgraded port . And actually looking forward to a few other upgrades. While searching for parts, I found a brand new, still sealed, original steel breech 1377 form the early eighties. I'm in heaven at this point and have not set it free yet and admiring it like the kid at Sportmart in 1984. There is something enchanting about the breech cover and pulling back the hammer, over just sliding the bolt back on the newer ones. Happy shooting and thanks for the video!
Didn’t know the history but I bought one in ‘81. Loved it. I’ll have to dig it out. Might still have some Crossman flat nose pellets. We used to turn them around, perfect hollow points!
@@airgunsofalaska I found it, 1377 American Classic .177, plastic breach # 881240545. I’m sure I bought it in ‘81 but could be ‘82 I guess. Did some indoor ballistics testing last night (forgot how much fun that is!). Starts to hiss on about the fourth pump so, needs a kit but still very accurate!
@@rong4189 Right on! I’m pretty certain yours is an ‘81. Your serial # indicates it was built in August of 1981. I’d try oiling it with Pellgun out and keep shooting it. There’s a chance it might revive the seals and it’d work properly again. If not the parts are available to reseal it and there are videos on line with how to do it. I’ve never resealed one of these so I don’t have any first hand knowledge but I did replace the pump handle on one and driving out and reinstalling the roll pins was a hassle. I thinking the big roll pin at the pivot needs to be driven out and then the pump linkage and piston can be removed. I need to do the same thing on my ‘81 Crosman 760 as it also has the hiss and that one won’t shoot full power.
@@airgunsofalaskaLittle update, got a reseal kit and since I’m a hot rodder, watched a few videos on porting the valve with a Dremel in the transfer port area to gain 100+ fps, did that, skinnied up the valve stem in the tp area to help airflow, and that’s about it. Shooting it afterwards, I had mixed reviews. Bought an economical chrono (seems to work pretty good, checked it against a new 1322, rated at 460, I get consistent 460+) and I’m hitting 500 fps at ten pumps. Wish I had the chrono before the rebuild, but oh well! So now I’m trying to find accurate ratings on a new 1377 to compare, but I’m seeing 450 to 600+ fps. Oh well, it’s so fun either way!
My older neighbor kid had one of these in the 80s and i remember at sprouse ritz they sold them for 50 bucks which was alot of money back in those days haha crazy how they sold pistols and rifles in those types of stores back then. It was like a dollar general on steroids.
@@navajorezathlete1202 I’m pretty sure this one came from Kmart. A bunch of my airguns I got as a kid came from there. On eBay you can see prices for Daisy guns in ads from the 80’s. It’s pretty crazy how expensive they were back then after adjusting for inflation.
Where do you find reference material for these guns? I have several rifles and pistols and would like to know about when they were manufactured and what changes were made from year to year. Thanks for the video.
I just end up Googling around and then comparing the info I find for consistency. Seems like the info often pops up in airgun forums. Daisy, Crosman and Benjamin seem to have a lot info available due to their longevity and popularity.
@@airgunsofalaska I will have to send you an image of that, I don’t know the exact name of the item. But the the main washer which is used to pump the air in the cylinder..!
I would shoot crickets that got into the house. Was very accurate and aim point was at the top of front blade. Many crickets were taken out as they snuck along floor. That was 1984....
At 20 paces or so I could hit the end of a 35mm film canister no problem (about the diameter of a quarter). And the thing had decent power..at ten pumps pellets would go through both ends of a 35mm film canister at 20 paces..also clean through a spray paint can at ten yards or so.
I had the exact same model air pistol. Very accurate and a fair amount of power for a pneumatic air pistol. Sold it to a young shooter some years ago. Now I have a Crosman 'Vigilante' CO2 powered air revolver while it is fun and useful for revolver firearm practice; the build quality is nowhere near as good as that model 1377 I had.
@@thomasmoje5926 You might think about picking up a new 1377 sooner than later before all the remain stock is sold. Crosman will be out sourcing their guns to China so if you’d like a built in America version they will be limited to what’s currently on store shelves.
@@thomasmoje5926 I’m really big on made in USA and since that’s going away I try to get the next best thing. But with Crosman closing down their production in the U.S. I don’t see myself buying anymore Crosman guns as I can’t support those actions. A China made 1377 isn’t going to have the same nostalgic value to me years down the road.
Am I seeing that yours is missing some screws on the pump handle part? I see one on the left and maybe it's missing one on the left and maybe missing the two on the right? Are those just decorative screws? I am trying to maintain an old one I just inherited.
I’m pretty certain it uses roll pins on the pump handle. I believe they changed to screws on the newer models but I don’t know when they made that change?
I noticed with yours, just like mine the bolt flys opens when you fire the gun. I'm just wondering if I'm losing some of the compression through this bad design 😢.
I bet we are losing some compression with that loading door/bolt popping open a bit. I’ve not looked into what can be done to try and lock it into place more securely. I don’t tend to shooting this 1377 very much so I’ve just lived with it.
Can you show me what the pivot arm roll pen is? I have one of these I would like to give a tune up to and no how to tighten what needs to be tightened and oil what needs to be oiled. Can you make a simple maintenance video? And does it only hold one pellet or one BB at a time?
@@airgunsofalaska I drilled a hole in a piece of wood 1 inch deep and placed the spring in the hole and compressed it only about 1/16 or so. I swear it worked.
Got the same one ran it till the barrel rifling is worn just shooting pellets it fell apart so I put a new valve and cup in it and its just like new, the power that is bought the new version recently happy with both
I guessed must have shot over twenty thousand or more pellet only through that barrel since 1988 built sholder stocks for it used scopes diesel pellets in it it took a lot of wear but it's still just for the garage to plink in now on rainy or snowy days
@@airgunsofalaskaI used engine stop leak in it for years that's why seals lasted so long a friend of mine borrowed it for a year or so tohe shot a lot of mice with it he said
@@Sawlon I don’t remember when they made a change but mine has a magnetic tip to hold the BB to prevent it from rolling down the barrel. I suspect the ‘85 version has it as well?
@@airgunsofalaska Yeah, the guy that I traded the guitar book for said it shot both. Was just googling and they said if it has a rifled barrel not to. Maybe this is just for the newer models. I just don't want to ruin something. Thanks so much for getting back to me!
@@Sawlon mine has a rifled barrel and is set up from the factory to shoot either pellets or BB’s. Quite a few .177 cal airguns to this day allow for BB’s or pellets through rifled steel barrels. BB’s are pretty inaccurate so I only shoot pellets now but I don’t see you doing any harm if you shoot BB’s. Just watch out for ricochets!
@@airgunsofalaska Even if you put lock tight (I have tried) it won´t help. Crosman should make two holes on the grips. One is not enough for such large grip area.
@@morriszachrisson8359 two screw holes per grip would definitely be better. I noticed the stock on my Drifter wiggled around while pumping as it kind of clicks into place and has a spring loaded push tab that holds it at the top of the grip. I replaced the original stock with an older Crosman model that used the grip screws. Now my stock is much more solid.
I have this same variant and its a Nov 85 edition. Ive been researching to upgrade the breech to a steel one but the cost is quite high. I was informed that I'd have to change my barrel as well. I found a first variant steel breech and barrel but i believe it wont work on the second variant. Even switch to the plastic newer style breech requies a barrel change also. So im stuck on replacing my variant 2 breech. Id even be happy with an original variant #2 breech. Any ideas where i could find one?
From what I’ve read in the past, it’s not really cost effective to modify this model to a steel breech since you also have to change out the cocking mechanism. Seems like the common thought is it’s just easier to buy a current model and install a steel breech on it. I installed a Crosman steel breech on my 2289 Drifter and used the stock barrel. These guns are unique with their loading port and cocking mechanism and worth more money in original condition. I’d leave it stock and enjoy it for what it is and buy either a new or used modern version and modify it. Something to be aware of, the steel breech isn’t perfect. Pellets tend to snag on the breech screw. The original plastic breech actually feeds more smoothly. Also, if your ‘85 shoots BB’s as well you’d lose that option as I don’t believe the steel breech comes with a magnetic tip on the probe. Someone likely makes something but again additional money for the conversion. I don’t believe the modern 1377’s shoot BB’s anymore.
The steel or plastic breech can be used with them and still have the cocking pinball knob. My buddy did his like that. He just had to use his old brass magnet bolt and put a lever in it to ensure his seal. But he definitely had to change barrels. He just made it a 22 caliber and put a 14 inch barrel and a suppressor on it as well. I'd just like to find the same breech it came with due to this old one being damaged slightly by previous owners..
13XX everyone should own a few. Great video!
??? Why the hell would you need 'a few'? You've only got two hands....?
