I have this older American Classic 1377 and the pump pin is different than all others I have seen. I do not know if it is an original or how to remove it if I ever need to. The Gun which I bought in the box looks like new IMO. Both ends of the pump pin look the same.
Please let me know any info on pins like the one in my pic.
Thanks, Dan

Looks like the pin on an old 760 multi pump I have. Drive the small pin out and then you can get to the normal roll pin underneath.

I was going to say, the 760 variant 4 (1/77) I was just given has a pivot pin just like that. I have a set of 9 roll pin punches to deal with them though. Got them at Home Depot for 13 bucks.

I figured that is how it would come off. The pistol I have is still working great so I will just wait to if I ever need to. I was curious if it was Crosman or after market, even though it doesn't look like it has ever been worked on. I have a whole bunch of older Crosman pumpers and this is the only one with that type of pin.

Yep it looks like the same pin style! Thanks

Those darn roll pins are in there so tight, it'll surprise you. And make sure the punch is as close to the same diameter as the roll pin as possible. Or you're going to find it hard going to get it out! They're in there pretty tight. Too tight, I think. So I'm goping to polish it down a bit, reblue it, then see how easily it taps back in.

Just wait until you run across one of the pins with a tapered end, and the nasty little snap ring .

I have dealt with those and didn't think it was too bad! ???

I asked partly due to the pic on the box doesn't show the same pin type.
What year do you think this one is from? I think it is pre 80's
It has a steel breech, steel rear sight, wrap around grips.
I have read the first variant was 1977-1981. When did they go to the plastic rear sight?

How did you get the ring off, without marring the gun??

I have a pretty large variety of snap ring tools and one of them worked, that's all I really remember.

Then you probably didn't have a factory ring. The original didn't have anything to grab on to, and hardly any gap, at the split. Maybe 10 thousandths.

I had a brain trauma two years ago and it still affects my memory. Now that you described it I do remember it was troublesome and I did scratch the tube, I replaced it with a normal E clip when I put the gun back together.

I just happened across a 1322 with one of those split pins, and is why I haven't taken it apart to fix it... I have some ideas, we'll see if they work...

Look for the serial number on your pistol. All Crosman's built after July 1975 have the build date as the 1st 3-4 numbers.

Old proverb : if it works, don't fix it (or something like this ;))
However, just for your info, I tried this option from a stock one : http://www.gmaccustomparts.com/Stainless-Steel-Pivot-Pin (http://www.gmaccustomparts.com/Stainless-Steel-Pivot-Pin)
Though as not so easy as I expected, I could finally set it in, and it's been working OK for a few years now. But it was only the accessory to a very usefull threaded barrel band (IMHO)...(http://www.gmaccustomparts.com/13xx-Barrel-Band-for-silencer (http://www.gmaccustomparts.com/13xx-Barrel-Band-for-silencer))
So that's the way it looks now (see pic attached).
Some don't mind a bit of noise, some enjoy being really quiet. I belong to the second category. 8)

I agree but sometimes it is a question of improving it.
Here in the States a "suppressor" has to have it's own license, which is expensive and hard to get. There are exemptions for those that could never be used on a firearm though. But it is a bit dicey to get into though.
I have about 5 different types of custom aftermarket pins on various 13xx's that I have customized.

Oops :o. Sorry, I could have read your signature before touching my keyboard. We're not playing in the same category. Thought this could help but you're a few thousand miles ahead grom me... :-X

Those ones cant be pulled out the side like eclips. Take a small flat head and slide under then twist which will pop them off, it gets easier after a few times.

It did have the factory ring that is almost a complete closed circle!
