As the tittle say i got a 13xx from a buddy in a bag all in peaces lol...
So i said cool half the job is done for me now time to mod this and get it back up and running. 8)

So i flat toped the valve and piston, also did some porting to the valve and valve steam and also lightened the valve spring, i was quiet surprised the valve did not have a bleed hole :shock: , I polished the hammer and sear, lightened the trigger spring, cut the little notch off the trigger, and lightened up the trigger spring, and extended the bolt prob. :wink:

Its a cool fun little plinker now :D

here she is as she arrived :shock:
Image

some of the modded parts

all back together and ready for shooting fun. :D

Nicely done. Does that method of FTP-ing really work or will the epoxy fall out the pump cup eventually?

I too was gifted a 13xx. Mine was all in one piece though, a Christmas gift from my wife (she loves me, and actually listens to my airgun blathering lol). After opening all of our gifts and cleaning up the wrapping paper I was on my new I-pad mini (told you she loved me) ordering parts from S&A. She had bought me a 1377 American Classic and I immediately wanted to put a stock, steel breech, and longer 18" .177 barrel on it.
Once all the parts arrived and were installed I scoped it with a 3x9 CP scope and was suprised by how accurate it was but was less than impressed with the power. Couldn't even poke holes in a dog food tin. I wanted to paint the pump arm black to match the stock, so while it was apart I swapped the barrel and breech with the 10.1" .22 barrel as well as the transfer ports and plugged the bleed on the valve. Now she is packing a punch at 450fps at ten pumps. So far the novelty of pumping hasn't worn off and my 1322 is one of my top three favourites.
Question for you Ace. What is the benefit of cutting off the little tab on the trigger? I squashed the spring and now have a very light trigger but am always looking to improve. I am also interested in details of your FTP. Do you just fill the cup and file down the face of the valve? Do you have a procedure to fit it for tight tolerances? I have noticed that the FTP that you can purchase are adjustable.
Thanks Mike

Yeah, I'm not understanding filing off the travel limit on the trigger. Doesn't that just mean the safety falls out? Oooh, that might solve a problem I have with my new 1377 stock :shock:

so far so good I'll keep every one posted if it breaks, but it wont fall out because i put a little set screw in the middle of the cup so the JB weld has something to grab on to, just like i did on my 2289.

Awesome Mike you have a nice wife hope you got here something cool as well. :wink:
Cutting the little tab is just for comfort if you look at the first pic and the second you will see the trigger blade is not curved like a banana shape.
as for the FTP yes thats what i do it fits perfect tolerance is dead on. If you fill the cup just make sure you don't go over and onto the lip of the cup you need that part to stay nice and fixable to make a good seal. The FTP they sell is very nice you have the benefit of just changing out a simple o-ring, my method is just a home made simple yet effective way of achieving the FTP benefits.

No not the travel limit tab, as i said above to Mike its just the little tab at the top of the trigger blade and its just a comfort thing nothing really to do with performance. :wink:

Here are some pictures of the FTP i did on my 2289 so basically the same thing was done to the 1322.
I'm not saying or suggesting that everyone go out and do this mod especially if your not comfortable with this sort of thing, you must know what your doing especially when chopping the cone off the valve.

Make sure the set screw is siting below the cup lip.

Ah! Now that you pointed out the trigger difference in your pic I see it. If you get a chance can you post some numbers with your FTP? I am getting retained air at 12 pumps and enough for a weak second shot at 15-17. Would be cool to get two sub 500 fps off of ten. I am sure there would be more mods required to reach this goal but I wanted the 13xx to fiddle with after having so much fun with my 2240 (now a 1740 I guess?). I have a feeling both of these pistols will always be in a state of flux, I just can't leave them alone.
So you are taking the valve cone down to the shoulder and no more?

Not sure if that would be posible, the first shot would have to be over 500fps to get a second decent shot, for me its all about the less and easy pumping to get to 500fps. :wink:

Yes and no more.

Yeah kinda figured that was the case. Less pumps sounds good though. Thanks for the info Ace.

my 1377 holds air at 5 pumps and at ten it shoots one at 430ish and the second is 350ish. I'd be happy if I could get two shots at 400. guess I have to play with the valve spring to have two consistent shots..?

its a stock set up with bleed hole plugged.. all I did was change the hammer spring. the spring i used was too short so to take up the slack I put in a hard piece of rubber.

interesting I'm going to remove the valve and have another look at it i was a little surprised it didn't have the bleed hole on it so they must have done something ells to keep it under 500fps I'm thinking the volume within the valve or something. :?

For those of you that want to get 2 balanced shots with a single pump session, it can be done by lightening the hammer spring. To precisely do this instead of guessing how much hammer spring to cut, you will need a rear velocity adjuster to fine tune the hammer spring tension.



Ace, the new 1322s are not detuned like the old 2289s because they know it will not go over 500fps with the short barrel and being in .22 cal. You should be getting around 460 fps stock with 14.3gr pellets.

thanks T-H I'm getting 450fps with 16.20gr ran out of lighter .22 will have to chrony it again when i get some lighter pellets and see if the FTP made as much improvement as it did in the 2289.
