Just getting started modding my 1377 and am going to place an order with Crosman for a few things. I am compiling a list of things that I may need in the future of modding/repairing. I plan to do an extended barrel for use with shroud, new pump arm, and flat top valve/piston soon.
What bits and pieces should I get?
Get a longer barrel from them (only option for .177 is 24" that's longer than the stock 10", that's part # 1760SE-001 $19.07), might as well pick up a spare valve (PN 1322C013, was $6.08 in August), front sight PN 788-101 $1.54, shoulder stock PN 1399A001 $10.87, 760 front barrel band PN 760D008 $1.15, grips Left PN 1700-031 right 1700-032 $1.74 per side
I haven't bought a backpacker pump arm so I don't have that price or part number handy... That's the cheapest way to get parts, might as well make use of the $4 shipping :)
Throw in a few breech seals. Steel breech maybe a couple of extra valve stems and check valves.
Safety spring & ball!!! ;)
Awesome :-* adding to my list! I am going to also play around with a 22 conversion so I will throw the parts I need for that in.
The 2289G forearm part number is 1389-025. They were $8.75 ea last time I bought one.

That is a "must have", along with the extra safety spring and ball like Bill mentioned.
I am definitely going to the pump arm from the 2289. I am going to pair it with some grips from a 1701.i had me heart set on a nice set of wood furniture but the lack of availability is making me go the other way. It will leave more funds for other stuff too.
Thanks, need to get my order list in . . . order :D
So this is on my list so far:
Disco hammer spring 1761-009
1377 trigger spring 1377-080
2289 forearm 1389-025 8.75
black stock 1399a001 10.87
1701p grips 1700-031 and 1700-032 1.75
177 24" barrel 1760SE-001 19.07
Valve 1322C013 6.08
2289 22 14.5" barrel 2289-001
safety detent spring 1322-017
Safety Ball 105-039
rear frame screw 1322a029
breech seal 130-036
2289 barrel band 788b011
2289 barrel screw 781a012
not going to buy but for future reference....
1701 trigger conversion
Grip Frame 2220-103 35.08
Hammer CH2009A009 19.47
IMO, one thing you really need is a real good .050 allen wrench to remove that dam 4-48 breech screw. Then you need to PM me with your address and I will send you a SS slotted 4-48 breech screw. This is what we do on this forum, we help each other out. ;) ;)
I saw a 14.5" .22 barrel
that needs a .22 bolt...
I ordered seals and pump cups just in case...
the first thing I did though was to get solid pump pivot pins in my opinion a MUST...
I have the upgraded steel breech on my 1377.i couldn't find a part number for a 22 Cal bolt that would work with it. Anyone have it? I am probably goingto do an aftermarket one eventually. Same with the pump pin. After my Crosman order, I need to send some emails :)
Yep, 2261-002 is the discovery .22 bolt I believe and is $3.35
I saw that it was suggested but I don't see the steel breech kit on your list! Part #2240SBPK (for a .22 cal upgrade). I got mine back in May (2013) for ~$35. I've seen comments to the contrary but my steel breech kit was considered part of the total order (even tho it ships from a different location) and there was no additional shipping charge. I would get a couple of the 4-48 breech screws (even if MudDuck is kind enough to send you one of his). They're small enough to easily lose so if you lose the one he sends you, you'll be S.O.L. You won't find them at the local hardware store either.
I would consider deleting a couple of items from your list. The Crosman front and rear frame screws have a square drive and are a pain to get out without scratching the grip frame. I (like many others) have replaced mine with 8-32 button head machine screws. They look nicer and are easier to remove without scratching the grip frame. The safety detent ball is merely a 3/32" (0.093") ball bearing. You can get 3 of 4 of them at your local hardware store for the $1.15 that Crosman charges. With that in mind, I do appreciate the fixed shipping charge on Crosman orders and the reasonable prices on most of the air gun specific parts, so I don't always try to get the standard parts (screws, pins etc) from a local source. I do have a bit of a hard time paying 3x the cost for that safety detent ball tho. I'm sure that will generate a comment or 2 :( but that's the way I look at it. Flex
