Modded My New 1322 Right Out of the Box, Also Moly Paste in Pump Guns.

[markasaurus]

I paid $60 for this Crosman 1322 from Amazon (sorry about my foot in the picture DANG).  I just got it last week but did a lot of research before deciding to get a 1322.  I also considered the Browning 800 and a couple other spring air pistols - but i decided this pistol was the best choice for me (i already have two spring piston rifles, an old RWS 34 and a Beeman Grizzly).  I like how you can mod the Crosman however you want it and you will always be able to get parts!

I have put the super pumper pump grip from RBGrips on - fast service and a really nice wood piece.  I also changed the valve to a Mellonair one and the piston to the brass one from airgunsmith.com.  But not without breaking off a cheap hex wrench in the breech screw first!  I got it out by using a cheap mini screwdriver as a mini-chisel - dpes any body know a cheap source for the breech screw?  Nothing the hardware store has fits the hole!

Like i said i bought the piston via email and paypal from AGS and I posted a question to airgunsmith on whether it was a good idea to lube a pumper with moly paste.  And this is the interesting reply i got:

The molly is good for the piston but the valve needs to be lube as well.
when running molly we used enough to lube the piston, the valve dried out and corroded.
when we ran enough molly to lube the piston and the valve the valve got plugged.
when we ran enough molly to lube the piston then lubed the valve on the inside,
the moisture and pressure from pumping washed the molly away from the valve again it corroded.
For the Crosman 13xx airgun we now consider the airgun lube (oil) expendable,

The oil we provide with the piston was created for us by an oil and grease manufacturer, not some home brew concoction.
we were in contact with the manufacture told them what the oil was going to be used for and the problem with aluminum valves.
aluminum in contact with inexpensive steel  heat, cold and moisture generated from pumping .
They manufactured us a branded oil with corrosive inhibiters as well as being fully synthetic that was tested to be safe with the seals and O-rings
that airguns use we sent them the seals and O-rings from 30 different airgun both domestic and imported from all quality of airguns,  6 months later they sent us oil.

Molly is a good lube but is must be used with proper applications.

congrats and nice start!
welcome to the disease
the only place on my gun that got molly was the trigger group and pivot pin
i hear the horror stories of the aluminum valve i guess when i was using them the 30wt non detergent motor oil kept them from corroding
dont have to worry about the brass valves corroding thats why i have them in my pumpers now
airgunsmith does have a nice piston havent tried one yet but have seen the results of his work he also does a good valve job from the numbers i have seen

The mix of black hand grips and wood grain pump grip looks surprisingly cool to me.  Kind of a Doberman or Rottweiler vibe!

to answer your breech screw question, you might need to get one from Crosman unless you have a good screws and bolts store nearby.

the good news is that if you order it from Crosman, you can pick up a steel breech kit at the same time!

You'd have to buy 50 of them at McMaster-Carr.  Send me a US dollar bill and a pre-stamped (and self-addressed) envelope and I will send you two of them. Yes, 4-48 stainless steel slot head 1/4" length.

forgot to mention on most after market screws the head needs to be turned down

Just chuck up on a drill and spin the side of the screw on a file until you get the head diameter you need (I use a DMT progressive grit diamond stone set that I have for other purposes).  It only takes a few seconds.
