1322 Upgrades Parts List

A scoped Crosman 1322 with a steel breech, and valve mod.

I am posting this because people have asked about my 1322 upgrades, and the air gun used in this video. This is the parts list minus my own modifications for the 1322 used to take pests and small game. See the update on my 1322, and where it is at today, below the parts list.

It has been over 4 years since this post was originally published. The 1322 is still an incredible air gun in its stock form, and even better with upgrades. I am still getting a lot of mileage out of mine. I’ve even improved performance by adding an 18 inch barrel, and a more rigid barrel band. For those that don’t do their own power mod to the stock cylinder valve, there are some really great, albeit a bit pricey aftermarket valves and pistons. The ALCHEMY AIRWERKS Flat Top HP valve and piston is a great option.

Buy an 18 inch barrel | Buy a barrel band

At 25 pumps my Crosman deeply penetrates 3/4″ pine boards at 7 yards, and is almost exiting. Its also incredibly accurate. I haven’t put it back on a chronograph, but I am positive it is pushing past 700 FPS, and maybe approaching the 800 FPS mark. It weighs in at 3 lbs. 6.8 ounces with a scope, and can still be carried in a backpack.

    Hi, great videos. I just bought the 1322 and was wondering is there a huge/minor difference between having the steel breech kit or 459MT mounts? Also your videos come out really clear so was wondering if this scope is better or worse than the one you reference: Simmons .22 Mag TruPlex Reticle Rimfire Riflescope with Ring, 3-9x32mm (Matte)? Finally in Option 2, you mention the RB27, do you need this in addition to the 459MT mounts? Thanks in advance. Keep posting those videos!

      Hi Taylor. The steel breech allows the gun parts to handle higher pressure and stress. Because of the steel breech I was able to continue modifying my pistol and have achieved over 12 foot lbs of energy.

      I am using the Simmons 8-Point Truplex Reticle Riflescope, 4x32mm (Matte) on the 1322 pistol that I listed in the parts for videos with the air pistol. Other videos on the website may have used the 22 Mag scope, but that’s because it is attached to a 22lr rifle. The videos end up being equal in quality and honestly has more to do with the phone camera and lighting.

      As far as Option 2 goes… if you use the stock breech that came with your gun, you will need both the intermounts and the scope rings, or you wont have an attachment point for the scope rings. Some smaller cheaper Tasco scopes may fit directly onto the intermounts, but most scopes over the 30 dollar mark will require scope rings with a 3/8″ dovetail to mount to attach to the intermounts. For 10 dollars worth of scope rings and almost fifteen for the the intermounts, depending on budget I’d say the steel breech is the better longterm investment if you plan on modding your 1322 for greater power.

      Hope that helps out a bit. Feel free to ask more questions if you have them.

    How do you get the wobble out of the pump arm on the 1322 air pistol besides putting in a $15 bolt and screws?

    • Benjamin David says:

      You can replace it with hardware store purchased screw and lock nut for a more snug fit. Personally, if it isn’t atrociously loose, it doesn’t bother me too much. I think it matters more for steadying for a shot, especially if not using a brace/stock mod.

    I’ll try this again. How do you steady the pump arm wobble on a Crosman 1322 pistol?

  4. Michael Ross says:

    I have an older model (sliding breech cover, toilet plunger bolt) 1377.

    Does anyone know, FOR A FACT, if it is possible to change the original finger-pinching forearm/pump handle for the more recent Crosman P1377BR-003 pump handle (hopefully more comfortable to use)?
    Do the pin holes of the original and newer pump handle line up?

    What drift pin size would I need to remove the two pins?

    Crosman could not answer these questions – maybe I first should have asked Frosty the Snowman.

      Hi Mike, I can’t speak to something I don’t know. Have you checked in the Reddit airgun forums? There are a lot of knowledgeable airgunners there, I’ll bet someone their will have an answer.

    What & where do we buy the parts if the pump fails to generate pressure already. What oil is suggested for the pump?
