I picked up a 2240 at my local Walmart for $63 the other day. So far, it seems to be a pretty neat little pistol. I've been looking for something like it for a while as something to carry while out grouse or bunny hunting.

Trouble is, it seems that everyone and their dog has one and so there is a vast amount of posts and YouTube videos about it and I don't know where to begin. I hear the you can get them closer to 500fps from the factory 460fps but I really don't know what mods to trust. I certainly don't feel comfortable taking a dremel to the valve chamber.

Any suggestions on this or comments overall on the gun?

Thanks guys!

I have 2 and both were low 400's from factory. Added a 14" barrel and some tubing behind the hammer spring to get to 490(and a stock to shoot it as a rifle).
The other, a 10" barrel and nothing else got me up to 450. Which works great as a 10M pistol. No dremel necessary.
 
Lighter ammo will also give you a higher fps but be careful if you don't have a PAL as current laws now apply to not only what they box says but the actual speed of the pellet/BB that comes out of the airgun. Go over 500 and you have a firearm by law. Stupid I know but the RCMP freaked out when they tested some airguns with plastic type pellets and got more fps than what the company sai on the box. All Canadian airguns (at least by Crosman have different valves than in the US so that any attempt to pump them over 500 bleeds off.)

Airgunsource.com and dlairgun.com both have over 8 different brands of ammo with Gamo having PBA and some pretty cool unique ammo. I find D&L to be an easier to use website but they have to email you a shipping quote which sucks, I looked at a the new 1322 at Airgun Source and they gave me a reasonable price quote right on their website ($14 for the long Crossman 1322).

I have not used any non-Crosman ammo yet so I can not tell you which to use at this point.

BTW, it seems silly to have a single shot CO2 pistol but I'd still get one on the used market, I like the look and it reminds me of a ray guy lol. Still, I see going to the expense of CO2 as a way of getting multiple shots for handgun like action in your basement "range", the reason I want the 1322 is more for a survival non-CO2 compact "rifle" when it is combined with the Crossman stock. This is only theory as you can't hunt with airguns in Nova Scotia. A brake barrel spring rifle is ideal where length is not a concern...but I am rambling.
 
Yeah, there is a metric whackload of info out there for tuning and upgrading the 2240 Crosman.

Best is to read a bunch, then pick and choose the mods you do. You really do need to have a chrony handy to tune it to get near the legal limit without going over.

Realistically, as long as you do not do stupid things, you should not be in line to get it checked. Ie: don't be waving it around downtown, or shooting it where you are not allowed, etc. Not much worry of finding a super lightweight .22 cal pellet to get you in too much trouble, but you shou;ld be aware of this issue, too. The actual law was rewritten to avoid having to prosecute folks when the super lightweight crappy pellets started showing up on the store shelves. They wrote in that the pellet had to both exceed the 500fps AND have more than a certain amount of energy (4.2 Joules?). Anyways, it does not give you much leeway, and seems mostly to affect the .177 crowd. But be aware.

So...Take a look at the mod that relate to improving the gas flow through the transfer port, as well as the mods to the hammer spring and hammer to increase the gas flow a wee bit.
On spec, I am supposing that you are not really interested in putting a huge long barrel on it, which is the usual method to increase the velocity a bit (longer equals more time to push the pellet by the expanding gas).

Be aware that cold temperatures affect CO2 pressures a lot. You will either have to keep it warm, or have the ability to adjust the volume of CO2 that you get through the valve (usually by varying the hammers blow strength).
Or you can just live with it, and get out and enjoy.

Oh yeah. Practice practice practice! :)

Thanks for the info so far guys. keep it coming if anyone has anything else to add.

I'm not interested in putting a longer barrel on it as it'll likely be carried in a holster while hunting. It's long enough as it is. (and yes, it is perfectly legal in NB to hunt with an air pistol) I have added a small spacer behind the hammer spring but I doubt I'm up to ever 475 yet. I'll have to chrony it next time I'm out at the paintball field. I've also changed out the trigger spring for something a little lighter to improve the trigger pull weight. Both are rather simple mods I guess and I'll probably leave it as it is for now. I might re-shape the grip a bit to allow for a more comfortable had position and click-adjustable rear sight would be cool too if I can find one.

Overall, so far anyway, I'm not overly impressed with the gun, but we'll see how it goes as I continue to learn its ins and outs.

Thanks again guys!
 
I love mine...that .22 pellet packs quite a wollop for what it is. You really can't go wrong with a crosman single shot pistol...there is so much you can do with them...and the mods are very affordable
