That bluing you get from heat treating would pretty awsome too, l think. Another possibity could be to bore the cylinder tube in a solid square  block of Aluminium and then shape the outside for grip.
 Just throwing random ideas. Pistols are great as is, but you know arm chair spectator and all that. 👍

If I had a big enough machine I could do more.

Blueing sounds good, but don't think alu responds to that.

I am coming up with a trigger frame made out of alu plate, or even a block including trigger frame that the air tube attaches too.

Ideas are great, it's surprising that although some seem ambitious, there are concepts and ideas to be taken from them.

Sweet pair! 
now... how about spring loaded bolt so you pull back and lock open to load it then a button releases the bolt forward ready to fire?? Wink

wouldn't that be hard on the probe?
 Noisier than just closing it? 
 Run the risk of wedging the pellet if it didn't sit straight.
 
 I know with the 1322 I like charged, then decocking the bolt slowly, pushing the pellet in with bolt, then leaving the bolt loose ( sitting in firing position, not locked but saftey on) which allows me to keep the hammer spring from sitting under tension as I wait or stalk.
 Extend probe (Pauly made) needs to be cocked to allow the pellet to fit, so no chance of pellet falling out if not cocked. Plus the probe pushes it in far enough it doesn't come loose. 
 Cocking is just pull back, push forward, turn downwards in one short, quick, hardly noticable finger movement.
 But that's just my view. Could be a good set up for all I know never having tried a button release bolt.

ouch... All that black definitely makes the cylinder noticable.
 Think those brown pistol grips toned it down a alot more.
 Still looks good. If it preforms as as well as it looks, that's easily gonna be a 30m bird gun.
 Whats the balance like with stock on?

Balance is good, although it's not heavy at all. Needs a higher cheek rest.

I like the idea of making a walnut forestock along the tank to give it a touch of height. I don't mind the black and metal, but a nice walnut is my preference. weather too bad here to go anywhere this week end.

I had a chance to shoot the pistol at 32m today. I had put the stock on and mounted a small rifle scope.

It really needs a cheek riser as my chin is all that touches as the scope is so high, but I gave it a go anyway.

It's actually great to use like this, and it was an enjoyable little shoot.

I put 2 targets out at 20 and 32 m. You can see the orange squares on the pellets in the photo. I was shooting off my raised knee sitting in my ute, out the window, so not a totally stable position. There was a brisk blustery wind coming at me, so you can see the pellets hitting slightly left.



The groups look kinda bad, but you can see a couple of good clusters there that happened once I settled in a bit. I am quite happy with this, as I know that with a proper shooting position and improved cheek support, that this is quite an accurate little gun, and 30 m is a huntable range.

After thinking about hunting pistols a lot lately, I feel that for hunting, having something with a bit of length is good, as I would tend to support it against something like sticks, or a tree rather than freehand, so this is easier to do with a longer pistol.

I just learnt where my jaw had to be on stock as that's what touches it on 1322.
I should imagine that it wouldn't be too hard to make a band that sits around the air cylinder with a square base to screw a bi pod into of you wanted (least with your tool access) Pauly. Probly be quite handy for laying in wait,popping birds from balconies etc.
What weight pellets were you using?
How big is the square on that target?

Using 18 grain jsb.
Squares about 25 mm. I had once tried heat forming some pvc pipe into a cheek piece that could be be adjusted up and down by tightening screws through top bar of stock.

Plenty on Web about DIY cheek raisers. Was looking into it couple days back for sig, which I don't get a cheek wield on either. Few good ideas on the nz hunting and shooting forum that popped up when doing a DIY search on the subject.

Couple more questions Pauly.
Whats behind the 20m target? I've noticed a couple of pellets haven't gone through paper.
Were you using strait out tin pellets as one of the ones that didn't go through has a lot of skirt damage that doesn't seem to correlate with how it sits in target.
Have you tested for best pellet or these just ones you were using as you had them.

It was just a piece of wood. Those two shots were actually the first 2 after a fill. If you remember, the speed can be a bit low after a fill until the pressure drops, then the hammer has enough energy to open the valve completely.

Or they have hit old pellets already embedded in that bit of wood, as i've used it before to put targets on.

If you look back through this thread I have groups at 15m that are shot with 18 grn. I have tried rws and 15 grn JSB and the 18 grn JSB seem the best and yeild the best power from the pistol. I don't sort my pellets, but check the skirts as I take them from the tin.

Pretty sure those groups can be tightened with a better shooting position.

Just re read through this thread...
I'm very keen to see how your current .25 cal build compares to these two previous ones, the progression as you are figuring out better designs and techniques.
If you can figure out a way to get a regulator, a mag and a manometer in there I think they would be awesome!

That shouldn't be too hard. The big thing is that as I am really amatuerish at it, what I make is quite bulky, and to keep a pistol a reasonable size, but still put in a reg, it will compromise tank size.

Also regs, gauges and mags easily add $200 + to the build.

Regs aren't alwaks needed if you can get a good valve hammer ballance.

With that build of mine, it did have a good amount of very usable shots if you look at the shot string. I actually think that getting the triggers better go a hell of a long way to making it accurate.
