I spent a little while fettling the trigger as shown in other threads- quite straightforward and effective.

Next I chrono'd it. Oh dear!

It was either very ott or ok- but very inconsistent. I started off by reducing the preload on the hammer spring. This didn't help too much, reduced the power but the inconsistency was terrible, 5.4 to 6.9 ft.lbs from one pellet to the next and so on!

Anyway- long story short, I gave the pistol a long coat of looking at The rotating breech block has an allen headed grub screw in the top, turns out this is an adjuster for the transfer port (a throttle if you will) Out of the box this is set flush with the top of the breech, looks neat but is totally non functional. If you swing out the breech block and start screwing in the adjuster it will take at least 4 turns until you can see it in the transfer port. At this point it starts to work.

After checking and adjusting I can now set the power wherever I want (legal of course!) but what is better it is now amazingly consistent, 3-4 fps between shots. I'm no expert, but does the regulator need a bit of back pressure to work properly?

Hope this helps anyone having the same problems!

thanks for the tip mine was same , if i screw the hamer screw flush, so it produces 12 ftlbs can i reduce the power to 6 ftlbs by just screwing in the breech block screw.

You may- but cocking will be difficult and so will trigger pull. I've left that adjustment pretty much as it was out of the box.

thanks ill do the same. by the way how many shots are you geting with the breech block screw srcewed in. ive screwed mine in about three quaters way in.

[Tony.T]

To be honest I've focused more on getting the pistol to shoot how I want it so I haven't bothered counting shots. My gut feeling is it's pretty good, but to me that's not too important. I would rather have 40 consistent shots than 60 inconsistent shots!

To anyone reading this and thinking this pistol is poor then trust me- it isn't. It's probably the most accurate and nice to shoot full power pistol I have owned (and I've had and moved on a few!)

I went out and bought one yesterday and had a go at setting it up today.

I can't see the link about trigger fettling?, can someone repost it please?

I did set the trigger to it's lightest adjustment which improved things, and I turned the power down to around 4 as I seem to be having trouble zeroing it with the red dot sight I got with it. It's probably me though, I know how to zero things, but the groups are just way to big, but as I'm not used to pistols it's frustrating seeing other peoples groups and them saying how accurate it is.

I tried resting it on my arm and got better results, but resting either the cylinder or fore grip on the back of a soft chair was rubbish, it looked like it was not moving, but the groups would suggest it was kicking up, but you could not see it?

Does anyone have any tips for an effective rest for zeroing, I get it that I will never be able to do it accurately freehand.

Thanks
