You should always first ensure that you are using the recommended weight of BBs and the correct gas for the temperature you are using the pistol at. We also recommend trying different hopup settings when measuring, as this affects the power output.

You should also check that the chronograph you are using for measuring the power is set up correctly and has the appropriate BB weight set.

Whenever you notice the power dropping, clean the inner barrel and hopup bucking, as there might be dirt or lubricant inside.

This usually only happens when the hopup is not adjusted properly. To adjust it, turn the hopup wheel which sits in front of the rear slide. You can find a video below about adjusting the hopup.

If the gun still does not hop properly; please first thoroughly clean the barrel assembly, or check if any parts of the hopup assembly are damaged or missing.

If your gas magazine is leaking after filling it, you first need to find out where it is leaking from. You can do this by filling the magazine with gas and submerging it underwater. The bubbles escaping the magazine will show where the leak is.

Leaking from the fill valve or exhaust valve:

If the magazine is leaking from either one of the valves, you should first try tightening it, though not too hard, as the valve might break. If the leak continues, then the valve most likely needs to be exchanged.

Leaking from gap in baseplate:

If it is leaking from the gap between the body of the magazine and the baseplate, then the hex screw at the bottom of the baseplate simply needs to be tightened. This screw should also not be tightened too hard, to avoid breaking it.

If this does not help, one of the seals may have dried out, in which case we recommend maintaining the magazine. You can find a video about this below:

If the gun is not cycling all the way, failing to reset the hammer or pick up BBs out of the magazine, then this is considered a cycling issue.

Causes for this can be too weak gas for a given temperature (e.g. green gas at 10 °C/50 °F), too low temperatures (< 5 °C/41 °F), or cooldown. Cooldown occurs if the magazine gets too cold from filling it often or shooting many shots from one magazine in quick succession.

Cycling issues will also occur when the magazine is running out of gas, as it cannot produce enough pressure with the remaining gas.

If this happens despite using the correct gas, there might be an issue with the hammer unit in the receiver or the blowback unit in the slide. Please check if there is any visible damage on the nozzle, piston head or hammer unit. If you can find something, please reach out to us with pictures of the damaged parts.

The thread protector on the TP22 outer barrel is made from polymer, which makes it lightweight but also bendy. Grabbing the thread protector near the middle will cause the threads to bind up with the outer barrel threads, making it difficult to remove.

We recommend only grabbing it at the very front or using pliers on the flat edges to unscrew it by turning the thread protector clockwise.

As the TP22 has a fixed outer barrel which is locked to the frame, over time with enough usage, it may develop a bit of play through wear, which causes the barrel to wobble around.

The TP22 is equipped with a barrel tensioning screw, which mitigates this issue.
To tension the barrel further, simply unscrew the screw marked in the picture slightly and test how much play it has:

Please be careful not to unscrew the screw too much, as the slide will not fit onto the frame.
