I noticed something funny. I practise with a very basic springer pistol (tempest). When I hold it like I hold my matchpistol Tau 7, it groups great at 5yrds. Ragged holes of 5 shots, sometimes as small as 1cm. Bút it doesnt recoil straight upwards but a bit sideways. (left).I put a tiny bit pressure on the grip with 2 middle fingers. Not with the thumb or little finger. I'm VERY familiar with springguns by the way, I shoot spring rifles at lot too.
When I grip it to let it recoil straight up, it doesnt group very well.(3cm at 5 yrds approx).
For the Tau 7 this grip works perfect as well. It can shoot ragged holes in 9/10 region like this.

Any ideas on this? Anyone similar experiences?

Just a thought, may this accuracy issue be related to the way you grip your pistol? For some silly reason it took me quite a few years to realize I was gripping my pistol in the wrong way, yet I had read a bunch of “How to Shoot” books and I had many discussions with better shots than I. I can keep the sights of my pistol so much steadier now that I’m gripping the pistol in the proper way. I put up a sketch for you to see:

Reading about gripping, even if at times information was conflicting, made me try many new things, and discover what works for me.
The hand is a changing entity, and you also have to take that into account.
In the end I came to realize that gripping is more of an art than a scientific method, and you will have to discover your way of doing things, and be open to new ideas that improve your scores.

It seems that, they grip I use works best with the Tau 7 (not necessarily with my order matchpistols though) and it groups best with the tempest too.
It just wondered me that it dóes recoil a bit sideways though, the tempest. Even grouping best this way.

I attribute recoil mainly to gun design and that includes the manufacturer grip. You probably have experienced that different guns recoil in different ways, but there are other factors to recoil.
Try to use some plastic putty "Sculpey" or similar on your gun grip, and study the consequences, it helped me. I use some masking tape over it because it needs to be baked to harden, and I don't think my guns will like that. The goal is to increase contact surface to an optimum, and in a way that help you shoot 10's.
Another hint I picked up along the way was that the middle part of your fingers, the little finger and the one next to it should be parallel to your target, but it might not work for you.
Once those two fingers are in position, you should apply pressure to the cheek of the thumb base, thumb and trigger finger should be able to move without any consequential movement, best studied under dry fire.
How hard you grip is another variable, I have used a Dynaflex to train and discover muscles I never new I had in my hand.
The angle of the grip is something to study in 3D, as you can see from the image above a grip is not a 90 degree type of geometry, there are angles to the back, angles to the side, since your harm starts to the side of your eyes nothing is in a real straight line.
Some people like to lock the elbow, others prefer tension.
Your feet are of extreme importance, and learning about consequences from changes on your stance is very important, that is where my grip starts.
...
The more you read and experiment the more you develop a sensibility to gripping, and the funny part is that your hand changes a lot from day to day.

Merry Christmas

Yeah, the tempest uses a very basic plastic grip. Its not even clóse to a matchgrip. I'm not gonna work on that though, cause they're kinda collectorsitems these days..I dó have wood grips lying around for them. But those too arent perfect ofcourse.
