If you've ever shot an SSP pistol you can hear a definite crack in the report. That's the sound of the air flowing through the valve breaking the sound barrier. Nothing else in the gun is moving that fast. The solution is probably in the porting.
I use a Mantis sytem with severl of my airguns. There are adaptors available to fit the unit onto several guns but I have 3D printed short 'clip on' rails for my FWB Pistol. I had some problems getting the system to detect the trigger release on some of my airguns (its primarily designed for firearms) BUT.......... there is a trouble shooting routine where the unit detects the 'sound' of the trigger release and the Mantis guys can produce a 'custom' software fix for your gun. They were very helpful and had the unit detecting my FWB Pistol perfectly within a couple of days. With my Daystate Wolverine and Red Wolf rifles, the unit fits on a short rail fitted to the scope tube and works very well. With a silencer fitted, these guns are very, very quiet (they already have shrouds which take out the 'crack') so could be used indoors without too much of a problem. My FWB pistol and Anschutz 9015 rifle are essentially 10m guns and have a true 'dry fire' setting where the only thing that happens is that the trigger mechanism cycles as usual. For 10m shooters this is an essential training routine and guns are designed to tolerate this so there are no worries re damaging the gun. If you are looking to practise/improve aiming, trigger control and follow through then the Mantis system is a very good choice and, if you use true dry-fire (no air release), then essentially 'free' once you own the system.

Good morning GTA! Happy Sunday! I got up at 0500 and I’m on my second cup o’Joe. We’ve missed Sunday school so much and the class we were doing is probably nearly over. So, we’re going to head into Church just before 1000 hrs. We had a great Barn Meeting last night, a lot of great food and fellowship. This afternoon we have small group, I’ll probably get a nap in before that.
I have a thread in the gamo section of the spanish air gun gate. When you post your numbes on your rifle, post them there. That will make it easy for others to research this rifle. I do not have a chronograph and can not do that myself.
Thanks. I came up with this design about 10 years ago, my dad bought himself a model 25 that he was having trouble loading and I made him the 1st version of this design back then.

Have had great results at long range with .177 and slugs speeds in the 750 - 850 fps range, wind and time to target are the main enemies of accuracy then.
