Um ehrlich zu sein, habe ich das Kit von Herrn Schlottmann erst in Nachhinein kennengelernt, als ich über Google nach Problemen mit diesem Umbausatz gesucht habe. Damals kannte ich nur das Angebot von SWS.
Und wieviel Geld ich für welche Teile bereit bin auszugeben, sollte hier denke ich einmal keinerlei Rolle spielen... Das ist nämlich ebenso meine Privatsache, wie die Frage über die Herkunft dieses Geldes.... 
Zudem wäre dieses Kit mit Spannhebelbearbeitung auch sonst keine Option für mich gewesen. Nennt mich altmodisch, aber das Herumfeilen an Original-Teilen (wie auch immer das vonstatten geht) war noch nie mein Ding.
Und was das ominöse Thema "FAC-Power" anbelangt, lassse ich einfach einmal das Statement des Erbauers hier stehen:
"Our tuning kit is available in two options, sub 12 ftlbs and high power.
In .177 calibre particularly, the 97 isn't capable of energy figures much
over 12 ftlbs in it's standard factory format, (by this I mean with its
stroke remaining unchanged.) so even the high power kit will only return
very moderate figures 13-13.5 ftlbs on average. I am assuming, that the
factory rifle has the same action stroke as the uk rifle, which has always
been the case in the past.
We also offer a V-Glide kit, in 3 power options.
A V-Glide kit is a replacement piston, compression chambers of our own
design, along with the additional components that make up a full tuning kit.
option 1 sub 12 ftlbs
option 2 moderate power,( standard stroke,) Option 3 high power,( increased
stroke.)
The increased stroke equates to 8mm extra cocking length, this obtains as
much capacity from the rifle as is possible.
This also means that the rifle needs to accommodate the extra stroke, and
some alteration is needed to the stock inlet to allow the lever to travel
this greater distance, and also to the lever itself.
Both modifications are straightforward to do, and we can supply details on
how to achieve this.
The long stroke version can generate 15+ ftlbs in .177 cal and 18 in .22.
V-Glide kits are available on an exchange basis for your old internals or
non exchange basis.
The long stoke versions cost £175 non exchange, £150 exchange.
In all cases, as a target/completion rifle, the sub 12 ftlbs version is the
easiest to use, with minimal recoil and fast lok-times, though the long
stroke high power version shoots very well also.
It would be the best result, if high and low power is required, to utilise
the long stroke V-Glide kit, and have a second spring and guide arrangement
to switch to for low power, that should work well."
