I`d like bay one of this pistols:
Hammerli AP40, Steyr LP10-P -silver, Walther LP300, Feinwerkbau P40
My subjective considerations are as follows:
The Haemmerli AP 40 is seldom seen. Drawback is the plastics grip-frame. An lightweight-option for those desiring less weight.
LP10 (Anschütz @), a proven performer. Hardly any negative feedback has reached my eares. (Well, some slightly harsch triggers, occasionally)
Walther LP300. Oldes of the ones listed. Hardly popular anymore. Trigger-issues reported repeatedly. I do not reccomend this one.
FWB P40. Abolutely recoilless. No other AP is absolutely recoilless as this one. Drawback: probably the heaviest newer AP around. Large grip, huge pistol.
Do not forget the better Pardini APs, and the proven Morini 162 series. And the new Tesro, which incorporates 200 bar and 300 bar cylinderfilling adapters (as the Walther 300).
And that is about it. You live in an area which was "looking eastward" not so many years ago. I note that you do not mention any of the APs made in the " formerly east-oriented countries".
The Tesro is made in the Tsjekkia, and assembled in Germany, and marketed by a Germany-based company, I think. To keep cost low (and reduce consumer sceptisism?).
Experiences with the relatively new Tesro AP are limited. But it is worthwhile considering this AP too, I think.
