Don't rule out the newer synthetic sealed, lighter pistoned, longer stroked HW35s. really nice sub 12 FP.
99 is fine
95 to my mind HAS to be short stroked - but that's just a TbT nose, and you end up around 3mm longer stroke than a 99, shich is nicer, and without needing to do you diy de-galling modifications. You also get to use the same barrels as the hw80/90 so far more options if you want to change lengths or calibres.
So my personal list in order of perference
Short stroked 95
HW35
HW99s
factory stroked 95
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
