I will comment on some of the pistols I have owned or shot.
In order of accuracy:
1) Ruger 6" 357 Revolver (cant remember the model, probably made in the late 70's)
2) Nighthawk GRP
2) Fusion 5" (actually a tied for second with the Nighthawk)
4) Kimber Gold Combat
5) Colt Woodsman
6) FN 5-7 (only shot one mag)
7) SIG P220ST
8) Colt GI
9) USP 9mm
10) XDM 9mm
11) Automag (paintball gun
)
12) Taurus PT92 (this is the only gun in the list I would never own again)
13) Steyr M9 (with trigger work this would be much higher on list I think. I liked the gun)
Of course these are subjective results based on my skill and the quality of the individual piece I ended up with.
