In 9mm Sig 226 or CZ85. Both mine have shot about 1 1/2 at 25 YARDS off rest 5 shots.
ANY good 357 revolver, 686, GP, Python can outshoot it's handler IMHO. Not true for some 9mms. I had a Python that was freakin accurate but they are known to be a bit fragile. Shoulda kept it though looking at recent prices...GP-100 is probably the best for a hard use gun.
