Put 25 rounds through the full frame K-100 this week at a Prague range. Fits very nicely in the hand, low felt recoil (low bore axis), smooth DA trigger (I'm sure this specimen has been fired a lot so that may have contributed to this feature), and short reset trigger in SA that was just a pleasure to use.
The range instructor (required by Czech law to be present at your booth if one does not have a Czech firearms license) said it was a very good shooting, accurate pistol but it was very susceptible to fouling stoppages even after as few as 100-150 rounds with the rotating barrel. Again, that was one man's opinion and I am not sure how many specimens of the pistol he has worked with to form that opinion. Also, this is a Slovakian pistol and this was on a Czech range with potential for some national bias? ;-) Just saying, to be fair to the pistol.
Rental list (does not show Scorpion EVO 3 S1) -
Target on the left is from the Grand Power K-100 at 10 meters (the right hand target was shot from a well-worn 7.65mm Cz 83 and not all shots were aimed at center mass).
