Have shot a few rounds through my Shadow 2 , just passed 1200 rounds actually, no--nada--zero malfunctions of any kind.
115 RN, 115 HP, 124 Hp.
the weapon has smoothed out quite nicely.
I recently shot 200 rounds of 115 grain plated RN from 7 yards to 25 yards ( about an equal number 27-28 at 7-10-12-15-18-21-25 yards) and ended up with a grouping of about 7- 8 inches (everything in the 9-10 ring) , thats standing unsupported.
I am not a competition shooter by any means.
IT has turned out to be a very accurate weapon and I imagine that it will get better.
I will say that my EAA (Tanfoglio) Elite Match is just as accurate and reliable and cost about half of what the Shadow 2 did, so its likely the best buy.
