Finally got to really test the little gun my wife gave me for Christmas. We both had major health problem and range time had a low priority I shot 70 rds of Speer GD and 50 rds of CorBon DPX. I had previously shot a box of ball ammo. When I got the gun, I did a very thorough "fluff & buff" and applied Molybdenum disulfide (MoS2) on the friction parts. The gun operated flawlessly !!! I even tried to "limp wrist", didn't bother it a bit. I was well pleased with the accuracy as well. I had installed 2 "Nighsiters" dots to get the "8" sight picture, it helps tremendously even in bright sun ! At 30 ft. my shots stayed in a 5" square. Question: I have a couple of boxes of Speer GD and CorBon DPX left. Which one would you use as SD ammo ?
