Guys, I recently purchase a parkerized loaded model. I have fired about 110 rounds through it. Occassionally ( about 4 or 5 times so far) a round chambers, but when I squeeze the trigger the hammer doesn't drop it feels like the trigger wasn't reset. So I drop the magazine, eject the round reload and go back to firing. So I am looking for advice here -- what is happening? what am I doing wrong? My only previous experience with a pistol was fam firing the 1911 in boot camp 25 years ago, help!
