Dear friends, I once again experienced a failure to fire with my Ruger P-89. This time I did not pull the trigger a second time. I waited for a possible hang fire and then removed the round. The primer had a very slight dent in it and looked like it was struck much more lightly than the rounds that did fire. This has now happened twice in approximately 150 rounds. Both times have been on the first double action shot. All following SA shots have had no problems. I am now thinking it is a gun problem and not the ammo. I have made an effort to be sure the slide slams shut upon loading and I keep the gun clean and lubricated. I now suspect the problem could be due to a weak recoil spring and that the slide is not fully closing after I chamber a round. What do you think? Thank you, martin6
