I have a Ruger P89 DC 9mm I need advice for.
I purchased this gun used many years ago. A few months ago I decided to start shooting it again. On the first session of 50 rounds I had some failures to fire with the first hammer strike. I disassembled the gun, cleaned out the sticky residue from dried WD-40, installed new firing pin spring, re-oiled lightly with CLP and reassembled it.
The gun has functioned fine on the next two sessions of 50 rounds each for a total of 100 rounds. Today I had a number of failures to fire on the first hammer strike when fired in double action. All of the rounds fired on the second hammer strike and all of the rounds I shoot in single action mode fired the first time.
I tested a magazine of 15 rounds all double action with one failure to fire. Since I am nursing a sore shoulder I then fired six rounds weak hand double action with one failure to fire.
The ammo is my reloads using CCI primers. My first thought was I failed to seat the primers all the way. However since the ammo is randomly boxed from a batch of 500 rounds I reloaded, the last 100 rounds fired fine and all of them fired fine in single action mode I discount this basic of reloading mistake.
I do not know if the hammer spring is factory original.
Please spare me the “use a softer primer” comments. I know CCI primers are hard which is why I like to test them in my SD/HD guns which I demand go bang everytime.
Suggestions?
