The trigger spring in my PX4 .45 G range pistol broke @116,300 with only 14,700 rounds on it. It was the same as the prior. It kept on shooting, anyway. I noticed that the quality of the spring was not up to par.
@118,700 I replaced the slide rebound spring.
After shooting today (the usual 300 rounds) I found a terminal flaw. @119,600 rounds the slide was found to be cracked.
A long crack.
Through and through.
I no longer feel it would be safe to keep shooting it. In post 438 I mentioned that I had just gotten a back-up for my range pistol. Well, it is that time. My shooting will not slow down, nor will I get new range mags and equipment. I will simply have the stand-in stand in.
Terminal round count: 119,600
New range pistol round count 650.
