Anyone chrono this stuff? It feels pretty hot. I shot over 200rds today. The JHP45 was whacking my thumb knuckle pretty hard. It was really snappy. Is it the gun? I just got this one. It is new to me and looked like it had very little use. My other JHP has 2000 or more through it. I shot most through the 4595. It is my first time out with one of these so I have nothing to compare it to.
