Up to 1650 rounds through my 5” Full frame PDP. Gun has been 100% reliable and I have yet to had any issues with the optics plate loosening or zero changes with the Holosun 507c with the ACSS reticle. Trigger has definitely changed. The pretravel has increased in weight especially over the last 500 rounds. The trigger now has much more of a defined harder wall. Break itself from the wall feels about the same though. Still impossible to find 18 rounders anywhere. While I like the gun but it still has more shortcomings than positives compared to a Glock Gen 5 17 especially if you install a Timney trigger (only for range/game use).
