Crosman had them on sale in 2019, I think, and I purchased 1. It is still in the box, never put a CO2 cart it in. I had been working on a 2401 project - 1701 barrel (same as 2300S) on top of a 2400 tube converted to PCP with Prod grip and trigger.It came out much better than I expected. Getting over 30 shots very consistent shots per fill. And arguably crosman’s best pistol trigger.
