Things I liked:The Crosman 2300T both looks and feels like a well designed pistol. Both the trigger stop and trigger pull adjustments worked very well. Liked very much that the CO2 cartridge did not loose any gas when being installed. Things I would have changed:Painted the rear surface of the front sight white which made it easier for me to sight it in. Something other than plastic grips would have made this gun both feel and look more expensive. What others should know:Initially had a problem with the rear sight being positioned far to the right of the center line of the pistol. Apparently, this was caused by the barrel being installed in a slightly clock-wise direction to the center line of the pistol. After contacting Crosman customer service, I fixed the problem within a couple of minutes by loosening two set screws, rotating the barrel counter-clockwise, re-tightening the set screws and re-sighting the pistol.
