Things I liked: Accuracy is excellent. Rear sight is excellent. On balance, a very nice gun at this price point, and I would buy again.
Things I would have changed: Trigger, trigger, and trigger. As noted by many other reviewers, the trigger is gritty and creepy. It can, however, be adjusted down to a reasonably light pull to break the shot. Also as noted by others, the plastic grips are...plastic grips. Finally, the dovetail on the receiver is canted at a slight angle, which means the rear sight doesn't sit "square with the world." However, this is an aesthetic rather than functional consideration, since the sight adjusts to zero just fine.
What others should know: My review pretty much mirrors what I'd read prior to buying the 2300S, and I'm satisfied with the purchase. I'll polish up the trigger action and/or purchase an aftermarket two-stage sear and eventually buy some aftermarket grips. With those modifications, the 2300S will be a gun that certainly can exceed my capabilities and should last a long time. Overall, I'm pleased with the gun and recommend it.
