My 452 arrived early this week, and I had time to get it to the range (indoor, 25 yard max) today. My oldest went along. We actually had a good day with 22's - she has a Henry, and I took along a Remington 552 as well. The CZ is stunningly accurate, even with open sights. The center red area of the target is about 2 inches in diameter, and the worst shot (we ran about 20 rounds through it) missed that by less than 1/2 inch (that was us - not the gun). The vast majority of the rounds hit in a group about an inch tall and 1/2 inch wide. I really wanted (and still do) the open sights, but I have to confess that a tip-off scope may be under consideration. All in all, very happy.
