not sure if it's the only difference, but it's a great difference between the 452 and the 455. I found the stock on my 453 to be nicer than the 452 lux I looked at. Mine has the cheek weld pad. It feels like the centerfire rifle stock. Came with a decelerator pad installed, etc.
Is the single set trigger the only difference between the 452 and the 453?
