I picked up a 453 American used off CGN in Canada, and scoped it with a 4-12X40AO, and it is a laser guided missile launcher. The 453 has the set trigger, which I have yet to use because the normal trigger is so sweet - likely around 2 pounds with only a hint of creep and no overtravel. Lights out with bulk ammo, and I paid less than the cost of a new 452 for the 453 which typically runs 150 more.
