Modern ones are significantly lighter weight, subject to muzzle rise (recoil makes point-of-aim move up) and just general jumping around. Very recent ones better address such movement, both in balance of action and by using significantly lighter (weaker) ammo designed for penetration over power (lots of tiny holes vs a few big ones). Addition of a silencer helps by mitigating muzzle blast & recoil. Old or new, it's having spent enough time shooting it to grow accustomed to the behavior; what seems overwhelming & uncontrollable at first becomes predictable & manageable.
