Morphology

.45 + caliber

This phrase is compositional: 'caliber' means the diameter of a gun barrel or bullet, and '.45' is a numeric measurement, so a learner who understands numbers/decimals and the noun 'caliber' can infer it refers to a diameter of 0.45 (inches). The measurement + noun pattern is cross-linguistically common and follows ordinary English composition, making the meaning readily derivable for B1 learners.

Etymology

.45 Caliber names the bullet's size: .45 means 0.45 inches across, almost half an inch, and caliber refers to the 'width' of the bullet. That's why .45 caliber describes a gun or its ammunition with that larger bullet size.
