Comparing Every 9mm Federal Premium HST! Which One Is BEST?
This review compares four Federal Premium HST 9mm ammunition types: 124gr, 124gr +P, 147gr, and 150gr Micro. Tested in a Glock 43 with ballistics gel and a clothing barrier, the 150gr Micro showed excellent expansion for short-barreled pistols, while the 124gr over-penetrated. The 150gr Micro was recommended for sub-compacts.
