Full Size vs Compact vs Subcompact Pistols!
This video compares the ballistic performance of Federal HST 9mm ammunition fired from three different-sized handguns: a subcompact Glock 43 (3.5-inch barrel), a compact Sig Sauer P320 (4-inch barrel), and a full-size Glock 17 (4.5-inch barrel). The experiment aimed to quantify the difference in bullet penetration and expansion based on barrel length. While a slight increase in penetration was observed with longer barrels, the differences were minimal, suggesting barrel length has a limited impact on overall bullet performance in this specific test.
