Is a 5" gun still better than a 4" gun in 2021?
This video from The Humble Marksman, featuring insights from a Master Class USPSA shooter, compares 4-inch and 5-inch barrel pistols in 2021, particularly for red dot optics. The testing methodology, dubbed 'bro science,' involved build drills and target arrays using Glock, Sig Sauer, and Walther platforms. Key findings suggest that for modern red dot equipped pistols, longer sight radius benefits are diminished, and factors like slide design, weight balance, and recoil management become more critical.
