Massad Ayoob notes compact 9mm pistols like the Hellcat remain popular for concealed carry due to the capable cartridge, easy concealment, extra rounds and quicker reloads versus snub-nose revolvers. Smaller frames reduce control, but factory iron sights on the Springfield Armory Hellcat allow fast aiming without snags, and optics work better with appendix carry than pocket or ankle holsters. Ayoob says shooters should train with the micro gun they carry, as these pistols can prove surprisingly accurate.
