 The security 380 chamber and 380 ACP. This has a 3.42 inch barrel, a 15 and a 10 round mag. Three finger contact with that extension with the base plate. The security 380 has cocking ears. It just sticks out a little bit, charge the gun. It has cutouts in the slide that could also be used as forward serrations. The light rack, very light recoil spring marketed toward people with weaker hand, perhaps injured or just want to shoot a lighter shooting round like 380. Serrated black, adjustable rear sights and a green fiber optic front sight. Has a three slot pick rail right there. It's a hammer fired pistol right there and also has a thumb safety. This is meant to be holstered. It's not a micro 380 like the LCP Max.
