The No-Show Inside the Pocket Holster by Allen is ambidextrous and fits inside most pants pockets for concealed carry. This holster doesn’t add too much bulk, so the pocket imprint is relatively small and appears more like a wallet’s profile. With a smooth lining for an easy draw, the holster also features a suede-like textured gripping band that keeps the holster positioned inside the pocket when you draw your firearm. Right- or left-hand. Size 01 fits most sub-compact 9mms, & .380/.40 semi-autos Size 02 fits most .380 semi-autos Size 04 fits 3-4"" medium autos or small frame revolvers with 2"" barrel or less
