There are many options for carrying concealed, but few that provide as little bulk as the Versacarry.
Made completely of polymer, the Versacarry is more of a carry system rather than a holster, but it still provides a secure way to conceal a handgun on your person. Instead of wrapping around a gun, the Versacarry consists of a belt loop and a caliber-specific barrel stud, where the gun rides using a belt for retention.
The Versacarry is designed for inside-the-waistband carry only, and while it is not tuckable, it is very light and easily covered by a garment. It’s available in a variety of lengths and calibers from .380 to .45.
I like the extreme light weight and lack of bulk of the system, and that it works with any gun of similar caliber and barrel length. The only problems with the system are the lack of material between the gun and user, and that the gun cannot be “reholstered” without removing the entire system from the belt. As an undershirt will protect the user from chaffing during all-day carry and civilians almost never draw unless there is an incident requiring self-defense action, neither is a major deficiency.
Finally, the Versacarry is only $25, and if you don’t like the system, Versacarry will provide a full refund.
