This is a single magazine pouch designed for bullets forward carry. It comes standard with adjustable tension and no attachment. The magazine pouch can be ordered with a Tek-Lok or a Safariland adjustable attachment.
When you specify carry side. I will assume that right handed is a right handed shooter and will make the pouches to mount on the left side with bullets forward. I will assume the opposite if you choose left handed.
There are two types of mag pouches available, open and closed front. Open front is designed for speed. These pouches hold the magazines with a bit less retention than the closed front. They are secure for USPSA, but not recommended for 3 gun. The close front are designed with a greater level of retention. These are designed for 3 gun shooters, or other shooters that want a very high level of retention.
The lead time on these mag pouches is currently 3 to 4 weeks from the date of purchase.
