This is a set of four items: a new Safariland replica 6354DO-832 optic tactical holster (compatible with x300/x300u), a replica belt loop adapter, a replica quick-locking system kit, and a leg band. Compatible models are Glock 17, Glock 18c, Glock 19, and Glock 22. Glock 17, Glock 18, and Glock 22 can be used as standalone units (verified with Tokyo Marui G17 gen3, gen4, and gen5). Glock 19 (verified with Tokyo Marui G19 gen3) can be used with a Surefire X300U (replica) attached. M&P9 and SFP9 can also be used with a Surefire X300U (replica) attached (see image 9). RMR compatible. *Because it has a locking mechanism, press the lock release button down to draw the weapon. Please be aware of this, as some people complain that they can't draw the weapon without knowing how to do so. The package may have dents from shipping. There are various manufacturers of replica x300 and x300u lights. I cannot guarantee compatibility with all replica lights. This is a replica holster, so please refrain from purchasing if you are seeking a perfect product. Thank you for a smooth transaction.
