Will the Gas Cap affect cycling or reliability?
It does not interfere with normal cycling or reliability when installed correctly, and adds a negligible amount of weight. It can be fired indefinitely in its down (functional) position or in its up position (no benefit) without impacting the original operating mechanics of your pistol.

Is the Gas Cap compatible with “Clone” firearms or other aftermarket slides?
The Gas Cap comes in models specifically designed around the different Glock generations OEM slides and fits factory-spec components, but we cannot guarantee fitment with the numerous aftermarket parts & pistols available.
