So, I recently purchased a glock tactical light for my G22, the guy threw in a magazine and is suppose to give me a glock holster for it as well. The light works great, it's bright, in great condition, and was a good price. The magazine however, was used in a g23, it's too short to function properly. My question is, and keep in mind i'm still pretty new to this, would a mag extension make the magazine longer to where it could fit? or would I possibly be able to trade the thing for a clip that would fit my glock at a gun shop?
