Does anyone know if the LaserMax LMS 1131 Guide Rod Laser will work on the Glock 24 Gen4? I bought this off of eBay and it says for Glock 19 and Glock 23 however it doesn't indicate whether or not it will work with Gen4. The problem I'm having is that it appears to be missing the Captive Spring Bushing which the seller says there wasn't one. The spring seems to large for the laser as it extends well past the Lasers Lens and in pics I've noticed that it should be the same length as the Laser. I don't know if there is a bushing missing or not. Any information anyone can provide would be greatly appreciated.
