For the 48 holster, it is actually a 43x with a half inch EVO comp. Here is email with your team: Good Morning Jaime, That should fit inside a holster built for the Glock 48. When ordering the FO3 Light Mounted holster please select the Glock 48 with the Surefire XSC. However, please also make an order note at checkout indicating you have the 43X with the comp installed. We can attach the photos provided to your order in production. For the Staccato holster, it is a threaded barrel C2 with a Dawson Precision ICE Comp. Here is the email: We can certainly do a pass-through option for you. Basically, we would cut the holster to the size of the C2 and then we can use a 4.15” STACCATO P for the molding. This will leave it with a completely open bottom for the comp. We would use our C2 for the final fit check. If that option works for you, we simply ask that you make an order note at checkout that indicates the model comp you have and that you need the holster built using the STACCATO P for the pass through. Correct, the only portion sticking out the bottom would be the comp. The holster will be built to the size of the STACCATO C2 and that would include the front sight being on the inside as well.
