Installation Guide Perfect Fit PROComp for Glock

Thank you for your purchase of the Perfect Fit PROComp. With the correct installation of this product you will experience a very noticeable reduction in felt recoil and muzzle rise. This will enable you to quickly get back on target for quicker follow-up shots. It is recommended that you have this PROComp installed by a competent gunsmith.

These instructions pertain to the Glock GEN4 and GEN5 9mm pistols(models 17, 19, 26, 45, 47) Please read and understand all steps prior to continuing. We want you to enjoy the awesome benefits of owning and using Backup Tactical products

Step 1. Disassembly

Remove magazine, lock slide in reward position, check chamber to make sure weapon is unloaded, Pull slide take-down lever downward and remove slide towards front of pistol. (if you need help with this step, please stop what you are doing and find a gunsmith)

Step 2. Disassembly

Remove recoil spring assembly and barrel and set aside. Install new threaded barrel
(Hopefully you have purchased one of the fine barrels available from Backup Tactical Corp).

Step 3. Reassembly

With barrel extended out the front of slide, First remove the rubber o-ring from the end
of barrel then carefully thread on the Perfect Fit PROComp (this is right hand thread
1/2-28) Continue threading it on until it stops, then reverse direction only the amount
needed so that the comp is aligned properly with front of slide. Move the barrel
rearward into the slide and make sure it clicks into battery position. (There should beclearance between the Comp and front of the slide)

Step 4. Reassembly

Insert the slide and comp assembly into an adequate vise of some kind. (if you do not
follow this procedure your pistol will not operate properly and you will not be
happy) Make sure you are protecting the finish of your slide and comp by using soft
jaws in your vise or some sort of flat wood or plastic strips. The idea here is to make
sure that the comp and slide are in perfect alignment with each other before performin the next step.

Step 5. Reassembly

Remove set screws using a 5/64 allen wrench and apply fresh BLUE loc-tite, then
torque the set screws to a maximum of 12 inch lbs.

Note PLEASE NOTE As an alternate method you can install one set screw then use #29 drill bit in a drill motor, slightly dimple your barrel using the other threaded hole as a guide. Be careful to maintain the correct angle so as to not damage the threads in the comp with your drill bit. MAKE SURE TO ONLY DIMPLE A VERY LITTLE !!!! GOING TOO DEEP WILL DAMAGE YOUR BARREL AND MAKE IT UNUSABLE. The idea here is to just make a “SEAT” for the set screw that will prevent the comp from rotating during operation. Install one set screw in the hole that you just dimpled and repeat process in 2nd hole. IF YOU HAVE ANY QUESTIONS OR NEED TECHNICAL ADVICE, PLEASE CALL 757-724-5441 10AM-6PM WEDNESDAY THRU SATURDAY
