Lets start with the ergonomics.
We begin the customization by removing finger grooves we then add a high under cut to the grip and finish with stipple job.

We then move onto the internals.

We do a full trigger job on the new internals. The combination of the trigger job to the Apex Trigger and Ghost Connecter gives you an excellent trigger pull.

These improvements give you a night and day feel to your Glock.
