Remove the Slop from your Glock

If you have not read my warnings and disclaimers about this procedure, PLEASE DO SO NOW!

The following procedure shows how to modify the factory Trigger Housing/Ejector in order to implement an adjustable stop. The stop can be adjusted to remove the "slop" and excess travel of the factory Glock trigger.

I must caution that this can be adjusted to the point that it will disable the trigger safety bar (that little dongle in the middle of your trigger). Over-adjusting this may also cause a situation where the trigger fails to reset and quite possibly slam-fire (dangerous). If you don't know what I'm talking about here, you are NOT qualified to do this procedure. Please stop now and exit this page!

GETTING STARTED

The following animation shows the basics of what needs to happen. Make sure you have all the necessary materials before you start. You may want to have an extra Trigger Housing/Ejector (about $5/ea) in case you screw it up, strip it, snap the tap off in it, etc

Please read the instructions below for more details.

You will need the following materials:  - A #50 or 0.070" drill bit  - A 2-56 tap (may not be necessary - see below)  - A 2-56 set screw, 1/4" to 3/8" long  - A drill press and vise (this can be hand drilled, but not recommended)  - An Allen wrench that fits the set screw

PROCEDURE

   Set up the part such that the front face (next to the ejector) can be drilled. The goal is to drill STRAIGHT down through the plastic until the bit is visible in the small channel where the trigger bar rides (see animation above).

   The hole can then be tapped, BUT, you you may wish to self-tap the set screw into the plastic. This makes for a tighter fit, and keeps the set screw in place once you've finished adjusting it. Plastic is soft, so this isn't too difficult, just be careful  not to strip your threads... keep pressure on the set screw as you drive it forward.

   Once the set screw is threaded all the way (visible and just barely protruding into the channel), you can begin adjusting it to remove the slop. I was able to take at least 1/4" of slop out of the travel.

FINAL NOTES

The procedure above takes out the excessive pre-travel, and a Ghost Rocket connector takes out the over-travel. As my model 22 now stands, there is about 1/8" of movement before a nice crisp break at about 2.5 pounds. This isn't quite where my P14-45 is, but pretty darned close, and definitely the best Glock trigger I've ever felt, bar none. This isn't a carry piece, nor is it used for home defense. It's a pin, plate and IPSC gun pure and simple.
