Glock connector ramp angles

The design of the Glock trigger is so simple and ingenious it can be difficult to comprehend its operation. With the low parts count of the Glock every part is important, and the connector — which translates the rearward movement of the trigger (and thus, the trigger bar) to the striker assembly — is no exception.

Not only are there three different Glock connectors for different applications, there is a huge aftermarket in connectors as well. Glock connectors are typically interchangeable among weapons (there are some exceptions), while the aftermarket offers both drop in connectors and those that must be custom fitted to your weapon and preferences.

Although there are some wild connector designs out there, the main reason for changing connectors is to adopt a different angle for the ramp where the rounded nose of the trigger bar contacts the connector. Generally speaking, the steeper the ramp, the higher the effort required to pull the trigger fully to the rear, but the shorter the travel. Relaxing the ramp angle reduces the effort required to pull the trigger fully to the rear, but at the expense of longer travel.

In pulling the Glock trigger to the rear, there is often a take-up that brings the trigger bar into contact with the connector ramp. After that is what is called the wall, which is where there is increased effort to continue pulling the trigger to the rear. The steeper the ramp, the more prominent is the wall, while a super-relaxed angle on the connector ramp can virtually eliminate the wall entirely.

Depending on your preference, you might consider a Glock trigger with no wall to be mushy, or a trigger with a prominent wall to be difficult to actuate accurately. Typically, for self-defense purposes, you want enough wall to prevent a negligent discharge when your adrenaline is maxed out. Presumably, this is the reason why the NYPD specifies 8-pound or even 12-pound trigger pulls instead of the standard 5.5-pound pull in Gen3 Glocks typically sold to civilians. (Gen4 and Gen5 Glocks come with the dot connector, which is loosely rated at 5 pounds, and the competition models such as the Glock 34 and Glock 35 come with the minus connector, which is loosely rated at 4.5 pounds.)

Because of the trade-off of perceived effort versus travel, Glock owners are easily able to fine-tune the trigger action to their taste by swapping connectors, although Glocks carried by concealed-carry permit holders should retain the stock connector for legal reasons … you don’t want an opposing attorney grilling you on the stand about why you made your gun easier to shoot.

The angle of the Glock connect ramp does not directly equate to the weight of the trigger pull. However, I measured the angles of the connectors I have on hand and came up with this information, which I was unable to find anywhere else on the Internet.

Measured Glock connector ramp angles
Connector Angle Designation Notes
Ghost Edge 3.5 16° 3.5-pound Offset ramp to reduce take-up;
tab to reduce trigger overtravel
Glock minus 10° 4.5-pound Minus sign stamped on connector
Glock dot 5-pound Dot stamped on connector
Glock standard 5.5-pound No mark on connector

To measure these angles, I mounted each connector flat and photographed it as close as I could to the centerline of the lens to mitigate distortion. I then squared up each photo, aligning the stem of the connector with vertical. I imported each image into the Online Protractor, which I used to measure the angle of each ramp at 500x magnification. Here are the results:

Ghost Edge 3.5 connector angle: 16°
Ghost Edge 3.5 connector angle
Glock minus connector angle: 10°
Glock minus connector angle
Glock dot connector angle: 7°
Glock dot connector angle
Glock standard connector angle: 0°
Glock standard connector angle

Note that even though I measured off of the top of the connector, the trigger bar actually contacts the connector ramp on the underneath side of the lip.
