Lawful Glock trigger upgrades: safe pull weights for carry
Every Glock trigger upgrade we sell is a lawful semi-automatic part, and every one of them can be fitted to a carry pistol. Whether it should be is a different question. This guide is our position on trigger weight for a pistol that leaves the house: what is safe, what keeps the factory safeties working, and what is better left on a range gun. It is the advice we give when someone calls to ask.
The factory pull, and why it is what it is
A stock Glock pulls about 5.5 pounds with the dot or unmarked connector and about 4.5 with the minus connector fitted to Gen 5 and competition models. Glock chose those weights for pistols carried by police and civilians under stress, with gloves on, in the cold, by people whose fine motor control has gone. A trigger heavy enough to need a deliberate press and light enough to shoot accurately is the balance, and 4.5 to 5.5 pounds is where the industry has settled for a striker pistol with no manual safety.
The floor: about 4.5 pounds
Our recommendation for a carry Glock is a pull no lighter than about 4.5 pounds, measured with a gauge. That is the minus connector on factory springs, or a good drop-in shoe on the same connector. It is where the pull is clean, the wall is clear and a startled finger still has to mean it. Below 4 pounds you have a match trigger, and a match trigger in a holster under a shirt is a different risk calculation. Some instructors and agencies set the floor higher; none set it lower.
What stays factory on a carry gun
- Firing pin safety and its spring: the drop safety in the slide. Polish the plunger; never lighten its spring.
- Trigger bar cruciform and the housing shelf: the second drop safety. Polish only; never file.
- Trigger safety tab: must block the trigger from the side. Any shoe that lets the trigger move without the tab pressed is out.
- Striker spring: factory weight, because the carry load's primer must fire the first time.
Upgrades that are fine on a carry gun
A minus connector. A flat or curved drop-in shoe with a functional safety tab. A 6 pound trigger spring, which lightens the pull by a fraction and is reversible. Polishing the connector face, the bar's tab and the plunger. A trigger with a set screw to shorten pre-travel, adjusted so the firing pin safety is not lifted at rest and checked as in the drop-in guide. Together these give a clean 4.5 pound pull that is still a carry trigger.
Upgrades to leave on the range gun
Reduced-power striker springs, which risk light strikes on the one round that matters. Connectors sold as 2 or 3 pound. Any combination that measures under 4 pounds. Lightened plunger springs, which are a drop hazard at any weight. Overtravel stops set so tight that a little debris stops the striker releasing. A range pistol can carry all of these and be a joy; a carry pistol should not.
What a light trigger can mean afterward
After a defensive shooting, everything about the pistol becomes evidence. A factory-weight trigger is unremarkable. A trigger measured at 2.5 pounds invites the argument that the shot was an accident or that the owner was reckless, whether or not that is true, and defending against it costs money and time. Prosecutors and plaintiffs' lawyers have made that argument in real cases. A minus connector at 4.5 pounds is a weight Glock itself ships; a match trigger is not. This is not a legal opinion, and a lawyer in your state can give you one; it is the reason instructors keep saying the same thing.
Measuring
Buy or borrow a trigger pull gauge and measure from the center of the trigger face, pulling straight back, five times, and average the readings. Measure again after 200 rounds, when new parts have settled. Write the number in the pistol's record with the parts fitted and the date. If you ever need to show what the trigger weighed, the record is worth having.
Duty and agency rules
Officers and security staff usually have a written policy on trigger weight and modifications, and it overrides anything here. Many agencies specify the dot or plus connector and bar aftermarket parts entirely; some require the NY1 module. A privately owned pistol carried off duty may fall under the same policy. Ask before you change anything on a pistol you carry for work, and keep the factory parts so it can go back to policy in minutes.
Gloves and cold
A trigger that feels right at the indoor range in September feels different in January with gloves on and numb fingers, which is one more reason the floor is where it is. If you carry through a real winter, test the pull in the gloves you wear; a 4.5 pound trigger through a thick glove is a good argument against going any lighter.
Training over tuning
Most of what a shooter wants from a lighter trigger is really a wish for a better trigger press, and that comes from dry practice. Ten minutes of dry fire three times a week with the factory trigger will do more for accuracy under stress than any part on this site, and it costs nothing. Tune the range gun as light as you like and practice the press on the carry gun as it is.
The carry setup we recommend
- Minus connector, or the Gen 5 factory connector.
- Factory or flat-faced shoe with a working safety tab.
- Factory striker spring, factory plunger spring, factory or 6 pound trigger spring.
- Polished contact points, nothing filed.
- Measured at about 4.5 pounds, tested with 100 rounds including the carry load, and recorded.
