I had always been under the impression the Glock 19 had a 5 lb trigger. Recently I threw a 3.5 connector in one and bought a Lyman trigger scale the digital one. The 3.5 gen 3 g19 averaged 6lbs 9 ounces. The oem stock gen 4 measured 9 lbs 7 ounces.
I averaged 3 pulls for both twice because the numbers were so high I thought I did something wrong initially. My 1911s are both set up at 3lbs 6 ounces for comparison. I'm pretty sure glocks would shoot better with a more traditional pull weight like 4.5 lbs. |

Normal. The actual pull is always more than the rating of the connector. I have no idea where they come up with those numbers. Probably some clever marketing guy realized people would think more highly of a gun if they thought a 5.5 lb trigger was standard or that a 3.5lb connector would yield a 3.5lb pull. That's what I always took the numbers to mean. |

Do you have a NY trigger?

http://www.m4carbine.net/archive/index.php/t-106458.html Guns Magazine, Nov, 2004 by Massad Ayoob The real story Glock trigger pull weights: Glock critics say its trigger pull is too light. It may be that they've been weighing it wrong My friend and fellow instructor Dave Maglio is a Glock fan. His department issues him something else to wear in uniform, but he almost always has a privately owned Glock for off-duty carry. When he became the 17th IDPA Four-Gun Master, he did it with a Glock 17 9mm in Stock Service Pistol and Enhanced Service Pistol class, and a .45 caliber Glock 21 in Custom Defense Pistol against the short trigger pull 1911 autos. "Hell," he said, "I would have used a Glock instead of a Ruger GP-100 for Stock Service Revolver if Glock made a wheel gun." One of Dave's pet peeves is people who complain that the Glock trigger pull is too light. It comes out of the box with a nominal five-pound pull. This upsets some folks who think of that in terms of double action revolvers and autos with pull weights in the 12- and 14-pound range. "People are missing the reality," says Dave. "Think in terms of human engineering. The Glock trigger-pull weights are apparently taken at the tip of the trigger. It's a pivoting trigger design, so the leverage is greater there, and the pull-weight seems less." He explains, "Look at how people actually shoot Glocks. Their index finger is on the middle of the trigger, where the safely lever is, not at the toe. The middle of the trigger is where we should be taking the measurement. It weighs out heavier there." I proposed an experiment. Dave broke out his Glock armorer's kit and a trigger-pull gauge, and I unloaded the Black Hills 165-grain EXP .40 S&W ammo from the Glock 22 I was carrying. He then installed every reasonable combination we could think of, and weighed the triggers with each at the toe, and again at the center of the trigger. Three Gets You Five Glock sells the 3.5-pound connector only with the 6-inch barreled longslide target pistols and in the Tactical/Practical series with 5.3-inch barrels. These are respectively the Glock 17L and 34 in 9mm Luger and the G24 and G35 in .40 S&W. There is a long history of Glock factory literature adamantly stating that these trigger pulls are for competition, not duty or defensive carry. Every American police department that I know of which has adopted the G34 or G35 for issue has fielded it with a heavier trigger pull. Measured at the toe of the trigger, the nominal 3.5-pound connector with standard trigger spring actually weighed three pounds, 3.7 ounces. Measured at the center of the trigger, however, it tripped at five pounds, 1.3 ounces. Some Glock aficionados think the trick set-up is the 3.5-pound connector with the New York Trigger (NY-1) module replacing the standard S-shaped trigger spring. This gives a firm resistance from the beginning of the pull. The real, often unrecognized benefit of the NY Trigger is a smooth, easy pull that is generally estimated at a bit over five pounds. In fact, it measured six pounds 0.5 ounces at the toe of the trigger, and eight pounds even at the center. This system is reportedly standard with a Midwestern state police department that issues Glocks. The Five-Pound Connection The five-pound connector mated with the standard trigger spring is what comes out of the box when a private citizen buys most models of Glocks. It is said to have an average pull of 5.5 pounds. In measuring this combo on my G22, Dave got four pounds, 1.5 ounces when the gauge was hooked to the toe of the trigger, and six pounds on the nose when he attached it to the center of the trigger. Then the threw in the NY-1 module, which is what I had in the gun to start with along with the nominally five-pound connector. It went six pounds, 1.1 ounces at the toe, seven pounds 1.5 ounces from the center. This combo is normally expected to bring pull weight up to eight pounds or so. However, I've shot this gnu a lot and worn it in well. With the NY-2, or New York Plus module in place, which is said to deliver a pull of close to 12 pounds, we got eight pounds 1.1 ounces at the toe and 10 pounds even measuring from the center of the trigger. Finally, with the so-called "Miami trigger"--an eight-pound connector and the standard spring--the pull measured six pounds six ounces at the toe and 10 pounds even at the center. The bottom line? As with all pistols, individual Glock pulls may weigh more or less than specified, or anywhere within the specified range. The pulls are indeed heavier at the center-where most of us actually put our finger-than at the tip. It was an interesting experiment, but I'll still keep the NY-1 module with five-pound connector in all the several Glocks I own for self-defense. |

I have found all mine to be very close or better then advertised. I own the same Lyman, my 3 pull average on my Stock Glock triggers is.
G-35 gen3/ 5.4 lbs G-22c gen3/ 5.1 lbs (this gun has been shot a lot) G-19 gen3/ 5.6 G-27 gen3/ 5.9 G-23 gen3/ 5.5 G-17 rtf2/ 5.2 G-22 gen3/ 5.9 G-17 gen4/ 4.15 G-19 gen4/ 4.12 I have another gen 4 19 that I haven't tested yet, but the finger tells me it's somewhere in the above range. How high on the trigger are you testing, I place mine on the lower third of the trigger were my finger pulls. The higher up the trigger the harder the pull. |

Maybe the ny is now standard? Both my guns are low round count and last 16 months of production. I have one oem gen 4 g19 at 9lbs 7 oz and one gen 3 with ghost 3.5 at 6lbs 4 ounces. I too have read about 5.5 pound pulls but mine were considerably heavier in reality when tested today. My 1911s at3lbs 6 ounces suggest the Lyman digital is properly operating. I made sure to deactivate the trigger safety for testing both glocks. The Lyman tests center of the trigger. Maybe Ayoob has some rig that allows him to test it at the extreme point of the tip of the trigger and leverage helps or something. My 1911s also tested center as they have doubles curved triggers (std type) |

How high on the trigger are you testing, I place mine on the lower third of the trigger were my finger pulls. The higher up the trigger the harder the pull. The Lyman instructions are to allow the roller to auto center on the trigger and to pull straight back. I would have to pull at an angle to get the lower part of the trigger you are talking about. That might even require a fixture to keep the thing there. |
| related story...I put a 3.5 connector in a gen 2 Glock 19...felt about the same as stock to me until I went to the range a few months later...guy shooting next to me had a stock Glock 19..I tried it out for a minute. I thought it was stuck because it wouldn't fire. There was nothing wrong with the gun I had just gotten used to the 3.5lb |

It's not a problem for me, I rest the mag base flat on my bench place the roller on the bottom third were my finger pulls and slowly pull straight to the rear.
Sounds like your tasting the pull all the way up by the trigger safety pin. That's very high like shooting the gun with your trigger finger rubbing the top of the frame in the trigger guard and barely making contact with the trigger safety. |

There was nothing wrong with the gun I had just gotten used to the 3.5lb I had the same phenomenon- limited difference, but the gauge says 3 lbs dropped off the original 9 and a half. |
| Further thinking about this it looks like ayoobs old test shows glock gauges the toe (extreme tip) of trigger. It also appears the other springs have changed (trigger return must be lighter/ striker harder). Wolf claims oem striker is 5.5 but mine measured 6.5 when I pulled the striker almost into contact with the plate on the slide. It appears that with the 3.5s geometry the striker spring dictates pull weight where with the oem connector it is 3 lbs higher than striker weight so the oem connector must create a mechanical disadvantage. |

Quoted:
The geometry of the reduced weight connector will force you to compress the striker spring slightly more than the stock connector. Posted Via AR15.Com Mobile If that is the case, does that mean the increased compression of the striker spring results in more reliable ignition with the reduced weight connector? |

The reduced connector doesn't reduce the striker spring weight and more compression means more striking force. Is this measurable in any way? If someone measured the difference in cocking length, that could be translated to a striker travel and the pull weight of the striker at those two points could be measured with the Lyman guage to discern the load weight difference in the spring from one point to the other. Off the top of my head I doubt it would be more than half a pound but that might mean something to someone wanting reliability with a lighter spring. |
