All measurements are with a walmart fish scale and coat hanger, but I did check the fish scale with calibrated weights from work. It was low by 1.5lbs from 3# to10#. All my numbers are adjusted as such. I tried to put the hanger in the same spot (where my finger goes) every time, but that was hard. I always pulled straight back in line with the bore. You could milk the angle to get lower pulls, but I was careful to NOT do that. I also did NOT put the hanger on the very tip of the trigger ever. This cheats the numbers.
Review of the Gallaway Precision GP-1800 Spring Kit for Glock 42. My gun had been through about 300 rounds before this. 1 Glock 42 Factory – 9 to 9.5lb hard but crisp and resets fast 2 GP Striker spring and firing pin blocker spring --- 6.5 to 7 lbs. Trigger safety blade does not quite reset, but it is close. Pull feels MUCH better 3 Added GP trigger bar spring – 5.75lb. VERY NICE TRIGGER. Easy to pull and less “rub” than factory. However, the trigger safety is nowhere even close to resetting. 4 Replace factory trigger spring, perform fluff and buff ---6.25 to 6.5lb, still a nice trigger, but the trigger safety is not quite resetting. 5 COMPLETELY removed GP parts. Installed Wolff reduced power firing pin plunger spring and installed Wolff 4lb striker spring ----6.25 to 6.5lb pull and acts just like “step 4” above. 6 Wolff 4.5lb striker spring ----6.55 to 7lb trigger pull and trigger safety barely resets no matter how you hold the pistol. This is how I left it, but I may be putting in a different striker spring soon. My trigger feels much better at 6.5 to 7lbs, but the 4.5lb wolff striker spring has caused 3 light primer strikes in 150 -200 rounds of Tul ammo. I just got some WWB, I will see if it has trouble later. The GP striker spring had a much smoother finish than the Wolff and the GP also did not bind/kink up as bad as the Wolff. The Wolffs seem to rub the striker channel a bit. The GP did not. Both the Wolff and GP striker springs are of much thinner diameter material than factory. I would say the GP spring was of a better quality than Wolff, but Glock uses thicker springs of softer material that only barely kinks. I have talked with Gallaway and they said they have only had 3 kits returned for this problem. They think its user error, but I am a “Glocker” for 12 years now. I have had a “glock” tackle box of parts for years and know what I am doing. My G34 has a 3.75lb trigger with an adjustable overtravel trigger stop made from a small bearing and 2-56 set screw. I can tinker. I did nothing wrong on this install. I then tried the kit in another brand new Glock 42 and it was the same story only worse. It had to have a Wolff 5# striker spring to function the trigger safety. Gallaway has tried 5 test guns and theirs all work with the kit. CONCLUSION The Kit makes the trigger much lighter, and a fluff and buff gets rid of the factory grit. It sounds like most guns work just fine with the kit, but I will return mine. Both 42’s I tried were brand new or near new and maybe glock is putting more pressure on the trigger spring via that little clip than on the older models. I dunno. If you install the kit and the trigger safety bar is only barely failing to reset, put the factory trigger spring back in. The total pull will go up, but you might get full reset. Mine did not. You could also cut a coil off the factory trigger spring to get full reset. I don’t know where to get replacement factory trigger springs yet, so I did not try this. You could also bend that little clip back a little to put less trigger spring pressure to the rear, but again, no spare parts supply for if you screw it up. If the kit works in yours you will be very happy. If not, just return it or tinker as you please. With only 3 returns out of many sold, the odds are in your favor. I never fired a shot with the Gallaway parts in, so I can’t comment on how it actually fires. NOTE Glock 42 seems to use a standard Glock 5.5lb striker spring and standard Glock firing pin block spring. Firing pin spring cups look the same as my spares, but I did not try my spares out. |

Quoted:
the factory 42 trigger weight is 9+#?!! I didn't measure mine but I am 100% certain it is heavier than my Glock 26 with an 8# connector. So at least 9 pounds sounds right. My 42 is back at Glock for inspection so maybe it will be closer to the advertised 5.5# pull when I get it back. |

This design can not go as low as 5# without a connector with a lower angle. Glock seems to be moving the striker less distance than on all other models, which means you need more spring power to accelerate the striker to speed over the shorter distance. Also, the pushing spring is pretty stiff. Its big advantage is that the angle the spring pushes improves as you pull the trigger so the trigger seems to kinda of collapse to a quick fire once you hit the connector. Standard pull springs (all other glocks) just kinda neutral out angle wise when the trigger bar hits the connector but 3.5# connectors are everywhere as are stiffer trigger springs and reduced power striker springs that still ignite. To get this trigger lower and reliable ignition, I would stay add a couple of small washers or a tubing type spacer in front of the trigger spring. Good luck installing that

| Maybe you should take the fact that you are getting failures to fire and a safety device that will not engage as a sign from above to leave the gun stock. Both of min are just fine out of the box even if the trigger pull is a little heavier than my other Glocks. |

Good luck installing that glock should advertise the trigger weight accurately. If they say it's 5.5# then make it between 5-6 pounds. If the design means it has to be much heavier then tell people its 9# |
