After a rant I thought I’d post some actual content that is worth reading. I purchase and installed a Glock New York 1 (Known most commonly as the NY1) trigger spring into my 30SF.
For those who aren’t familiar with Glock pistols or their various factory trigger the NY1 spring replaces the standard s-shaped trigger spring in Glock pistols. It does two things. First is makes the trigger pull more consistent. But more importantly, in my case, it increases the trigger pull weight. A stock Glock trigger pull is about 5.5 pounds depending on where you measure it. Installing the NY1 spring bumps that weight to roughly 8 pounds.
Increasing the trigger pull weight may seem strange, most people try to lighten their trigger. For those of you who read my previous post Two Schools of Carry Permit Holders you probably already know why I dropped in the NY1 trigger. For those who didn’t the reason is to avoid a charge of accidental discharge in a self defense situation.
I like taking advice from people who have experience and knowledge greater than mine (In other words almost everybody). I’m reading Combat Handgunnery by Massad Ayoob. In the beginning on the book he talks about various popular guns. In the section about Glock pistols he mentions he has and often carries at Glock 30 with the NY1 trigger spring in it. The justification made sense to me. It increases the weight of the trigger pull to such a point that a lawyer is going to have a hard time claiming you accidentally shot a person.
This is an argument that has been used before when a police officer had to use his gun in self defense. In the case the officer was accused of pulling back the hammer of his revolver making the trigger pull weight almost nothing. The lawyer then continued to argue that the police officer most likely didn’t mean to pull the trigger but accidentally set it off during the excitement.
Well I really don’t want that kind of trouble. Increasing the trigger weight isn’t a problem for me either. My first handgun was a Smith and Wesson 686 .357 magnum. Although it has a hammer I almost always shot it in double action. Likewise my Ruger LCP is double action only. I’m used to heavy triggers and my accuracy (What little I have) isn’t hampered by them. So long as the trigger is consistent I’m pretty much set.
Installation of the trigger also reaffirmed how simple Glock pistols are. I’m not going to write out how to do it because it’s something best put in video form. Luckily Eric Shelton from the Handgun Podcast already made a video about doing exactly this. So here it is:
Anyways with the NY1 trigger spring installed there is a noticeable difference. The trigger is heavier and requires more force. With that said it’s still comfortable to pull back. I think increasing the weight much further wouldn’t gain much benefit as the NY1 trigger spring adds enough weight where I feel a negligent discharge is doing to be unlikely. Furthermore the NY1 trigger spring is built heavier than the factory spring (Which is just a spring) so it will probably last longer. Overall it’s a good, cheap (The part is under $3.00), and easy modification to make.
The trigger also lacks the various pull weight. The factory Glock trigger seems to get heavier as you’re pulling it back (I’m not referring to the slack at the beginning of the pull but when the trigger starts exerting pressure). I know quite a few people put in a NY1 trigger spring with a 3.5 pound connector to gain a more consistent trigger without increasing the weight. I can definitely see why that is done, although I don’t see the gain being worth the cost of the 3.5 pound connector (Which is actually fairly expensive for a Glock trigger part).
