If there is no difference in effective accuracy but serves to reduce the likelihood of unintentionally shooting yourself and others... sounds like a genius win/win upgrade to swap out your 5-6lb Glock trigger to a 10-12lb, right?
Kmb6893, you've posted that you have owned Glocks. Did you swap them to 10-12lb triggers upon purchase?
There's lots of Glock owners here.... Who here has changed the trigger in their Glock to 10-12lbs to reduce the likelihood of unintentionally shooting yourself and others?
I must admit that I've been a Glock owner for a couple decades and have yet to "upgrade" ...
My Glock 19 came with the NY trigger and I never changed it. My Glock 26 came with the standard trigger. I didn't own it for long but I never changed the standard to a NY one. I shot them both equally well. The trigger made no difference that I could see. The torso of a man sized target was shredded with both.
Gaston Glock came up with his "Perfection" slogan and people swallowed it whole.
And I would bet that most gun owners don't tinker with their guns. If they stop working they send it back to the factory, but that's very rare. Most people buy a gun, shoot a few boxes of ammo through it, and put it in the sock drawer. They don't even shoot it enough to know if there are problems. I know people who carry who haven't fired their weapons in over a year. Smart? Nope. But it is what it is.
Most gun owners aren't members of gun forums.
And the average guy buying a Glock in a store has no idea what trigger weight is, nor does he care.
A friend at work wanted a gun for home protection. Neither her nor her husband are gun people. So she says "the clerk at the store told me I should get a Glock". So I invited her over. Showed her the difference between striker fired guns and hammer fired. I no longer own any Glocks but do have a Ruger SR9 and an LC9-S. Both have pretty light triggers, but they have manual safeties, too. I told her the Rugers were very similar to the Glock but they have manual safeties and magazine disconnects. She liked those features. But she was shocked at how easy it was to pull the triggers.
She liked my Beretta 92 and S&W 5903 the best. Said they were "prettier", but she liked the longer trigger pull on them. Wanted a 5903 but doesn't want to buy used, so she's going to get a Beretta 92fs Compact. She liked the revolvers too so she might get one of those, but she decided against a striker fired weapon of any brand.
The same mantra is repeated over and over again. "Keep your booger hook off the bang switch", and "my safety is between my ears", and judgements of those who have used a weapon in high stress self defense situations by those who never have and never will. YouTube is full of them as they make their videos from their mothers basement. Nobody here is saying a heavier trigger will PREVENT all ND's. But it will reduce them. There is no denying that. Before Glock graced the world with their presence, people carried semi autos with long DA pulls and even safeties! And many even used them in self defense situations! And they worked just fine! And the term Glock Leg didn't need to be coined.
I no longer carry a gun for a living. I carry a Ruger LC9-S because it is the slimmest and lightest 9MM I could find. The trigger on it is very light, but I has a safety and a mag disconnect and truth be told, it gets loaded and holstered with the safety on and it doesn't come out again until I get home. I had the older LC9 and sold it to buy something else. I should have kept it. Long DA pull. The LC9-S was cheaper when I bought it for some reason. I would never buy the LC9-S Pro, the version without the safety. The trigger on the LC9-S is extremely light and short.
Cmort's aversion to a heavier trigger is because he likes to think of himself as some experienced gun handler, and a heavier trigger is an insult to his perceived abilities. He can't clearly state why the heavier trigger is worse in a self defense gun. He just keeps repeated "training training training".
