I have it installed in my M&P 40c carry gun. Truthfully I don't see the problem with a lighter trigger. You shouldn't have your finger on the trigger unless you are ready to fire on the intended target anyhow. It isn't as light as you would expect either. And as for something putting pressure on the trigger and accidentally discharging the firearm... The difference between 5.5lbs and 4.5lbs isn't going to matter. Looking forward to other peoples opinions on the subject.

There are no cases in which a modified trigger was ever used against a defendant unless there was color to the case (gang relations, illegally modified weapon [think:NFA], etc.). I don't know why such an internet myth still carries on...

Additionally, it is highly likely that you would encounter someone who carries a 1911 on a daily basis (me) to have a trigger which breaks at 3.5-4.0 lbs.

Enjoy your gun, train with it, and carry wisely & happily.

I just don't understand peoples problems with a lighter trigger, and especially only the difference of 1lb. It will allow a person to be more accurate and have quicker follow-up shots. A persons finger shouldn't be on the trigger until ready to fire in the first place. I just want to know peoples opinions and reasoning behind having heavier triggers.

So, did you use the 4 pound trigger spring that was provided in the kit?
I am thinking about buying this for my compact. Was it hard to install?

Pretty easy with all the youtube how to videos from APEX.

But yeah a light trigger is fine to carry IMHO (I do it with no safety) a good holster with good retention is the only safety I want when I need it.

It looked like a rather easy install, but with it being my carry gun I had a gunsmith install it. I love it and would like to install the kit in my FS M&P 9.

I think in a clear cut case of self defense there is no jury that will hold something like that against you. like mentioned above plenty of people carry guns like a 1911 that have a factory trigger around 4lbs. what is the difference between a factory 3lb trigger and a modified 4.5. to me I just feel like thats people over thinking things. however my statement has no real merit because im not a lawyer nor I ever shot someone in self defense with a modified weapon.

I would suggest reading what Massad Ayoob has to say about modified triggers and court cases. This guy is not some internet guru, but rather the real deal when it comes to expert gun-court issues.

There are two issues here. Intended fire and accidental fire. If you honestly think a few extra pounds of trigger pull provides some level of protection against accidental fire and that this level of protection is more important to you than the added ability to shoot well that comes with a reduced trigger pull, then don't modify the thing. If you're debating whether or not a shoot is justified, the trigger pull weight is entirely irrelevant. Carry what you feel is the safest option considering safety and ability to hit what you're intending to shoot when the time comes and forget about the rest. The Zimmerman fiasco has the CCW community convinced that if you pull the trigger you're going to end up defending yourself in court. A vast majority of justified shoots never even get the prosecutor's attention. Carry what you shoot well and let the chips fall where they may otherwise. I would also be wiling to bet that the investigators and prosecutors aren't even aware of or will notice things like modified internal components and trigger pull weights unless they are also gun nuts, in which case you're already good to go if the shoot is justified.

tldr: version. modify whatever you want, don't make dumb decisions, hit what you aim at, and you're good to go. If you consider trigger pull weight a safety feature, you already lost.

Carry what you want. The national recommended standard for police pistols is a minimum of 5# trigger, if that matters to you. A lighter trigger will not make a good shooter out of a poor one.

My issue is that WAY TOO MANY PEOPLE WITH LITTLE TRAINING absolutely KNOW that a light trigger will make them shoot better in a highly stressed shooting scenario. My experience with the SIMULATED STRESS of a defense scenario is that the typical shooter from the public range (a legend in his own mind) can shoot very rapidly but WITHOUT HITTING MUCH OF ANYTHING. Many are very proud of how fast they can shoot with their modified light triggers standing flatfooted at a firing line. In a timed shoot and move scenario, they often fall apart and just spray and pray.

So TRAINING and PRACTICE are the issues. A very good instructor for the police dept in a nearby town (who is a regular competitor) brought some of his young officers to my IDPA match to motivate them to take their pistol training more seriously. After they were soundly beaten, even by the old gray heads, the young officers got the point. First good hit usually wins the fight.

Your "real deal" is correct about one thing. If one has his finger on the trigger, he is more apt to have an AD with a light trigger pull. The rest of his statements about lighter triggers though, is nonsense from his imagination.
