No problem at all! Although I wounder the real benefit of the 3.5 lb trigger over the 5.5? But whatever! Most good holsters also protect the trigger area from being snagged on anything. That would be the only issue with the trigger even being lighter as well as the standard or NY Trigger! As Chris stated to get the Glock to fire the trigger safety mechanism on the face of the trigger must be depressed as well as the trigger pulled to the rear. Carried one for years on duty when I was working and today for CCW.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
If it's a CC self-defense piece, the thought of the 3.5 pound connector terrifies me personally, but that's just my opinion. I no longer own a Glock, but considered having both of mine fitted with the 8 pound "New York" trigger. In the stress of an emergency situation it seemed to me that the more definite a decision to fire was required, the better. I don't even want the option of single-action revolver fire for self defense, so my EDC is a concealed-hammer J-frame. If, God forbid, I have to fire, I want to be very sure it's on purpose.
Of course YMMV, and I'm sure many knowedgeable people will violently disagree.
I know, the answer is keeping your finger out of the trigger guard till ready to fire, but adrenalin can be a damn tricky thing.
While my Glock has the stock 5.5 trigger, I personally don't feel the need to go to the 3.5. So I'll say depending on the training, equipment and maintenance the 3.5 trigger should be every bit as safe as the 5.5. The function is the same with just a lighter pull. If it floats your boat go for it.
Don't question my right to own a gun and I won't question your stupidity not to.
You give Peace a chance, we will cover you if it doesn't work out.
Any gun modification you do could be fodder for lawyers if you ever shoot anyone . I would avoid unnecessary modifications but if I thought something would make the gun a lot better, I'd do it and risk the lawyer games .
