They aren't difficult to install... You will need to detail strip your Glock to install it though...

I wouldn't think it would void your warranty - it's a Glock part... You might want to call Glock to make sure...

 

+1 __jb is exactly correct. You may be surprised at how quickly you can adapt to the stock trigger configuration. Enjoy, Be SAFE.....Shoot WELL

 

Here is how i install anything on a Glock except for a Grip Plug which I can actually do myself.
"Hello Mr Gunsmith can you install this for me"? ;}

 

If you can detail strip your glock you can install the NY1. Just remove the stock coil spring and substitute the NY1. It snaps in place. Hard to do it wrong. I does not void the warranty.

That video makes the statement that Glock says that the only way to use the 3.5# (or 4.5#, take your pick, same part) connector is with the NY1 (Olive) Trigger Spring. I believe that is not correct information.

Here is the trigger pull chart from the current Glock Armorer's Manual (© 2009), that clearly shows the NY1 (olive-colored) trigger spring used in combination with either the standard or "-" marked connector. It also shows the "-" marked connector in the configuration that most of us use it with, the standard trigger spring.

I would also add that the "-" connector is shipped with the standard trigger spring in the G34 and G35, and perhaps other models.

In my Armorer's class this topic was discussed, and I recall no mention of any prohibition on the use of the NY1 (Olive) or NY2 (Orange) trigger springs, other than to say that "A New York spring should never be installed with the 8 lb. (3.5kg) (+ marked) connector."

Well, how much confidence can you have in someone who says he dragged his pistol behind his truck (presumably for a video) ..
