To bad you are not going to be able to make it to ShootzenFest you could try the trigger on my home grown race gun.
I would do a 25 cent trigger job and a 3.5 Lone Wolf connector to start.
Mothers Mag and Aluminum polish works really well, Flitz or even rubbing compound will work.
This is what I do to ALL my Glocks.
It is the most bang for the buck.
Very few people do not like the 3.5 connector.
If you want more then you might want to use a 6 pound Wolf trigger spring and see how you like that.
On a a defensive gun I would hesitate to do much more.
I prefer a smooth trigger so I change them out first thing.
On my Glock 36 I reduced the trigger grooves to nearly nothing.
I always cut down the trigger drop safety so it is almost to completely flush with the trigger face when I put my finger on it.
I keep reading about people using a NY trigger spring with a 3.5 connector and saying how great it is.
Well let me tell you it sucks.
I tried it and have no use for it.
Dirk Pitt also tried it and did not like it.
