Glock’s part number for the Gen4 G17/22 trigger is 3608.
Glock’s part number for the Gen3 G17/22 trigger is 357.
Beware, early G19’s (pre EH serial numbers) need a special trigger, DO NOT use the #357 trigger in these early G19’s!
I always put the smooth faced triggers in my compact Glocks. Feels much better!
Although my neighbors are all barbarians,
And you, you are a thousand miles away,
There are always two cups on my table.
