If you want to find out what trigger set up is in your Glock, there are two ways to do it. If you bought it new, you have the box it came in, and the label is still on the box, you can check the label to see what trigger the gun was shipped with. Most Glock labels will say something like '5lb trigger' or '5.5lb trigger' as that's what they ship with unless they are the longslide 'competition' guns which normally have a 3.5 (or 4.5) trigger, or if the gun is special ordered with a different trigger set up. The other way is to compare yours to the pictures below to see what's in your Glock. Older Glocks might have a NY spring in them that is black or white in color too. Wanna kill these ads? We can help!
