Ok im planning on ordering a Glockworx Fulcrum Trigger it comes with optional striker springs and polished safty plunger included. The goal is to reduce pretravel (the over travel is comfortable already) and reduce the trigger pull to around 3.5lbs. This item claims to be able to reduce triger pull to as low as 2lbs. My question is does the polished safty plunger do any thing at all for trigger pull and if not does it affect lock time in any way compaired to the factory? Basically is the safty plunger a good change or stick with the factory part? So you have all the info the gun im doing this to is a Glock 17 3rd gen the only change already made is upgraded to a stainless steel guid rod with factory spring I use it for daily carry. Thanks for your response.
