Glocks do not have hammers or hammer springs.

What does a heavier trigger return spring do other than make the trigger heavier? I put a lighter return spring in my G23 and it took about 1.5# off the overall weight without effecting anything else.

My two recent converts:



These two join two previous ZEV-triggered Glocks. I expect them to perform just like my previous pair. The ZEV doesn't really clean up the mushy nature of a Gen4, but the pull is smoothed considerably, the break lighter and crisper. Both these two are complete ZEV trigger sets, whereas my earlier ZEVed guns were done only with ZEV trigger bars in conjunction with factory parts and aftermarket bits (like the connector and springs) sourced from others. The MOS G19 as currently configured is most definitely the scarier trigger of the two.

In the MOS I went ahead and installed ZEV's 2lb striker spring and their striker safety plunger and accompanying spring. This strictly range gun (in this setup) has a 3 to 3 1/2lb break according to my manual Wheeler gauge. Takeup is a bit spongy but very smooth compared to factory setups, and you just roll right through the break as the stacking point isn't particularly firm or sharp. However this is a trigger that still can be staged, but it's uncomfortably easy to unintentionally set off with this one, as I've encountered with dry fire practice. Before I get serious about live fire, it may get a return to stiffer springs to heavy up the pull and break.

Off-topic, sort of: I've just gotten the gun put together as the replacement MOS #2 plate courtesy of Glock CS arrived today. Actually they surprised me by sending the ENTIRE MOS plate set, and not just the #2 plate that I broke and subsequently asked for. However the set I ORDERED from Glock's online store is nowhere to be found; the last email I received from Glock was that it would arrive by June 1, a whole two weeks from when the order was initially placed. Honestly, I didn't realize that FedEx had services that SLOW.

Back on topic, well sort of: the regular Gen4 G19 is the one with the Bullseye sight. Originally I was going to leave the gun stock but I had this ZEV trigger set just lying around doing nada, and one thing lead to another. It's definitely got a heavier pull that breaks around 4.5 to 5+ pounds. Without modifying anything else, the takeup is definitely notchy in comparison to the MOS trigger setup. I prefer its break weight better, however; feels less that a disaster is about to happen with this one.

With my MOS on the sidelines until today and life getting in the way as well, I haven't taken either to the range yet. It going to be interesting to shoot these two side-by-side. Hopefully in the next day or so...

I'm sure someone more knowledgeable than me can explain, but I don't believe the Glock trigger spring is actually a trigger "return" spring. The standard coiled Glock trigger springs work against the striker spring and assist trigger pull. The trigger spring is under tension before the trigger is pulled and works with you. A heavier trigger spring and/or lighter striker spring will reduce trigger pull weight. The trigger reset is done by the striker being released and moving forward not the trigger spring. The NY style trigger springs work differently. A heavier NY spring will make the trigger pull heavier.

Did you do anything to the striker itself? I get light strikes on anything other than federal primers with Zev's 3# striker spring that comes in the "competition" spring set.
