I was using the SSVI trigger in my G19, which seemed to work excellent but when I bought some German NATO ammo with some rock hard primers, I started getting light strikes.
The resident Glock guru/gunsmith at the gun range told me that you can have light strikes after replacing/working on the trigger. That doesn't seem to make inherent sense to me, but after I restored the trigger back to stock configuration, the problems stopped. |

In my experience this is usually the lighter striker spring that causes the light strikes. A lot of trigger jobs use a 4-4.5 pound striker spring which can be problematic YMMV |

My experience (with Zev trigger kits, only on my 9mm Glocks) has been such that reducing the strength of the striker spring would necessitate the use of the lighter striker (also offered by Zev) to avoid light primer strikes. This is completely dependent on your choice of ammo, as primers differ in "hardness".
I load my own ammo, and have found that CCI primers are harder than Remington or Federal. With CCI primers in my loads, I was getting light strikes consistently with the lighter spring setups. Ironically, the same spring setup would work pretty well with CCI factory ammo (Blazer Brass). I now have the 3lb spring, Zev Striker, and am using Remington primers and have had zero issues. Long story short - if you reduce the weight of the striker spring, you may also have to reduce the weight of the striker itself to generate the same velocity in striking the primer. |
