TTI Grand Master Spring Kit

[Latham44]

Recently purchased this kit for a Gen 5 G34.  Should I install all the springs (striker especially) that come in the kit?  I shoot factory ammo and probably won’t reload for a long time (if ever).  I will be using the factory striker, but was wondering if I should be concerned with light strikes on factory ammo.

I have the TTI kits in 4 Glock 34's, two of which are Gen 5.  I don't shoot factory ammo, but if I did, I would shoot American brands of ammo and try it.  My bet is that it will work with the reduced power striker spring.  If not get a Wolff 4.5 pound striker spring and that should igite all primers.  You will definitely benefit from changing our the striker spring A LOT.  I would bet money, the TTI striker spring is very close to 4#.  I went many years of competitive shooting before getting any light hits with a Wolff 4# striker spring.  I have shot factory ammo in the past with a Wolff 4# striker spring and it ignited all brands of factory ammo including CCI.  I am a big fan of Fiocci but I believe their primers are harder than the American brands. Perhaps others can validate that.

Thanks for the quick reply.  I ordered the Wolff 4.5 lb spring and I will install it with the other parts from the TTI spring kit.

Install all the springs and don't worry about it. I have installed these kits on 2 Gen 5 G34s and one Gen3 G34 and haven't had any problems igniting 20,000 plus rounds of factory and my own reloads.

Definitely try the TTI striker spring first!

TTI striker spring will be fine, just make sure you change it every 5,000 rounds. I have had problems with the trigger return spring on the Gen 4 but the others in the kit should be good to go. I would stick with the factory weight return spring regardless of generation because it has a much better reset than the higher weight after market stuff.

It already comes with a 4.5lb. striker spring, which should have no issues setting off primers with factory firing pin.

Thanks for all the replies.  I'll go ahead and install the TTI spring.  I did order the Wolff springs, but they were not very expensive, so I'll throw them in the tool kit for now.  You all have been a big help. Thanks.
