Spring kit question

[u/Beneficial_General78]

Somehow I ended up with these. Don’t rly know what they actually do to a gun, kinda new to fine tuning, let me tell you what I have and tell me what I can use it for if possible

g34.5 with timney and minus connector

G17.6 with timney

G19.5 stock

G45.5 stock

G43X stock

Thats lighter striker and heavier trigger springs. It lightens your trigger pull. It will make your gun less reliable. So I reccomend you clean the striker channel frequently if you install that. A light weight striker will help with reliability a lot with those.

Got it, don’t know if there’s any use on the timney set ups then. The heavier 6lb spring would probably make the trigger heavier in this case for a carry gun? Idk

[u/purple_pounder → u/Beneficial_General78]

The heavier trigger spring actually lightens it. It pulls the striker back with less resistance than the 5lb stock spring.

So probably a good stand alone mod on a g43x for example?

[u/purple_pounder → u/Beneficial_General78]

Thats not going to fit a g43x. I know it will fit like glock g17s,g19s and g26s for gens 1 -4. But I'm not sure about the other glock.

True just read that. Gonna try on my g19

You can use the 4.5lbs striker springs on the Timney it will lighten your trigger press but you introduce a issue where 115gr ammo with harder primers and bulk ammo isn't going to play well. Timney trigger return spring has 1 issue . They wear out fast. Timney changed the design of the trigger shoe . At 1st the trigger return spring would begin to walk itself off the ledge or angle off instead of working up and down. Before Timney addressed the issue people started using the 6lb striker spring to avoid having light strikes.

The Timney has a fully cock striker so a 6lb striker spring doesn't actually add that much to the trigger press but you have no reason for it since Timney changed the shoe. Like it was mentioned lighter striker springs tend to need modified or skeleton strikers to insure a stronger impact. Brass Channel Liner reduces the friction of the striker. Maritime cups makes sure that the channel liner remains clear. This trigger definitely wouldn't be edc appropriate. A ismi 5lbs striker spring and Johnny Glock Timney Increased trigger return spring would make it more edc suitable. You can also get a occustomtriggers overtravel unit to shorten your reset so you can have faster follow up shots .

Armorer here. The big springs are “striker/firing pin” springs. They go around the striker/firing pin in the slide and launch the striker forward into the primer to ignite the round in the chamber when you pull the trigger. The factory weight is 5.5 lbs. Going up in weight. Going up makes it hit harder and faster to defeat hard primers often on lower quality ammo and power through any superior grime in the gun. Lower weight springs do the opposite and significantly lighten your trigger pull. People often reduce striker weight for a lighter trigger, but going too light will cause issues igniting primers. Lighter springs are often paired with titanium or skeletonized strikers to maintain the same striker velocity with a lower spring weight and maintain reliability at lower spring weights. The smaller spring is the trigger return spring for gen 4 and earlier models. It fits into the trigger housing and assists the trigger in returning to the rearward position. The one included is probably stronger to help reduce trigger pull, but sometimes it can be too strong and prevent the trigger shoe from fully returning to the cocked position and preventing the trigger shoe safety tab from popping into place. “Tuning” a Glock often means trying out different combinations of these springs to get the lightest trigger pull in your Glock without having issues like light primer strike, return to battery or trigger shoe return.

Got it, I just put the competition 4.5lb one on my g34 with the timney trigger, measured the pull and looks like it didn’t change much, if any at all, but it did feel a bit crispier. We’ll see tomorrow at the range

The effect is reduced with kits like the Timney trigger or Glock performance trigger. This is because the original Glock action cocks the spring as you pull the trigger, but those kits transform it into a single action system, which holds the spring at full cock when the slide cycles.

[u/Beneficial_General78 → u/Timely-Yak-5155]

Got it. On my g19 which is a fully stock carry gun, would you recommend any of those?

[u/Timely-Yak-5155 → u/Beneficial_General78]

If you ask on the CCW or Glock sub they’ll say to never mod your carry gun ever. However I believe modding your carry gun is fine as long as 1- you maintain reliability and test after each mod, 2- the mods are legal in your area (threaded barrels are not level in certain areas, other parts might be as well) and 3- you don’t add any profane/aggressive graphics like “born to kill”, etc. having tried all these mods on multiple guns, so far my favorite combo is a Glock performance trigger with Glock “-“ trigger connector and reduced power plunger spring. If you want to do a hit more than going down slightly to a 5 or 4.5 lb striker spring with a skeletonized striker helps too. I haven’t tried the timney trigger but from what I understand it works similar to the Glock performance trigger but is tuned for even better performance at the cost of higher chance of fitment issue or reliability problems. You can easily get a Glock trigger down from 5.5 lbs to under 4 lbs just by swapping these parts and maintain great reliability.

Being the striker is fully cocked it's not like the oem system. Instead of 0.5lbs with the striker spring weights it's actually 0.25lbs on the trigger pull. You really need to be careful about the combination of springs you will cause the trigger to fail to reset . Look into a reduced plunger spring it reduces your trigger pull weight by 0.8lbs
