Glock 43 Repair Work on the Firing Pin Safety Spring

A friend owns a Glock 43 and he said the trigger pull broke at 8 pounds. He took it to a dealer and one of the guys that worked at the shop took the 43 apart and polished some parts. He also cut a coil off of the firing pin safety spring. Is this kosher or dangerous? I have never heard that this spring needed to be shortened. Thanks for any input.

The best thing you can do with a new Glock to improve the trigger is to shoot it.

Barring that cutting springs on guns is almost always a sign of a bad gunsmith. OEM springs are made to certain lengths and often one spring works against another in a way that is best understood by an engineer.

Wouldn't do what your buddy had done to any of my Glocks. If I think a spring is too heavy or light I usually buy a spring kit from Wolf... Or I replace the connector with a custom connector or even a lighter OEM version from Glock which may or may not be available for the G43 yet. But cutting springs and polishing surfaces especially on critically hardened parts is a recipe for malfunction.

I would rather have used a reduced power safety plunger spring but, cutting the coil spring may be getting it close to the weight of the reduced one. You usually see people cutting the spring on a magazine but, not a safety for liability reasons. Might be fine function wise. I would not put my John Hancock on it though.

I guess I do not get out much but I have not seen anyone cut a magazine spring. And I would pass on having anyone cut any springs.

I appreciate the input. I would still like to know if this could be a dangerous fix on the firing pin safety spring? Could this pistol fire without pulling the trigger or any other concerns. The reason I am concerned is I may purchase this 43 and would like to know what I am getting into. Thanks again.

I wouldn't let just any Bubba cut my springs. That's because I prefer to do it myself. I have cut a coil or two from just about every Glock firing pin/striker safety spring I've had in my Glocks except when I get those reduced power ones that come with some of the drop-in triggers like Zev etc. I found that using a reduced power spring eliminates the peening that occurs when the firing pin/striker hits the safety. It may also smooth out the trigger pull a little.
