Glock Trigger Work

Many people have trigger work performed by a gunsmith at their local gun shop. Fortunately the design of the Glock pistol is simple enough most gun owners to do it themselves, if they want to. It involves the removal of the trigger assembly, the firing pin assembly and firing pin safety. Once removed certain parts are polished smooth. Other parts (like the connector and springs) can be changed out to achieve a smoother trigger pull. The first time I did this it probably took me 2 hours or so (the learning curve). Now I can do in about a half hour. I took the following pictures and wrote down the steps it took me just in case I forget.

FIELD STRIP THE PISTOL

Field strip per procedure Field Strip Instructions. (While it's field stripped with parts removed, this is an excellent time to clean and inspect each part)


REMOVE THE FIRING PIN & FIRING PIN SAFETY

Remove from the slide per procedure Slide Disassembly & Cleaning. Be careful when you remove the back plate on the slide. Springs are under compression and may fly out, if not removed carefully.

DISASSEMBLE THE FIRING PIN ASSEMBLY

Disassemble into it's component parts per procedure Firing Pin Assembly/Disassembly Instructions. (Taking it apart is easy, the tricky part is putting it back together).

REMOVE THE TRIGGER ASSEMBLY

POLISH THE TRIGGER BAR

Polish the three different surfaces as shown. Basically you want to smooth out and polish those surfaces that come into contact with other parts. Caution - do not remove any of the metal, just polish the surface smooth.

CLEANING & Reassembly

Clean all removed parts. DO NOT OIL THE PARTS AFTER CLEANING. Oil will just make them a magnet for dirt and contaminants.

Re-assemble and reinstall all parts per procedure Trigger Removal & Installation Instructions.

When you talk about polishing the connector are you talking about the factory connector or one of the after market connectors? If the later, how and what section(s) needs polishing?

Response - Jack, I would polish which ever one I had. They are almost identical. The surfaces that need polishing can be found here. I use a Dremel with a polishing/buffer pad and polishing compound and I use great care not to scar or remove any metal from the surfaces that I polish.

Reply - Tanner, I have both Glock 19 and 23 and have installed the Ghost spring and connector sets in both pistols. I just thought that they had already been 'polished'. I saw your instructions almost immediately after asking. Will give it a go and check back later. Thanks for your speedy reply. I appreciate your web page and all the super information you have on it.

Response - Hobert,

Sorry, I don't know what you are talking about.

I think I have documented all trigger components associated with my G19.

Best regards,

Tanner
