Home Guntinkering Do's and Don'ts

For the Do's

The PA-63 has a terrible stock trigger pull, requiring fingers of steel to get a shot off in double action.

So I purchased a Wolff Gunsprings Hammer spring pack and decided to change the spring.

I went with the middle weight 11 lb spring.

Changing the hammer spring is simplicity itself:

1. Ensure the PA63 is unloaded and remove the magazine and remove the grips;
2. Tap out the pin on the bottom of the frame;
3. Take off the plug at the base of the frame now freed by the removed pin;
4. Take out the old spring, replace with the new spring making sure the hammer strut is inside the spring;
5. replace the plug and pin, and screw the grips back on.

The whole process takes maybe 5 minutes.

The improvement is immediate and remarkable.

The PA-63 is now practically PPK-like in trigger quality, I may go to the 9lb just to see if it becomes even better once I test it fully at the range.

If you own a PA-63, you really owe it to yourself to get a new hammer spring set and get it installed.

As for the Don'ts:

The Glock factory extended slide stop release for the 3 pin Glock frame does not work when installed in a two pin Glock frame.

It will cause the slide to lock open after every shot which is rather embarrassing.

Ask me how I know.
