Hi Power trigger

[Rosereader]

So my granddad's Hi-Power (which I am the proud owner of) does have one key issue. Well, it has many issues but this is the most important.

The trigger is terrible. Has about 1/2" of just loose springiness which I personally just depress until you hit the actual mechanism which pulls at about 6-7lbs. It is horribly jerky and has led to my moving the front sight off target during firing. Now I've never been a great shot with pistols, but my experience with single action revolvers shows that with a good trigger I can hit my targets...

Now I know my auto will never be as good as that, but does anyone have any recommendations? Is there a new trigger spring out there that could help? Anything?

If you have the magazine safety removed that will lighten your trigger pull a bit.

Removing the magazine disconnect will help a lot.
Other then that the only thing you can really do is run a lighter main spring. (Go ahead and get the whole Wolff Performance Pack)

Neither of these mods are really easy to do, but are possible given a certain level of mechanical skill, access to tools and luck.

Bare minimum you need a set of punches and if you are doing the mainspring a bench vice. If your trigger pin won't come out then you will probably need an automatic center punch (good one, not a harbor freight special like I first tried), penetrating oil, a BIG heavy hammer, time, patience, luck. And maybe even heat or cold.

If its a blued model it shouldn't be too hard to remove the disconnect but if its an epoxy black paint finish it can be a bear! Trust me, I've been there myself and talked many others thru it as well.

The lightened mainspring will require a complete detail strip of the frame, except the trigger parts...
So you might as well do the two mods at the same time and fully strip it, hah.

If its not challenging enough to do a complete detail strip then the actual procedure of replacing the main spring goes something like this: remove tension from the spring (this is where a bench vice comes in handy), tighten the collar, remove the tiny tiny tiny pin, loosen the collar remove the spring. Replace the spring compress the spring, over tighten the collar, replace that impossibly small pin, then screw the collar to the right position.

Helps to have 3 hands but then again theres no room for even one hand to do these tasks..



Good luck, BTW if Grandpa's pistol has any historic (ww2 maybe?) or happens to be an expensive/special model, you may not want to try any of the above and keep it correct...

I always wondered if the GP Competition fire control pieces could be put in a standard Hi-Power. They have very decent triggers comparable to a 1911.

Hey, thanks for the advice on the springs.
I've had to strip it before, when I got it the whole thing was rusted tight. Ended up having to fabricate a new hammer strut assembly pin, being too cheap/impatient to bother buying one.

Honestly I think grandad already removed the disconnect... I have no problems firing it less magazine.

And no, it sadly does not have any value as a WWII piece. It's from the 70's.
It is blued though. Poorly.
