Optimizing FN/Browning Hi Power

[mtenenhaus]

it's time to do some maintenance and possible improvements to my Hi Power.....plus it gives me a great opportunity to take the pistol all apart, check everything out, give it a good cleaning and keeping it in tune....i really like the pistol. It's completely stock with the original parts, one of the Israeli pistols that came to market a decade ago. Interestingly it came with the round, commander type hammer.

I found both Wolff Springs as well as BH Spring Solutions offer replacement springs for the platform.

Wondering if anyone had any experience with or concerns regarding either or both.

Improving the quality of trigger pull and reset would be great but maintaining reliability takes precedence.

thank you

Hone the sear and hammer surfaces but keep stock geometry and spring weights.
When you shorten the engagement too much or re-spring lighter, that's when you run into reliability problems.

The power custom hammer and sear stoning fixture is your friend.

As long as it's working, I'd save the springs for later. When you put it back together, you may wish to consider leaving out the magazine safety as that will markedly improve the trigger in most cases.

With mine, I replaced the hammer and sear with aftermarket parts. Upgraded the hammer spring, recoil spring,and installed a flat bottom firing pin stop. Removed the mag safely, which requires replacing the trigger return spring to a heavier version.
Then I stripped the epoxy based finish off, and Parkerized it.

as always thank you to everyone, planning a judicious polishing. appreciate the help, will save everything.

Sailormilan2....looks great.
how do you like the safety? is it an ambi safety? which manufacturers parts and springs did you purchase?

looking forward to the project.

Cylinder and Slide “No Bite Commander” style hammer and their sear. 34# Hammer spring and recoil springs is a couple of pounds heavier than stock factory. 2 coil trigger return spring(It might be a 3 coil. It’s been a while since I did it). Browning Ambi Safety, for its slightly smaller profile. I also removed the lanyard ring.
Getting the epoxy based finish off was a real PITA. Bead blasted everything, then polished the slide flats with 400 grit paper. Parked it 3 times before I got it right.

Easy to install. Right hand lever is held in place by a very small roll pin. The Browning safety is a slimmer profile, so you have to concentrate a little more on it when dealing with it.
