Improving the FEG PA63 action

True story! If any of you have/had one of these or have at least handled one stock, the trigger makes a Sigma feel like a custom 1911. The trigger in SA has every negative trait; long, gritty, creepy, and really high resistance. In DA, there are those who do not have the might to even pull it through its sweep *cough*1911 shooters*cough*. All joking aside, its pretty bad and i had no idea what it would be like before i ordered it (but for $140, who can complain).

The first thing i found was a set of Wolf springs for the slide, hammer and firing pin that purport to reduce the trigger pull and tame some of the slap-sting from the recoil so i put an order in asap for a set. I then took it apart to see what can be done to smooth out the action and found several surfaces with very rough tool marks on the hammer, sear, trigger bar and frame that probably account for all the grittyness. I went at the rough components with a sequence of 400, 800, 1000, 2000 sandpaper then also hit the transfer bar and trigger bar frame recess with a dremel and some compound to get that smoothed out too.

Once i get it all back together with the newly smoothed out parts, new springs and some Tetra grease, i cannot believe how much improved this is. What was previously a trigger measured in tonnage and felt like you were dragging a rusty boat anchor though a briar patch now is creep free and very light and smooth though the minimal pretravel with a crisp break at around ~5lb pull. What a difference! :D

Also, i had noticed that the feed ramp was very rough and had a washboard like surface that may have had something to do with some failure to feed issues where rounds were getting hung up in a 3-pt jam. Since i had the polishing materials out, i managed to get that surface smoothed up a bit more so hopefully that helps. All in all, a fun and inexpensive little undertaking with the cost of the gun included. Hopefully this weekend i can test it out and see how much these changes improve the usability of the pistol.

Nice!
I'm afraid I just took the simpler route to smoothe out everything.
Just finished putting it's 800th (give or take a few) round last weekend. Not too bad since I've only had it since November :)

Definitely helped with some of the gritty bits

Good job on the post, JonF. A picture says a thousand words and those were informative.

I sold my last Mak ~a year ago and I kind of miss the caliber. I have been waffleing between picking up a CZ82 and the PA-63...you may have just pushed me off the fence! Nice post!

get the cz82 it's larger than the 63, but a much better firearm in my opinion
more accurate, and more capacity.:cuss:

I did the same Wolff spring swap with mine. It's now a very nice pistol. And, considering that it cost me less than $200 total outlay, I feel safe in saying that it's a fantastic pistol. It's become my regular colder weather carry pistol. Summertime, however, is still ruled by my P3AT.

Maybe you should start a cottage Warsaw Pact trigger job industry?


That's good news, I always am tempted to buy one when I get a CDNN catalog, good to know they can be improved on.

I just got back from the range and have seen definite positive results on all fronts. Polishing the feed ramp eliminated all the ftf issues where the nose was getting hung up immediately as it hit the ramp and not even before it could fully leave the mag. I would experience these hangups 1-2x per mag before the work. Even though this is just a range toy, it was still pretty annoying. +1.

As for the action, I am now able to keep it within a 3" circle at 10 yds! Before polishing things up, I was jerking the gun all over the place with how stiff sa mode was. With da firing, I don't know how the hungarian officers could live to tell any tales. :o +2!

Also wanted to comment on the wolff replacement recoil spring... Its a stiffer unit that is supposed to tame some of the "sting" you feel transmitted through the FEG's lightweight aluminum frame when that steel slide comes slamming back on recoil. It does work and although it doesn't eliminate all of that slap unique to blowback, it no longer hurts after only one box! +3.

Update folks:

I just picked up a digital trigger gauge to measure some of my screw up...err...handiwork and the results on the FEG are nice. I don't have the before numbers but the after numbers are below. Again, both have been substantially improved such that the before numbers would have been atrocious and maybe out of the range of the gauge.

Single action: 7lb 9oz
Double action: 11lb 12oz

Thanks for taking the time to post this information, JonF :)

Did you refinish your slide? It looks bead blasted or parkerized.

I've never tried to 'slick mine up' but thanks for the how-to. I might try the springs first.

No that's the way it came. I specifically ordered one in the "new, test fired" condition from CDNN since it was literally just a couple bucks more than the used models.

I've had two of these lil fun-guns.. the first I traded off and missed it enough to grab another one that was just as nice as the first, maybe better. for $99 bucks (last year from CDNN) it's a steal and has never even burped.

GREAT pics by the way!

Watch out feeding hollowpoints in that gun. They can ding up that aluminum feed ramp pretty quickly. I use truncated cone fmj in mine.

Have fun!
