32 Guardian Trigger Pull.

[dlstanf2]

Seems as though these little 32s don't get enough love. I just bought 2. One for myself and one for my sister. Lightened the hammer spring enough to have a really reasonable trigger pull. Hope it's not to light to pop the primers. I just bought a new set of the Hogue groups. Will be here in a couple of days. Then I'll head back to the range for target practice. Just hate burning ammo. Managed to get a few boxes in the $18 - $22 range.

I have two of them, too; good choice ! ...... ....but both are all mine......

They supposedly leave the factory with ten pound pulls. Mine seemed to lighten some in the first 200 rounds, not much change after that, maybe smoother. Now just a bit stiffer than my .22 SP101 which has checked seven pounds, so I'll call the Guardians at eight pounds. How did you lighten the pulls?

Burning ammo is brave these days. I haven't seen a box since June, but I was already well-stocked. .32 Auto is a very under-rated round, I think. Both it and .380 have pluses and minuses, but for me .32 is better overall.

I had two. I bought the second one on consignment. It has been melted & stippled on the front of the grip. I don't know why the seller sold it so cheap. Maybe she was told it was worth less because of the sights being taken off or maybe she sold it out of spite. (I saw the copy of her driver's license so I know it was a woman.) I got the pistol with $125 worth of work done on it for $175 + the Kalifornia fees. I later sold my first one for more than I had paid for it. It did have a problem that the hammer would not snap when you pulled the trigger. It would just go back & forth. I was able to compare the two pistols & found a spring that was out of position. It wasn't easy but when I got it positioned correctly the hammer functioned perfectly.
I would be concerned about lightening the mainspring.

Love my 32acp Guardian.  After I purchased mine, I immediately sent it to NAA repairs, to lighten the trigger pull, and also for ejection problems. 

Even though I had to pay shipping back & forth, I have no regrets.  No charge for service.  Now I have a little 32 that is absolutely perfect, imho. 

The trigger pull is still a little stiff, but for safety reasons, I think it's perfect.  Definitely a lighter trigger pull.  No idea what the "poundage" is.   Oh, and no ejection problems.

NAA was impressive to deal with.

I experimented with my Guardian to try and successfully reduce the pull

I actually machined a new hammer spring seat and removed .010" at a time to lower the spring tension. With each cut I would test the pull and also fire five primed cases(no powder or projectile). I only got to about a two pound reduction before reliability started to suffer and would light strike 50% of the time. That was with Winchester primers. With CCI it was 100% fail to ignite and required two or sometimes three pulls to fire. Sacrificing reliability wasn't worth the negligible reduction in pull so I left it stock and will patiently wait for it to naturally drop with use.

To lighten the trigger, remove the trigger spring and sand it down with a stone, I used a diamond stone, along the length of the spring while rotating the spring. Dont changed the length or shorten the spring. You just thin the spring some, not much. Unless you can find a spring with the same coil length and a slightly smaller wire diameter. You must watch the firing pin indentation of the primer. You dont want a light primer strike. My wife has weak hands and cannot pull the heavy trigger.

I had a 357 magnum with a heavy DA trigger pull. This was the normal for a LE firearm. I had the trigger lightened by a gunsmith. They used the same method 30 years ago. They filed the spring and it was not very uniformed.

BUT, BIG BUT,, A HEAVY TRIGGER PULL IS FOR YOUR SAFETY AND SAFETY OF OTHERS. IF YOU DON'T KNOW WHAT YOU ARE DOING THEN USE A GUNSMITH AND BY ALL MEANS EXERCISE CAUTION.

After going to the range my lightened trigger spring began misfiring. I had removed too much material.

So I began some spring testing. A new spring has an outer diameter of .280 in. The one that was too light had a diameter of .275 in. The one I ended up with a lightened pull and good primer strikes was .280 in.

I did not have a way to measure compression. But, compression & rebound are both affected.

With a reduced trigger pull some European ammo will not fire. I always suspected that small pistol primers in Europe might have harder cups for submachine gun use. Even with stock factory springs I had regular light strikes on S&B .32ACP in my Guardian in particular. GECO and older Fiocchi had occasional light strikes. With today's ammo shortages I'd leave things alone unless I had a good supply of ammo with proven reliability. I ended up polishing contact surfaces and leaving the springs alone.

Assuming that ammo is a definite factor, I use Aguila .32 Auto, 71 gr FMJ. It is by default, as it is normally the only .32 Auto in good availability in my area. I've had zero issues with it in about 500 rounds, beyond a few expected hiccups when the guns were brand spanky new.

Remington FMJ works well too. It should, since they built what is now Aguila's factory.
