Reduced trigger pull on Sig P239

[wacky_doug]

I asked this question on SigForum, but I'll ask it here too.

I'd like to reduce the DA trigger pull on my P239. But it's a carry gun, and so I obviously need reliability. I've got a Wolff hammer spring pack. Wolff says 18lb is factory standard, and the pack includes 12, 14, and 16 lb springs. What's the lowest I should go?

Alternatively (and much more expensive), has anyone had the Sig Shop or GrayGuns do a trigger job on their P239?

I am considering going DAK, too.

18 lbs seems really high. The factory web site say 10 lbs. see

I have three sigs now all with newish factory trigger springs. I'm no expert in trigger pull weights but they never seemed overly hard to me. Why mess with perfection? I'd start with sig factory springs and go from there.

IIRC the "one step down from stock" springs usually end up being reliable. You may want to change them faster, though. Always range test a mainspring change.

IMHO on newer P series pistols the DA really isn't the problem... it's the unusually hard breaking single action sears found in most of them today. A good gunsmith can often clean up the SA considerably, which is where you will see the biggest benefit. A lot of the newer P series guns I've handled seem to have SA pull weights likely northward of 5 pounds, which is bad. The SA breaks so hard in these pistols I have a difficult time not smashing the trigger into oblivion, which causes the muzzle to wander. The weird part is, of course, this seems to vary from lot to lot. Some of them are OK and others feel like you are hitting a brick wall with your trigger finger. This is bad because it is difficult to pace your trigger pull so that you will not overpull/smash the trigger
in SA mode.

Don't even bother with DAK. It's a neat idea in principle but in practice it actually kinda sucks, unless your thing is shooting DAO handguns with long trigger resets. It's like a crappy version of the HK LEM trigger- light DA pull, but it's crappy in the sense that the panic reset on the DAK is actually a heavier pull than a full reset. This makes no sense at all. Sig probably would have done what HK did, but they were probably afraid of getting sued so they made it
work differently.

10lbs is the trigger pull. 18lbs is the hammer spring, which contributes to the trigger pull weight.

Thanks, I definitely won't go more than 1 step down. Just wondering if anyone else has tried this combination.

Any idea how frequently a hammer spring should be swapped out? This gun doesn't see as much range time as my others, although it gets more dry fire practice.

SA break doesn't feel as bad to me on this one. But there are definitely differences between my various p-series guns. I'd really like to learn how to smith these myself. I'm pretty handy with stuff like this. Perhaps I'll have to take a class.

Damn, I didn't think about the long trigger reset aspect, and didn't even realize about the panic reset. I stumbled into a set of lightly used DAK conversion parts on another board for probably 1/3 the TGS price. I just haven't committed to swapping stuff out just to feel the difference. And no, I'm not a wheel gunner.

One of my favorite triggers is the P7M13. It's like buttah.
