Yesterday in a gun store I was looking over a new Sig P220. In general I liked it, but the single-action trigger pull of that gun was terrible. I've never owned or shot a Sig. Is this typical of the P220? Is it fixable?

My P220 has a good trigger pull both S/A & D/A.

Mine are good but I dry fire a lot and that smooth's them out. There is an after market trigger offered by Grayguns that offer a couple of options.

I own two Sig P220's and the triggers are great on both. Everything is stock; no light springs, etc.

I've had many Sigs, and never had anything but excellent single action trigger pulls on them. My reason for being off Sigs nowadays has to do with the high bore axis, which is something you may want to consider. Despite poo-pooing by the Sig fan-boys, it will increase felt "muzzle flip" in the recoil impulse, which makes follow up shots a bit slower, particularly in a P220, due to the harder recoiling of the .45 ACP.

Here's a discussion of the subject.

That's funny, since I get very little muzzle flip with my P220.

It's just physics. You choose not to notice it because you're a fan boy, LOL.

What's the real-world difference? What fraction of a second did you actually lose shooting a 220 side-by-side against a G21?
Thought so..........

Just a perceived difference that's quite noticeable. I assume that the perceived difference would also register in a timed test, but haven't conducted an experiment. The laws of physics inform us that it should be a measurable effect, however.

I have......with several calibers.

I (stress on "I") was faster and more accurate with the Sig equivalent (in the .40, the M&P). Now, that's likely due to the amount of time I spend shooting a Sig vs anything else. The "outlier" .40 is, in all honesty, due to that M&P not being "stock" That speaks to my comment, though:
The physics are what they are, but are only one variable in 'the whole". The "high bore axis" argument is irrelevant to, at best, a small percentage of shooters. The "average" shooter (if 'they' exist) has a plethora of real world issues to overcome before bore axis is even a blip on the radar.

I noticed I didn't shoot traditional Sigs very well long before I had a theory as to why. Once I developed skill with Glocks, that I couldn't develop to nearly the same degree with Sigs, I began to discover that there is a scientific explanation for it, and it made sense. After getting pretty good with a Glock, I could easily perceive, upon shooting a Sig, exactly why I don't shoot them as well. It's the difference in perceived muzzle flip.

My 220 has an excellent DA/SA trigger. It is factory stock. I recently shot another 220 that was lousy both ways compared to mine. And then I have a 226 that has had work done to it that feels like a really great Colt Python. Sounds like the 220 you handled would need some attention from a good trigger 'smith.

I have a stock P220 SAO in 45 and 22LR. Decent trigger pull. Not a glass rod trigger break.I suspect a trigger job would improve it

A low bore axis will make a pistol shoot much better. You can't deny physics.

Sigs are definitly not for the limp wristed. It's a man's pistol.

Looking at all the posts this seems to sum everything up.

Compared to the single action trigger pulls on my Beretta 92 & 96, I'd say the stock Beretta is better. But neither are a 45 ACP firing gun

The best trigger i ever felt on a Sig like pistol was the Spinx? (Swiss) don't even know if that pistol is made anymore, I haven't seen them in about two decades.

my gun is the European release and it said browning on 1 side and sig on the other. it is high polish blue as well. it was called a B D A 45 the trigger is nice on single and better than average on double.
