SIG 220 trigger pull


April 24, 2003, 08:04 PM
I've got an older SIG 220 thats a great gun. However, the initial double action trigger pull has got to be one of the heaviest and grittiest of any double action auto I've used including other SIGs.

What kind of simple steps can be used to improve it (spring changes, etc.) Barring that, who is a good reliable smith for SIGs?

Does anyone have instructions to detail strip this gun?

I replaced the origional trigger with a short trigger from the factory. This really helped with the trigger pull on my 220, but that is probably due to the better reach.
The instructions that I used to detail strip my 220 to replace the trigger came from the book "The Gun Digest Book of Firearms Assembly/Disassembly Part 1: Automatic Pistols 2nd Edition" by J.B. Wood. The instructions are listed as the Browning BDA 45.
Some gunsmiths who advertise work on Sigs are: Mark Graham of Arizona Response Systems; TJ's in Ca.; and Novaks.
I believe Teddy Jacobson also works on Sig pistols.

Send it in to a good Sig-smith for a trigger-tuning & reliability job.

Teddy Jacobsen comes to mind.

You could send it in to SIG Arms, thye'll do a trigger job on it for about $60 and the work will be covered under warranty.:cool:

As Sig DA triggers are one of the very best in autos, I would really take a long look at what might be wrong with your gun before you spend money on it.

It would be a shame to spend $100 when all you needed to do was remove some sand.

Check out the "Assembly/Disassemby" series of books. There is one book that is just autopistols. The Sig Classics were listed under "Browning BDA .45". Much clearer than that PDF manual.

Over the years I've found that there is a HUGE amount of variation in Sig's triggers.

I've dry fired, and live fired, many new and used Sigs at gunshows and matches, and have always been rather shocked that some of the triggers are simply as bad -- heavy, gritty, stagy -- as they are.

A few years ago I was looking at new 220s, seriously contemplating purchasing one. The first one I picked up had a so-so trigger. The next one had a HORRIBLE trigger, as did the third one at another dealer.

Yet another dealer had one with a so-so trigger, but the other one on his table had one of the finest double action triggers I've ever felt. It was smooth, even, and relatively light.

Unfortunately, his prices were almost $100 more than what the other dealers were charging for Sigs, so I didn't get the 220, and still haven't gotten one.

Some time later I helped a friend purchase a 228. We went through dozens of 228s at the Bealton show, and again found a HUGE variation on the Sig triggers.

He finally ended up with a lightly used gun for a very good price with a so-so trigger.

I never fail to play with the triggers on the Sigs at the gun shows I'm at, and the same holds true. It seems to break out that about 1/3rd of them are good, 1/3rd are so-so, and 1/3rd of them never should have left the factory with the trigger action they have.

I found that my 226 trigger was gritty due to junk getting into the trigger and hammer assembly. I cleaned it as well as possible and worked a liberal amount of RemOil into the mechanism. Its definitely much better.

The way to tell that is that if you can hear an audible creak while pulling the trigger it needs to be cleaned.

My experience is the same as "Mike Irwin" with regard to Sig Triggers. And I am glad to finally see someone admit this in public as I usually only see "Sig is the Holy Grail of DA triggers" type of response.

Thanks Mike.

I hand picked a P220 with the best DA in the store, but it was still tougher than my friend's home market/PX gun. So I sent it to Teddy Jacobson (Actions by T) who improved it a lot. It is now lighter and smoother than my friend's but not so much so that he was interested in paying for the same gunsmithing on his nice stock gun.

I have heard of some nice work from Sigarms and some just minor touchup. I suspect it depends on their workload, who gets the job, and how effectively you complained. Teddy charges but he apparently always does good work.

I can still hit better DA-SA for IDPA SSP with my tuned CZ75, though. At close range the difference is small and I consider the P220 a better weapon; bigger caliber, 100% reliable and with night sights.

I had purchased a 220 a few years ago based only on the reputation they have for their triggers. The sample I bought had a 17+ pound DA trigger (ran out of weight on the scale) & a 9 pound SA pull. It was also very mushy & vague in its pull. After a 12 week visit to the factory & 3000+ rounds, I sold it. The many problems that gun had never were fixed & I haven't bought another SIG since even tho (with all the fans they have earned) I know they probably make a quality product.

I guess I've been lucky. All the M11s I've fired and the 225 I bought sight unseen have been really nice.

I wonder what causes such irregularity in a gun so precise and simple?

Thanks for everyones help. I went to Mr Jacobsen's web page I don't mind the price of admission so much for a job well done, however, the shipping back and forth will be about $80 and thats the killer.

Anyway I detail stripped the gun cleaned everything real well then relubed with Militec 1 and some of their grease. The DA pull is still heavier than I like, but at least its smoother. I'll probably go to a Wolff main spring and see how that works.

Other than the initial double action trigger pull this gun is everything a SIG is supposed to be, superior accuracy and reliability. The single action pull is great.

Actually this gun is so good in other respects that the poor DA pull is tolerable. On the other hand my SIG 239 has the best DA trigger of any DA auto that I have used. Sometimes you just get lucky.
