I purchased a Sig P6/225 a few months back and have put probably 600 rounds through it so far (I know I wish I had more time to shoot :() and I absolutely love it. Its a great little 9mm that hasnt had one hiccup yet! The only thing that is less than desirable is the sights. It has the factory all black sights and I cant shoot with them at all. I have shot numerous other guns with white dot sights or night sights and I get on target faster and I am able to aim better.

My gun came with #6 rear and #8 front sights. I have done some searching and have found that most 9mm sigs come with #8 sights both F and R. I dont necessarily care to spend $100 or so on night sights so I was hoping to find some Sig factory "line and dot" sights to replace mine. I can get a Gunsmith's set of factory sights cheap like this here. (http://www.cdnninvestments.com/sig8sisetgus.html) If I use this kit I would probably have to step the front sight down to a 7 and the rear down to a 7 also. Would this mess up my POI? How do the numbers work? If this isnt a good option, what are some options for me?

Thanks in advance.

Also, is there a spring available to lighten the double action trigger pull? If so can someone post a link to what spring I need?

With Sig sights, the higher the number, the higher the point of impact (POI) will be.

At 25 yards:

Rear sights move POI up ~2" with each increase in number.

Front sights will move POI up ~1" for each number higher.

So if you went with a #7 front and a #7 rear, you would raise POI by 1" at 25 yards.

CDNN has a ver limited supply of sight numbers, if you can't find what you need, I might be able to help you. I was going to sell all my Sig acsessories in one lump (layed off, had to sell), but if you need a particular sight number, PM me.

New ones can be found at Midway or the Sig store, but they are rediculously expensive.

You need to replace the hammer spring to get a lighter release ,it's on the hammer strut .Most surplus P6s came with a 28 lb spring to prevent an unintentional discharge , I replaced mine with a 19 lb Wolff spring I also have an extra 18 lb spring if you're interested .

How much did the DA trigger pull get better with the lighter spring? Is it too light now? Does this affect the SA shots?

I am interested in the spring. PM me with a price if you want to get rid of your spring though.

I got sights for my P239 from Top Gun Supply. I think they have plenty to order from.

Also, is there a spring available to lighten the double action trigger pull? If so can someone post a link to what spring I need?Commercial P225s came with a 24lb spring. The German P6s were uprated to a 28lb spring. This is a link (http://www.topgunsupply.com/wolff-hammer-spring-sigp220-225-226-228-229.html) to the stock 24lb spring; it lightens the DA pull to that of a stock P229 but doesn't have issues lighting off hard primers. You can drop down to a 20lb or less hammer spring if you want, but I would not do so unless you intend for the pistol to be used solely as a range toy.

TopGunSupply also has lots of different sight options for your pistol. I have been perfectly happy with a dot of white epoxy paint on the front blade of my P6s, but then again I'm known to be cheap. :)
