SIG 220 DAO experiment

After finally buying a 220 in 1997 I had the factory convert it to DAO, which merely required changing the hammer and deleting decocker parts. I theorized that since I was principally a DA revolver person there would be some advantages to this. I reconfigured the trigger to a BHP-like profile, and had SIG do their standard action job. After two years I had to admit that in my case I shoot the standard version considerably better--not as well as my revolver but well enough and much better than the DAO system. I was also able to examine the surfaces that SIG stoned and smooth them further (I am a SIG certified armorer), which resulted in very nice, improved DA and SA. I doubt that I will ever stray very far from my .357 revolver, but the SIG has evolved into a very nice gun, too. It is still uncannily quick from the holster and a very fine pointer--probably the quickest gun I own in that respect.I can't figure out quite how they managed to design that into it so well, but they did. This info may be of some help to those wondering about the DAO option. It was 'educational' to me.

I'm like you Robert. I still shoot revolvers (DA) better than I do DA/SA pistols. Blame it on 10 years of revolver as a duty weapon.
 
Excellent thread which begs the question -- which revolver do you two men put so much faith in, with what loads, and why? Are we talking recreational shooting, or a gun you intend to use for carry and self defense, or both?

Reason I ask is that I love to shoot full size 1911s, and the Colt Trooper Mark III, but I find both too big for a CCW weapon. I am still in my quest for the most suitable CCW for me... I often think of switching to a S&W M65 or a 3 inch Ruger GP100... but there is a lot of weight and bulk there for CCW...

A DAO Sig, Ruger SP101, or S&W M640 have been on my mind a lot lately. Thanks
 
Robert,

I own a P220 DA/SA, use to be my duty weapon and love it. I will be using it this year for PPC and IDPA.

I have a P229 DAO on order (since Dec. '99). So, my question is this, did Sigarms do your trigger job and if so what is the new trigger weight? What was the turn around time (4 months and no gun....have mags, but no gun)?

Thanks
 
FWIW, my main revolver is a 4" Ruger Security Six, originally light barrelled, now a HB, and successor to a 4" light/heavy barrelled Service Six. Started using these in 1981 for (plainclothes) duty when I had to give up my LW .45 ACP Commander, and took up firearms instructor duties as well. Went through vast quantities of w/c, 110 gr .38 Spl plus P plus, 110 gr Magnum and 125 gr Magnum ammo which required periodic replacement of barrels from forcing cone washout. The guns themselves never gave a moment's trouble but the spitting eventually became a nuisance in each case. Std. duty gun at that time was the 3" Speed Six .357 and they were durable as a ball bearing. I have a very nice 4" GP but it is a big gun and not suited for CCW; I think discontinuing the 'Six' series was a mistake. The last and best load was the 125 gr JHP which I still favor. I could still be very happy with a 3-4" K frame or 'Six' series gun in a Sparks #200AW holster.

As to the SIG DAO, turnaround was about a month. Never weighed the DA but would guess it around 12#. It was smoother upon return but having examined the areas they worked on I think spending a little more time would have been in order.

With almost 20 years invested in DA revolver work I doubt I could ever shoot better with another type of weapon; but 20 years' work with the 220 might produce some very good results, too. Oh, well--it's fun.
