The last time that I was at the range qualifying, a couple of co-workers had new 1911’s with them. One was a SIG 1911 (don’t remember the model) that ran very well. The other was a Kimber “SIS” that couldn’t get through a mag without a problem.
Here’s a post I put on 1911forum.com
Since then, I’ve noticed that the frame underhang under the slide is common, as it is present on two other Sig 1911’s that are at the shop. I’ve put around 150 rounds through it so far, with only 1 doublefeed when my buddy was shooting it (possible user error).
Thus far I’ve disabled the S80 slide & frame parts, planning to fit a standard 1911 slide with internal extractor as a project. I figure the cost of getting slide serrations cut & refinished is around the same price as a new slide, so might as well try it out.
Thus far on the pistol:
Fusion .120 chamfered bushing & thick flange
Fusion magwell
STI Aluminum trigger
XP firing pin spring
TJ customs S80 disable plate
EGW FPS
Painted front
Getting:
10-8/Warren blacked out rears
VZ aliens / dirty olive
Ambi safety
My .45 dies are coming in tomorrow, so I will definitely be putting this thing through a few hundred rounds. Will post results.
I had a SIG 1911, shot around 3,000 rounds through it before I decided that I wanted to consolidate all my pistols to 9mm. I never experienced any problems with it, and it actually had a better trigger than another ‘name brand’ $1,700 1911 I was shooting. I shot the hell out of it at Vickers classes (he said nothing about it one way or the other), and it held up fine. Would I get another? No. I liked it but there are as good or better 1911s around the same price. Would I have an issue having another? Not if it was the one I had. Like most everything SIG nowadays there are too many hits-and-misses with QC, and their guns are like Forest Gump’s famous box of chocolates.
If I was going to buy a mid-range production 1911 (e.g. nicer than an RIA, not as nice as say a Springfield TRP) right now, I would look very hard at Smith and Wesson or Springfield’s offerings.
I’ve got a Rev 2-Tone TTT that I just started shooting. I’ve got about 100 rounds through it including some lightly loaded 200gr SWC BE rounds. Thus far I haven’t have any functioning issues. Fit and finish are good, and with the exception of the unique slide profile and external extractor all the parts are standard 1911.
The SIG forum is full of doom and gloom about the newer US made pistols, but there seem to be few actual complaints compared to the amount of people bitching that they’ll never buy a new SIG. I also have a P220R Sport that’s hasn’t had any issues aside from not liking Blazer aluminum ammo. Anyone can build a bad gun. If I stayed away from every company that had bad press on an internet forum, I’d never own a gun.
I’ve got a Sig GSR in a commander slide. Nitron finish. I’ve got about 700 rounds through it. I do get the occasional out of battery (feeds the next round, but slide does not go back fully into battery), especially if it feeds low powered ammo like WWB or Fiocchi. I like way the gun shoots. It’s dead accurate at the 25 yrd line. The stock trigger is very crisp, with no creep. I’ve yet to have issues with the external extractor. I may do some research and buy a new heavier recoil spring to see if that fixes the out of battery issues.
If I did (read Marylander 
) carry, the Sig would be one of the last guns I’d choose. If I want to go to the range and plink at a 25 yrd bull, I would definitely take it along.
I had already ordered a Scorpion a while back and have been waiting for a while now for it to arrive. Thanks god I seen this thread and had time to cancel my order with the dealer. Went up there this morning to look at a STI Trojan and the “E” series Smith’s and ended up walking out with a Colt “80” series MK IV Government model 1911 that was used with 7 mags. Think I will be good for now until my dealer starts carrying the Les Baer’s and Ed Brown’s.
Might want to send it back to Sig. My gun would also fail to feed weak WWB rounds, but worked well with the hotter Blazer .45ACP. Once I sent it back and they replaced the extractor, it functioned a lot better with cheap WWB.
My Sig 1911 is also dead accurate–but I think that’s true of the 1911 series in general. Did a clover leaf with it at 25 yards.

Sig have a reputation of producing quality pistol, but may take on the subject matter if you are really interested in getting a good reliable 1911 go get a Les Baer, Wilson and if those brand are beyond your budget then Springfield and you’ll not regret it.
This. Far too many quality 1911’s in the price range to add the above who decided to jump on the 1911 bandwagon.
Again if I have to purchased a 9mm pistol then Sig P226 is my #1 choice bar-none, but 1911 I don’t care how nice they look feel or shoot it will be my last choice. By the way I have a P226 classic mid 80’s production, has already almost 25,000 rds factory load ammo down the pipe and the next malfunction will be the first, that’s what I call reliability in the highest regard.
I know this thread is a little out dated, but I have basically the same question, with a twist. Would everyone agree that if the price of the Sig was roughly 30% cheaper would the hesitation to purchase one still exist knowing that the money saved would be spent increasing the performance and reliability where possible? Hopefully bringing the Sig on par with the other options mentioned. Needless to say I like Sigs but respect others opinions and prefer to learn form others first. If you would still stay away from the Sigs where would you start to look for a good base Thanks as usual for your advice…
We quit stocking/selling Sig 1911s because over 90% had to go back to Sig to make them work. Some multiple times.
Well that pretty much sums that up, thank you for your time…
I put about 100 rounds down my friends GSR. It shot well, I thought it was a very good feeling gun. I couldint shoot it very well due to the XS big dot sights and i never shot before.
While one data point does not make a line, here is one more data point:
SIG 1911 “Target.”
Box “DATE” tag is “15-Dec-2010.”
Round count so far is 1,000 - 1,200.
Per outing round count: usually 80-120. Gun was detail stripped, cleaned, and lubed on acquisition; has only been field stripped and cleaned since.
All rounds have been full power ball handloads (Win. 230 gr. bulk FMJ; 6.3 grains Unique; CCI LP; mixed commercial brass).
Six magazines: 2 SIG originals; 2 SIG after buys; 2 CMcKs.
While this is the “Target” model, all shooting has been action type drills, including some 16 rounds in under 10 seconds.
Results so far: not a single failure. Gun is tight (have to back the slide back, Commander-style, in order to twist the buffer with fingers). Best 1911 trigger I’ve ever experienced. Accurate (if I take my time, I can nail old shotgun shells at 10-30 yards).
Would I trust this pistol? You bet.
meh… Ron
10-8/Hilton Yam have one in their possession for eval. It will be interesting to see what he has to say.
I’ve had nothing but problems with my Sig TacOps carry. I bought it to run a suppressor for HD but out of the box the gun would not even run itself, let alone a suppressor. Did the basics at first; polished the ramp and breach face but still ran like crap. Then found a large burr on the barrel link lug that was actually catching the barrel link; cut that off but still ran like crap. Disconnector was catching on the slide very hard so fixed that. Polished and blended alot of the internals, installed a 17 lbs main spring and installed a Wolff variable power spring. Finally got the thing running and thought I had it fixed but now it wants to throw brass at my face so a new EGW extractor will be on the way. Just trying to get the thing to run properly so I don’t pass it on to some other unexpecting soul. Its a great looking gun, too bad it was not intended to be a safe or range queen. The price of the Sigs is intriguing for the features you get but the performance is not there IMO.
Springfield and Colt.
