Sig 1911 XO Black Nitron

[LiveLife]

Did a search for Sig 1911 XO but not much came up.

Appreciate any comments on accuracy and feeding of SWC bullets. Looking to use it mostly as a range gun as M&P45 is my night stand gun and G27 travels with me.

Specs:
- All stainless steel frame and slide
- Premium match grade barrel, hammer/sear set and trigger
- Finished in black Nitron
- Novak® contrast sights
- Checkered front strap and mainspring housing
- Single side thumb safety (I am right handed)
- Ergo Grip™ XT Extreme-Use Grips
- Hand-fitted to insure reliability and performance
- Frame and slide are de-horned for comfortable full-size carry

Thanks in advance!

Looks good. I like the list of features. The grips look like they will need to be cleaned of skin after each use.

Why is it, that things I like jump out at me.. like.. while the bill board is shallow cut (good thing) why does Sig put in the horizontal cut line, making it look less like a 1911.. a 1911 slide shoutl be flat. IMHO
why use the softer stainless steel for the frame and slide if it's going to be finished in black? stainless generally dents / scratches easier than a good carbon steel.
Dehorned for easy carry?? with that monster front sight?
OK I'm done.
I like it.

Why stainless you ask? It reduces the number of materials they have to machine. If you chose to not go Nitron, then it is already a rust resistant weapon. If not stainless, you would have to provide bluing or parkerizing finishes or it would rust. I would say that Sig, like most other manufacturers are trending away from carbon steel and bluing in favor of stainless or poly.

Besides, Sig never intended you to use it as a hammer, so the relative softness of the stainless vs. carbon steel wasn't an issue. Also, harder is not always the best choice; tougher is better.

I'm not sure they make it anymore. I believe the TacOps models have replaced them. Honestly don't know how Sig manages their price point for the materials they use. Excellent choice but fewer holster choices. They do have a new line of 1911s coming out that employ more traditional 1911 lines for those who don't care for the look.

Be aware that Sig uses an external extractor on all their 1911s as that is a major factor for some. Reliable, accurate and reasonably priced.

 

[Skylerbone]

Double post.

 

[silversport]

but for the extras...all SiG 1911s are the same...in the Government size, they all use similar parts unless the next model is getting something extra (Novak night sights as opposed to Novak cut Kensite/Champion sights) so you are getting quality...at least my STX is...I have a friend who bought a SiG target and an XO and he says his XO outshoots the more expensive SiG 1911 Target model...so there you go...made in the USA out of good materials...some MiM nowadays but mostly top drawer...

While at the range to do more load testing this morning, looked at several Sig 1911s and the XO Nitron model again.

Really thinking about making the purchase ($849).

Anyone else with first-hand experience as to accuracy and feeding of SWC bullets?

They cut that horizontal line in the slide so it looks like the other Sig models. A good trick to sell a 1911 to a Sig fan. Just for recognition, as if the Billboard wasn't enough.

 

[Skylerbone]

A suggestion: http://www.budsgunshop.com/catalog/product_info.php/cPath/21_28/products_id/74701 for just over $750. Railed and non-railed version are the same price.

I have the one in the picture. Shot it today for the first time. I put 200 rounds of FMJ and Hollowpoint ammo through it without any problems and it is accurate as hell!! I used the 2 factory mags and 3 Colt GI mags. No issues at all. I love it!!

The SIG 1911's are great guns. In their price point is a lot of other good 1911's like SA, a couple Kimbers, and even a few Colts. The Ruger SR1911 is even quite a bit cheaper and is a hell of a gun. You won't go wrong with SIG but there are other viable options available for the same of less money.

Sad thing for me is that I can only buy new pistols that are on the California DOJ approved list. I missed out on buying one of 200 Dan Wesson PM7s made for California earlier this year (It sold as soon as it hit the LGS display case).

I thought about buying a S&W 1911 (enjoyed shooting 686 and currently own M&P 40/45) and there's a used S&W Scandium 1911 for $900, but it has quite a bit of wear.

Over the years, I have shot plenty of Kimbers, Paras, SAs, Colts, etc. and just looking to return back to 1911 platform I started out with 16 years ago along with P226. I have never shot a Sig 1911 but handling several models seemed to show better than average slide to frame fit with smooth slide action and decent trigger.

I know that Sig 1911s deviate from traditional 1911s with external extractor and other features, but that does not bother me as I am looking for an accurate range gun for load testing purposes. And that's the reason for my inquiry into Sig 1911 XO accuracy and feeding of SWC bullets. LGS has both models (without the accessory rail for $849 and with for $879) and found one online for $699 without the rail.

BTW, the new XO models at the LGS now shows the traditional "curved" cut at the front of the slide instead of the straight cut shown on the picture above.

Well, after reading much reviews and comparison impressions, I decided on the TACPAC with railed 1911 Nitron. Why? This will primarily serve as a range gun for load development and accuracy testing. The picture below is from Sig website but the new model I bought has the curved cut forward of the frame. The holster will not fit the pistol with the laser on and that's OK with me. Now I wait the dreaded 10 days CA requires. Will plan on doing some factory FMJ break-in/burnishing of barrel and plated/lead reloads range testing with pictures after the pickup.

1911 Railed kit includes:
1911 Nitron rail pistol
CPL-1 Compact pistol laser
1911 Holster with integrated mag pouch
Two (2) magazines
Speed loader

To answer your SWC question, my Sig GSR feeds everything except SWCs- HOWEVER: I have only used my own reloaded SWC rounds, and I'm an inexperienced reloader. So take it for what it's worth.

Shoot a few hundred rounds through the gun before you make any judgements; Sig made them tight and some break in was required for mine to be reliable.

 

[LiveLife]

Feeding of SWC bullets was one of my primary concern, but looks like many Sig 1911 shooters have resolved the issue with OAL/taper crimp adjustment for most SWC nose profiles.

My MBC 200 gr LSWC rounds loaded to 1.25" OAL will feed well in Kimbers and other tight chambered 1911, but I will start over with the Sig 1911 chamber, which seems to be very tight.

 

[Rail Driver]

The slide looks gorgeous. I love the "sig style" slide on a 1911.. VERY sexy gun. The sights could use a bit of a "melt" and I would love to see it in a bobtail, but otherwise it's a great start for a custom build if you've got the money for something like that.

1911R TACPAC Review - Part 1

While browsing various forum discussions, I found some confusion about this package. TACPAC (Tactical Package) is not to be confused with TACOPS (Tactical Operations) which comes with ambi-safety, mag well, night sights and optional threaded barrel. TACPAC comes with Nitron pistol without the ambi-safety, without the magwell and 3-dot sights. Although TACPAC is "supposed" to come with the Nitron pistol, compare the picture below of TACOPS with my photos and you be the judge.

1911R TACPAC Review - Part 2

OK, here's the initial walk through.

Out of the box, the pistol has a very solid feel (41.6 oz with mag) and due to the Ergo XT grips and checkered front/back straps, there is no slipping or shifting of hands. In line with other Sig 1911s, the safety is small in profile but I did not have any trouble operating it. The slide shows more traditional curved cutout forward of the railed dustcover but still retains the external extractor.

Slide to frame fit is tight yet the slide operates smoothly without any grittiness or snag.

The match trigger comes from the factory at 5 lbs.

1911R TACPAC Review - Part 3

Match grade barrel locks up tight with the bushing. Rifling comes polished with short leade, which required the seating of MBC SWC bullets to 1.245" OAL.

There is hardly any machine/tool marks on the frame or the slide.

1911R TACPAC Review - Part 4

Lowered ejection port with external extractor, sights, magazine and compact laser.

Range report:
Both factory 8 round and Chip McCormick Power Mags were used for three range test sessions. 230 gr FMJ Winchester White Box rounds were initially fired along with plated and lead reloads.

Initial range session with WWB and Berry's plated reloads were uneventful with no FTF/FTE using both types of magazines. The 5 lb trigger had little slack and creep with clean glass-like break. WWB produced 1.5" average shot groups at 10 yards off hand while Berry's 185 gr HBRN reloads produced sub 1" average shot groups at 10 yards (center-to-center).

Since I got this pistol primarily as a range gun for load development, I was eager to test SWC reloads on range test #2 as there was some concern on various forum discussions about feeding of SWC reloads in Sig 1911s. The bullets used were Missouri Bullet 200 gr SWC in both 12 and 18 BHN (Bullseye #1 and IDP #1). My typical SWC loads using the same bullets at 1.25"-1.27" OAL was too long for the short leade barrel. I incrementally decreased the OAL until 1.245" OAL was tested with .471"-.472" taper crimp to freely fall into the chamber with a "plonk" and reliably chamber from the magazine. 5.0 gr of W231/HP-38 was used.

Several hundred rounds of both 12/18 BHN bullets were test fired often with dime/quarter sized holes at 7/10 yards off hand. By range test #3, best 1" shot group at 15 yards (center-to-center).


Summary:
I have Googled to find reviews on the 1911 TACPAC but surprisingly found little in the way of especially feeding/chambering of SWC bullets. For me, the pistol will be used as a test bench for load development and looks like it will fulfill that role quite well. A fellow shooter who has several Kimbers allowed comparison shoot and the Sig 1911 produced comparable (if not better) shot groups using the same reloads.

bds, great follow-up range reports on the Sig 1911R TACPAC!

I recently bought (about 3 weeks ago) the Sig 1911R TACOPS (the non-threaded barrel version). I got to shoot it once. I used the 4 stock mags that it came with. They worked out pretty well, no issues. I still prefer using CMC Power mags with all my steel framed .45ACP 1911s though. I changed my grips out for some black grenade pattern/design G-10 ones made by Larry Davidson. I feel my TACOPS looks and feels better with these G-10 grips on it, than the plastic/synthetic ones that come stock with both the TACPAC and the TACOPS. bds, if you want to see how my TACOPS 1911R looks with Larry's new grips on it, let me know and I'll post some pics in this thread.

 

[LiveLife]

Sure! I am big fan of TACOPS - actually, I am a fan of many other pistols too.

To be honest, I think newer Sig 1911s are very under rated.

Here's Larry's 1911 grips website: http://davidsonknives.com/
and here are a few pics I took 3-4 days ago of my new TACOPS with the new grips:
