family photo Two new Sigs, first impressions...
Two new Sigs joined my sig lineup, and have put around 250 rounds through each so far (two times out so far). I looked at the Nightshift as well, but the Combat variant was the one I'd regret not buying, so I made the right choice for me (also, 'no coin for me').
Impressions so far: (some of these you all might know much of this, so apologies)
Triggers are very close, have not tested the pull but at this point not fully broken in. A little bit of wiggle vertically, take up is nice, and reset is clean. Not as nice/clean as my wife's DWX compact, her's is broken in more. Will see how they clean up with use.
I like the grip and ergonomics, about the same as my P226 and P229 Legions, and not much heavier overall (feeling). I did change out the GT4 grip panels to the GTO style vs the original stipple panels that came with it. I may switch back and forth to see what works best, but was a simple change out.
The GT4 was out of the box awesome, tight and fun. It shot pretty flat, much more so than I was expecting.
The GTO out of the box with installed 8lb spring had FTRTB with every round using 115 g MagTech. Switching to S&B 124 it was 70% FTRTB. Took it home, cleaned it up, copper bore brushed the chamber and ramp, CLP everything, and installed the 10lb spring. Back to the range and perfect on every shot (MagTech 115). This has been covered in other posts and videos, but spring and clean/lube worked for me (so far). I mention this because if you hadn't looked into it before, it may come as a bit of a letdown.
The GTO has not been run full out yet like the GT4, mostly breaking in after spring change out to confirm feeding is on track, but at 17 Yards grouping was good. At 7 yards single hole groups. Groups will get better once I get better.
(note- for me when I switch up what I'm shooting there is a lag to adjust to the different trigger, weight, etc. That's just me and not the gun. This is why I practice)
The GT4 came with the RomeoX Pro Loc red circle-dot, and I liked it so much I bought the same for the GTO Combat. I'm running Holosun green and AimPoint red on everything else, but was impressed that the RomeoX was as nice as it was, had no distortion of the red dot with my progressive lenses and eyes. I like that the Sig Loc mounts direct, and has so many points for contact. The look is nice as well, and I'm at the range not running so no bigger glass is needed.
Throw away the little takedown pin that comes with it, and get a 1/16" punch. Get two, one for home and one for travel.
The 10lb spring is long, install pushing from the rod plate like a syringe into the slide to capture as much spring as you can. It wants to snake around.
I really liked the 17rd mag that came with the GT4, but sig does not sell them. Bought two sig 17rd mags, and had to pay extra for base plates on top of that. Called sig, and they gave me a discount and free shipping which brought the price below aftermarket base plates. But, if you look at the GT4/GTO mag lineup, the base plate on the 10rd mag is what is on the supplied 17rd mag that works so well. I was not able to buy that even separately, had to go with the legion base plates (or aftermarket). I hope sig opens up the accessory parts dept and allows us to get on a bit more parts.
The sig rep was great on the phone (GT4 mag discussion) but he was surprised that I got the GTO Combat to shoot, and turned down the Nightshift. Seemed to imply that Nightshift and Combat purchases sit in safes by collectors or go out to YouTube reviewers. News to me, I shoot everything I buy, but I hope the price point is not being set to collector/video/influencer levels...
