Last year, Colt did a small run (I've heard 100 to 130) of Government length Rail Guns. They were black-nitrided stainless steel, with 100% tool-steel parts, 20 LPI checkering done by Pete Single, and a flush-cut and reverse-crowned NM barrel, EGW bushing and recoil spring plug, and Novak thumb safety and sights, all full Custom Shop builds with archive paperwork and test target. I was able to snag one before all the reasonably-priced ones sold. Google the model number "O1070rgz" if you want to see the full spec sheet.

Well, it looks like Colt just released a Commander version of the same pistol. Bud's has the model listed on their website if anybody's interested. There's also one listed on GunBroker for about $250 more the last time that I checked. I already reserved one to go with my Government-length RGZ.

No relation with either Colt or Bud's. I'm just a big fan of these models and wanted to give fellow ARFCOMers a chance to get one while they last.

Anyone know where one of these "O1070rgz" models can be found?

Good luck finding one of the Government-length O1070RGZ models now. There were only 100 made last year and the vast majority seem to have been sold. Your best bet is to keep checking GunBroker.

ETA: I found two O1070RGZ listings on GunBroker just now by searching for "colt custom rail gun". Both are at least $500 higher than they were selling for last year, but that's supply and demand for you.

Is the extra cost of this pistol worth it over the currently available Combat Unit Rail gun?

The Combat Unit is a production line pistol and are fitted/assembled as such. The director of Colt's Custom Shop said this about the O1070RGZ on 1911forum:



Whether or not that's worth the extra cash is up to you. To me, it is. I've compared it to my friend's Ed Brown Special Forces, and while I'd be happy with either, I prefer the RGZ.
