I have had so much fun with this gun.
The Sig is the exact same gun as the GSG 1911. The Sig/GSG 1911s have tons of add-ons you can purchase to turn them into very respectable target pistols. You can also change out almost all parts with 1911 parts. They do have the non-steel slide, but there are folks on youtube with 20,000 rounds and counting through theirs.
I've attached some images down at the bottom. The first image is my GSG-922 in its original form with some custom b&w ivory grips on it. It is essentially the same as the Sig/GSG 1911 with a shorter barrel.
The slide safety was ambidextrous but I felt it was really flimsy.
I decided to replace it with a steel left side safety and then, after doing some research, I decided that I would just go whole hog, spend more than the gun was worth, and gussy it up just to see if I could do it and learn a thing or two.
I mean, hey, what could possibly go wrong?
As it turned out, I got stuck a couple of times, but after puzzling it over, I made it through and I learned a lot!

My modifications are as follows: Ed Brown steel memory grip safety & thumb safety, steel flat textured mainspring housing & steel magwell, replacement parts kit (very important!!!), ZR Tactical Solutions fitted thread adapter, CW Accessories magazine modifications (converts from 10 to 15 rounds, puts an aluminum baseplate on the bottom to replace the fragile plastic baseplate), new lighter trigger ~ 3-4lb, Les Baer slide stop and custom cocobolo grips along with some Pearce rubber finger groove doohickeys (technical term, really).
The slide safety took a lot of trial and error to get right because I had to file it down to fit properly. I bought some basic jewelry files from Home Depot and used those. The slide stop and thumb safety had to be sanded for a bit as well in order to fit. Mild sanding on the sides of the mainspring housing was necessary. I removed the magazine safety because I didn't want it in there.
The trigger mechanism is Series 80 and I used this link to puzzle my way through it.

I learned a lot and I'm pretty happy with how it shoots now. I wish I could easily replace the front sight, but on the 922 model this is more difficult as it doesn't have standard cuts.
If you were to buy the 1911 model, it would come with more standard cuts in the slide and you can buy custom sights or a very fancy aluminum slide from CW Accessories.
I bought my parts from MidwayUSA mostly and custom parts here:
ZR Tactical Solutions, LLC - Home and here:
CW Accessories LLC | Products
I bought my grips on Etsy from a couple grip-makers on there.
Grabagun had a deal going (not sure if it's still on) for the Sig version for about $300. GSG is going to be in the same ballpark. I might buy another to work on but I think first I'm going to scale up to a .45 for my next project.
The magazines are pricey. The modifications for the magazines are pricey. If you get the improved springs from CW then jams go away. You'll want to oil it well for best operation and consider sanding the paint off the bottom of the slide rails too.
Mine isn't a fan of Winchester 333/555 bulk. Beyond that, it seems to like everything else! It is very accurate, I prefer it for plinking, especially now that it has the steel parts.
If it's a reasonable price and you want a fun gun out of the box, it's all that. If you want to improve it, you can. I think it's a great gun.
