There's 2 generations of the 2022....what's the difference in the 2?
There are way more than 2 versions of the SP2022. As 9mmepiphany pointed out the orginal gun was commissioned for a French LE contract. They plan to keep them in service until 2022. They modified the SP2009.
The orginal guns shipped to the French were made in Germany. They had triple serial numbers and German proof marks. Contract overruns made their way into the US in small black boxes with 3 mags a medium and large grip. The gun came with Siglite night sights installed. These guns had the Ifalon finish which is shinny and have an internal extractor and external laynard loop. These sold for around $400.
There were also a lot of triple serial number guns that did not have the proof marks. It is not clear if these were assembled here or in Germany. I have read both. The parts are definately German but the finally assembly may have been here in the US which is why there are no proofmarks. These still came in the small black boxes with 3 mags etc....
All of these guns were being bought up by smart dealers and sold for a decent price. Sig realized that ther was a market for the SP2022. I think this had a lot to do with price point and the fact the P250 stumbled out of the gate.
They then brought production to Exter, NH. They now make all the parts here including barrel and frame. They changed the extractor to an external one in order to capture economy of scale with existing Exter production. They also got rid of the multiple grips and started to ship with a new small slim/E2 type grips with an internal laynard loop. The slide finish is now nitron like all other US production Sigs. The also changed some of the small parts to MIM and the standard model ships with contrast sights and 1 mag. They are selling the mags for $40 a pop which is where they are making their money back on these budget guns. These basic guns sell for about $385 give or take a few $$.
There are also reports of Frankenguns which are parts guns mixing and matching parts from various runs of these pistols which muddy the waters. Most of these were produced here with a mix of German parts and US parts before the US production was fully up and running.
From most accounts the 9mms from both sides of the Atlantic are great guns. There were some early reports of issues with the 40S&W and .357 Sig US versions but the buying public, beta testers, have helped Sig work out those bugs.
The triple serialed German proofed guns are the most sought after. These will sell for about $500 in NIB or LINB condition. Then comes the triple serial numbers without proof marks which will still get you close to $500 used and then the new guns.
They are one of the better values in combat sized/duty sized polys on the market. I own one in 9mm and love it. It is a great truck gun budget house gun IMHO.
