It's hard to screw up a polymer frame striker fired pistol.
Pretty much everything over $300 MSRP will be a very reliable and long lasting handgun. It's looking like sig USA designed polymer framed handguns just don't work right though.
I wanted to like sigs so bad, but the p250 fiasco combined with seemingly thousands of different finishes they made available from the 2008 - 2016 era and still under the same CEO that destroyed Kimber's reputation put them in the bottom of the list. I'd jump on older p series, and the sig pro however.
Also that sig won recent contracts and immediately bought back thousands of M17s after delivery then resold them to civ market was strange. I looked at a few contest requirements for different contracts and it seems like someone had a spec sheet for the p320 and other sig firearms in front of them while they wrote up the requirements.
I can swear I once saw a specific paint color called out that was an exclusive color just for sigs, and nominal dimensional requirements matched exactly.
As far as German made arms go, I tend to stick with Heckler & Koch. I've had my USP .40 for over 20 years, put between 25-30K rounds through it, and have had a total of 3 feed jams that were easily cleared. The MP5 & G3 are both magnificent weapons as well.
While I prefer the feel & stopping power of my SA 1911, no sidearm has come close to the USP reliability wise.
It is disappointing what Sig has become. In the late 90s-early 000s the name was unimpeachable; pretty much unanimously revered by shootists. The reputation free fall is a shame, but well deserved.
