I've taken mine out to the range a couple times and I've put about 150 rounds through it.
I have an injured/weak right hand and arm -- I really can barely grip with my right hand -- so my accuracy testing is pretty subjective. It is quite accurate and easy to shoot.
Reliabiity is probably good. I had one malfunction, a failure to extract, on the very first round that I attribute to easing the slide forward. On Sunday I shot 7 rounds of PPU Serbian stuff that I bought in the 2009 shortage and the gun would not eject the cases. It felt noticeably under-powered, so I'm chalking it up to the Serbian ammo.
It ran just fine on Blazer Brass, Fiocchi 95 grain and about 10 rounds of critical defense. The Blazer brass seemed to be less powerful than the Fiocchi ammo, but the gun still ran fine. I haven't bought 380 for awhile, so I'm sort of scraping up the leftovers from when I used to shoot them more. The gun is not as finicky as the SIG 290RS 380 that I used to have. And, it is much more pleasant to shoot than the old LCP (and way easier to manipulate and clear issues). It's obviously not as "EZ" as a Shield EZ (which are really easy to shoot) but it is a much smaller gun.
The gun has a pretty tight lock up, so for me it is actually pretty difficult to rack. I did put a Arachnigrips slide spider on it, which made it much easier to manipulate.

Trigger pull weight on mine seems to be about high 5 pounds to 6 pounds, but it seems fine. It definitely breaks further out than my M&P triggers, so that is just something to watch for. I prefer that weight (one of the reasons I don't have an EZ) so it is fine with me.
The biggest issue I have right now is that loading the magazine on this gun is really difficult for me. I've been shooting for decades and I can work my way around loading Glock, M&P and other mags pretty easily, especially with loading tools like the standard Glock tool. The tool that Sig shipped with the gun appears to be designed for a 9mm. Since the magazine is a 9mm magazine with a spacer in the back, the Sig magazine loading tool presses down on the cartridge case too far back, and it just causes the bullet to tip upward. It's kind of useless. I'll have to see if something else will work.
Anyway, so far it's been a nice shooting gun for its size. It's definitely nicely made. Because of the tight lock up and magazine loading issues, I'm not sure it qualifies as an old man gun, though, without some extra tools. Your arthritic hands may vary...
