I was really interested in the sig piston 716 a couple years back and then one day it no longer existed. Poof...
You dodged a bullet; mine never ran right and I'm definitely not alone. Sig's support was terrible about it, too.
I rolled the dice a second time with the "legacy" MCX and it's probably my favorite rifle and the first one I'd grab out of the safe if I could only take one with me for the rest of my life; they later issued the recall (probably preemptively.....shoutout to that nerd NutNFancy) and they were absolutely fantastic to deal with. They got me a label, a truck pickup, a free Geissele trigger (lol wtf right?), free sling and swag, and a $75 gift certificate to the Sig store....and they turned it around in a week.
I'm not sure what changed at Sig in terms of product design since the first iteration of the 716 to now; the P365, P320, MCX / Virtus, and now Cross are pretty "risky" projects that push the envelope for a massive company like Sig. I know they've had their hiccups and the lack of support across generations (MPX and Virtus vs. Legacy come to mind), but they are taking huge strides in my opinion, and their contract awards seem to validate their progress.
