I’ve owned several Sig’s, (2) 220’s, (1) 226, (2) 229’s, (1) 239 and my trusty 228.
Out of all of them if I had to pick one to keep and toss all the others I’d pick the 228, it’s a rock solid gun, but then again so are all my Sig’s. It’s very easy to carry; I carry mine IWB most of the time. You can find standard capacity mags just about anywhere, in new condition and fairly reasonable to boot. It will digest anything you can feed it.
My 228 is a primary house gun, keep it loaded with 13 rounds of 124 grain Gold Dot.
