Well, the SIG P210 is possibly the most accurate, tightest, smoothest, most reliable 9x19mm handgun in existence, with the best single-action trigger you may find anywhere... including expensive 1911s. Of course, the prices range from high ($1,000 for a super-duper deal on a used basic model) to psychotic (about $4,000 for the most expensive variant new in the box
). They make a P7 seem like a crude lump of pig-iron by comparison... and P7s are
nice.
Downsides? Aside from price? Hammer bite. Magazines are expensive as hell and only hold 8 rounds. Eurotrash magazine release.
Value is relative, but for the $1,500 you can expect to spend if you shop around a bit, they are much better quality than a semi-custom 1911 at the same price point in my opinion. And they will last pretty much forever.
I had to sell mine, and unless I find a deal I can't refuse, I probably won't get another one. But if you want the best 9x19mm gun there is, there is the P210, and then there is everything else.
