well..
SIG 239 is in the $750+ range: that's a lot for a "plinker", IMHO.
On the other hand a 9mm 1911 can very easilly be up there, too...
Possible exception would be the Taurus 1911B-9 @ under $500 : it has a lot of standard features that would cost a whole bunch of $'s if you were to take a mil-spec 1911 and have them done in a custom shop.
p.s. Picked up an almost never shot S&W 3913 last year and to call it an "all metal SHIELD" with the big plus (again, IMHO) of a decocker/safety & DA/SA is right-on the spot!
