Sig is certainly a great manufacturer - I've told this story a thousand times here (and else where) so the short version.
I owned 4 Sig pistols, 9mm, .45, .357Sig, .40
I found I shot GLOCK better, accuracy and fit just worked better for my paws.
I now own 5 GLOCK 9mm, .45, 10mm
Moral - (as we all know) Try before you buy, and keep and open mind - go with what WORKS for you.
