3 buddies have the bobtailed Sigs and they have been reliable. I too do not like the boxy slide profile as it necessitates a specific holster. I have 4 other commanders and probably 10 quality holsters for them so the Sig was a no go for me.

I have the S&W version and its my daily CCW. I've only had it for about 6 months and have about 1500 RDS fired. So far it has been flawless and had zero issues.

I also prefer the trigger pull on my S&W.
