Siggy, you can't push manure with a Glock..no external safety.
I like the ergonomics of my Sig Pro in .40, but I have never warmed up to the DA/SA trigger. I like the Glock and P7M8 triggers. Of course, that would not explain the relative lack of zeal compared to other Sigs. I'm lucky, I don't keep manure local, so my Glocks are safe!
