I own a STI Trojan and a Sig Stainless Carry. Both are rock solid reliable. I carry the Sig the most simply because a Commander size conceals a little bit easier than the 5" STI.
Truth is when I put my right foot onto the footboard on my Electroglide the Sig never pokes the top of my thigh (I carry in a Galco King Tuk IWB) and occasionally the STI does.
At least that's how I justified
the Sig purchase to myself. Really, I just wanted another 1911
Now I'm looking into a 9mm 1911 and narrowed it down to either the Dan Wesson Guardian or the STI Lawman 4.0.
A well built 1911 is reliable which is why they have been around so long and maintain such a huge level of loyalty. Also in my safe is a Sig P226 & P239. Both reliable and the 226 has/is being carried by Seal teams....that's reliable. I will carry one of my 1911's without any worries and I am more accurate with a 1911 than any other pistol I have tried or carried.
Did I mention that 1911's are addicting?
JMHO & YMMV.
