I have tried for over a decade to edc a heavy gun. 1911, 92fs, Full size Glocks, etc. I just can't do it.
The main reason is my work attire requires a very discreet carry. I wear a tucked in polo or tee most every day. I can't and largely won't dress around a gun. My lifestyle doesn't allow it nor do I care to do it.
Now, out hiking or milling around at the cabin? Bring on the big guns. 42oz OWB on a belt is no problem. In the cooler months, when i switch to a jacket or flannel, I go back to the 1911 or .357.
For day to day carry, though, my Shield. 45 comes in around 20-22oz and is about the limit I can carry IWB and not notice. Most work days, due to my attire, I carry a BG380 in my pocket. To the much gnashing of internet gun board teeth, I will sometimes ONLY carry a NAA revolver when the BG380 will print too much.
