If I know I won't be sitting for long periods, the appendix carry is tolerable for me when the barrel is even as long as a Glock 23. However, it is not ideal if I would be sitting for dinner or going for a long drive. In those cases, my Snubby is the best option and the Glock goes to the 4:00 position.
For someone considering appendix carry ITWB, what is the longest barrel length that you consider practical and comfortable? For me, the answer is 3" with my Galco StowNGo. I was just curious about your experience. Certainly if there are better ITWB holsters for appendix carry with longer barreled pistols, I am open to those suggestions.
