So I was sitting in line, waiting to pick my daughter up at school, when I came upon this thread via Tapatalk. I have a 642 with CT grips, but I have a hard time picking up the front sight quickly, particularly when practicing in low light. I have been thinking about picking up a 340 M&P, because it has a much better front sight, but haven't seen a non-IL version in my area. I want to thank wheelyfun66 for pointing out the one for sale on Gunbroker--it is now sitting comfortably in my front pocket! You guys are a great community and resource!
