As a dedicated wheel gunner (I own 9 of them) I do own two semi-auto pistols, a Ruger MKII and a Glock 23. The Glock has the NY#1 trigger and uses basically the same drill as my revolvers ( aim, pull heavy trigger and go bang) so it requires no new skills. I have the Glock for the very remote possibility of needing the firepower. The selection of the Glock was based on the recovery of a previously owned G22 recovered after a ride in a tornado and being buried for 6 months in 14" of Tennessee clay. I believe in the mark! They aren't pretty but they are reliable.
