Shot this drill this morning and had a pass on all strings.
Concealment garments: Columbia zip pullover shirt and an open front lightweight Propper jacket. Temps in the low 40s and foggy at Dallas Pistol Club.
Pistol/Holster: Gen 3 Glock 19 (my most carried pistol); RCS Phantom carried IWB.
String 1: 1.69
String 2: 1.94
String 3: 2.29
String 4: 2.45
String 5: 3.15
String 6: 1.64
String 7: 2.77
All shots inside a B-8 bull center and 3x5 head box.
I think this is a fairly good test vehicle for folks carrying concealed. I think strings 5,6 and 7 have overly generous time limits.
