They are TackDrivers....
This is the one pictured above. It is a 1969 SUPER .38 that was modified by Dave Walters of Dallas, Texas. First groups with the stock gun were 3'...that is FEET...at 50 yards... New BarSto barrel, BoMar sights and long trigger and the next group with the same box of ammo was 3"...
This is 9 or 10 rounds at 50' two handed standing...gun helped me win a bunch of LE trophies...
70s vintage Combat Commander...
1952 Commander I carried from 1980 till 2007...10 rounds at 10 yards standing...
Marine Corps Course of Fire...
TALO Commander...10 rounds at 7 yards...the holes in the forehead are .22s...
Much easier round to shoot than a .45 and for whatever reason more accurate than 9mms from the same guns...
