As an experiment, I installed a Ruger ReadyDot on a Taurus TX22 Compact. The efficacy of this combination was surprising. Although the ReadyDot’s zero cannot be adjusted, Point of Impact was really close to Point of Aim at both 20 and 10 yards.
Body shots at 20 yards from a benchrest and headshots at 10 yards offhand were the test for zero used. No complaints whatsoever.
At 20 yards, the dot perfectly covers the four inch circle on the body of the target. For me, this made it very easy to aim without over-aiming. At 10 yards, it is slightly smaller than the head circle. Once again, I found this advantageous. This intrigued me so I shot the IDPA 5X5 Classifier. I didn’t time it but still shot at my normal cadence. Two Points Down.
I’ve created a drill I call the McGee, Shootist, Big Iron Challenge. It is a combination of the McGee Paradigm (3/3/3), Wild Bill Hickok’s shootist test from the American Mercury article about him, and Marty Robbins’ song Big Iron. The Challenge tests marksmanship at three separate distances; 3 yards, 8 yards Primary Hand Only, and 13 yards. It is 18 rounds total, six shots at each distance. In terms of proxemics https://thetacticalprofessor.net/2014/10/16/situational-awareness-and-positioning-part-iii/, marksmanship in the far phase of Social Space, and the near and far phases of Public Space are assessed.
McGee’s Challenge consists of three strings at three yards. One shot from the holster, two shots from the MidPoint, and three shots from Low Ready. The time limit for each string is three seconds. The standard is all six shots in the USPSA Metric target A zone in the head (2 inches x 4 inches).
The Shootist’s Challenge https://thetacticalprofessor.net/2024/08/02/gunfighter-challenge/ comes from the standard Wild Bill Hickok used in the Old West to see if a shooter was ‘good.’
The Big Iron Challenge was inspired by Marty Robbins’ song Big Iron.
“There was 40 feet between them when they stopped to make their play.”
The Big Iron Challenge consists of six shots at 40 feet/13 yards. It’s shot with Two Hands, Untimed. The standard is all six shots must hit in an eight circle, the IDPA -0 body zone.
The TX22/ReadyDot performed well on the Challenge. I’m very pleased with this combination of gun and dot.
Last Thursday, I shot an IDPA match that had a Pick Up Gun theme. I provided the TX22 Compact with the iron sights for one stage. Fifteen shooters fired six rounds each without any malfunctions. The match combined with the ReadyDot test totaled 143 rounds with no malfunctions. MiniMag solids were the ammunition used. This confirms my experience that the TX22 is a very reliable gun when fed decent ammo.

More of my Red Dot Adventures are chronicled on my Patreon page. For those who are considering putting a Red Dot Sight on their pistols, I’m exploring my testing criteria and outcomes, both yea and nay.

Seems like the “Big Iron” portion … or at least the first of the shots at “40 feet between them” … should be timed, primary hand only, in the A-zone.
