Thompson Patriot Twist Rates

[Flintleather]

Hello all, i’ve heard the early Patriot pistols had a slow twist rate and they fixed and sped up the later ones for lighter load accuracy. Does anyone know exactly what the rates were? I think maybe the early ones were 1:48? Were the later ones 1:24? Thanks in advance, Flintleather

TC catalog #1 states the twist is 1 in 48”

Judging by reading both posts you are probably right. I still shoot a 1988 model and it has a pretty fast twist with good deep rifling. I’ve owned two in 45 cal with both being very accurate.
