Very long shot question (no pun intended)

[shaetuan]

Long time (lurker) first timer (poster) here; was hoping someone out there might know or could be so kind and help point me to the right direction: trying to compile a list of barrel twist rate on most of modern handguns out there. I tried Google, Wikipedia, and even ChatGPT, but does not seem like this information or database exists today anywhere. Even tried Googling specific handgun model and this information does not really turn up. Does anyone know where i should be searching instead?

Long back story on why I am doing this, but I am not having much if any success so far so was really hoping someone here on the forum might know a way. Thanks so much in advance

Probably have to do it the hard way. Go to each manufacturer website and look up each model.

It's probably not going to vary much per cartridge. It doesn't have much affect like with rifle cartridges. Most people don't care. I have lots of handguns and never checked the twist before buying.

Hardly a central respository of twiat rate data...but it mentions rates for several calibers

Thank you so much for the link, will take a look!

Thank you sir, sincerely appreciate your comment. I will pass that along.

SAAMI standards include the standard twist rate for each chambering.
You will find them listed in the rifle and pistol standards here:

Now that's not to say that manufacturers actually follow those standards.
The standards are generally derived because they are the most popular though.
