Apparently according to Mike Searson at RecoilWeb.com........the rifling in your handgun barrel does not impart spin on the bullet! So that makes the Reformation OK...It's just like a handgun!
"Those of us who are rifle shooters know that the system of lands and grooves within a rifle’s barrel make our projectiles faster and more accurate. Longer or heavier bullets crave a faster twist rate for stabilization in flight.
Franklin’s Reformation does not offer this.
Neither does your handgun"

Well, I guess all those companies who are putting rifling in their handgun barrels are wasting their money and time.
OR
You are making crap up trying to support a ridiculous idea that steps backward in firearm technology hundreds of years because that company paid a lot of money for a good review.
Having read the article without editing ("Neither does your handgun for the most part "), it doesn't appear to me he was saying pistols have no rifling or impart no spin. He is (awkwardly and confusedly to be sure) saying that with a Reformation you are not getting rifle accuracy, you are getting pistol level accuracy with a SBR-like firearm.
