No, this will not work in the SA Hellcat Pro.

Good evening to you!! The Rival Arms Precision V1 is meant to fit the Springfield Armory Hellcat. The man difference between the Hellcat and Hellcat pro is the Size and Dimensions:
The Hellcat Pro is slightly larger overall, with a longer slide (3.7 inches vs. 3.0 inches). So no this will not fit the Springfield Armory Hellcat Pro. Hope this was helpful. Have a good rest of your day.

Hi Brian and welcome. No, a standard Springfield Hellcat barrel will not fit the Hellcat Pro. While both are 9mm pistols, the Hellcat Pro has a slightly longer slide and barrel (3.7" vs. 3.1").
