Short answer: Match Hellcat vs Hellcat Pro before you buy a barrel, a sight, or a plate. The two barrels do not cross over. An OSP slide and a dovetail sight are different parts.

Barrels: True Precision sells a threaded Hellcat barrel and a threaded Hellcat Pro barrel as separate parts. The Pro listing says 1/2x28. The standard Hellcat listing says threaded and does not print the pitch. A thread-on comp is a separate part from the barrel. Length is the same split as holsters: Hellcat vs Hellcat Pro.

Optics: Hellcat OSP is in the micro K/RMSc family. Red dot footprints. Night Fision sells a plate titled for the Springfield Hellcat to a Holosun 507K or 407K. The C&H plate title is Hellcat RMS-C to Holosun K. That listing says Hellcat, RDP, and Pro with an RMSc cut, to Holosun 407K or 507K. The Trijicon RMRcc plate title says 43X/48 MOS. The listing also names Springfield Hellcat OSP and the S&W M&P Shield OR.

Sights and laser: Night Fision 507K-height tritium sights fit Springfield Hellcat OSP and RDP. That listing does not say Pro. TruGlo TFX Pro fits Springfield Hellcat. HiViz FastDot H3 is titled Hellcat and Hellcat Pro. It is tritium plus fiber. Tritium vs fiber. The Viridian E-Series green laser is titled for the Hellcat, clamps on the trigger guard, and shuts off after five minutes. It is not a rail light. A light or a laser needs its own holster: Hellcat holsters and Hellcat Pro holsters.
