Safeties and controls

The P365 listing shows a manual safety, which is an external control you set by hand. The Hellcat listing shows no manual safety. Both listings show a trigger safety, which is built into the trigger mechanism. Neither listing shows a grip safety or an ambidextrous safety.

The Hellcat listing also describes a tactical rack rear sight, which is meant to support one-handed slide manipulation. The P365 listing describes an integral slim-line rail that accepts compatible compact lights and lasers.

Capacity

The P365 listing shows a capacity of 10+1, meaning 10 rounds in the magazine plus one in the chamber. The Hellcat listing shows 11+1. Its package includes an 11-round flush magazine and a 13-round extended magazine, which gives 13+1 with the longer magazine. Both listings include two magazines. Check the listing you are considering for the exact package.

Sights and optic readiness

Both listings show night sights. The P365 overview describes fixed X-RAY3 night sights for high visibility in low light. The P365 listing is marked Optic Ready: No.

The Hellcat OSP listing is marked Optic Ready: Yes. Its slide is cut for a compatible micro red dot optic, and it comes with a U-Dot front sight with tritium and luminescent elements. Which optic fits is a separate question, so check the mounting requirements of any optic before you buy.

Which to choose

Choose the P365 listing if you want a pistol with an external manual safety and a slightly shorter and lighter pistol by the listed figures. That listing is marked not optic ready.

Choose the Hellcat OSP listing if you want an optic-ready slide, an 11+1 base capacity, or the option of a 13-round extended magazine. Whichever pistol you choose, treat it as loaded until you have checked it yourself.
