From Sig’s Website:

This is the one gun that changes everything, the new P250® is a modular pistol that allows the shooter to change caliber and grip size at will. One gun that adapts to perfectly fit any individual’s hand size, shooting style, and purpose.

The new SIG SAUER® P250 is a radically new kind of pistol that carries the renowned SIG SAUER quality – the performance, the accuracy and the reliability – into an exciting new range of unlimited possibilities, all built around a single, serial-numbered metal frame and fire control assembly. Choose the caliber: 9mm, .357SIG, .40S&W, or .45ACP. Choose compact, subcompact or full size polymer grip module. Select one of three grip sizes and two trigger lengths. Now it’s a fully customized P250. But then you can change everything to meet new requirements. When you have a P250, you not only have a high-quality SIG SAUER pistol that perfectly meets your needs. You have the foundation for building a new SIG SAUER pistol that will meet changing needs without the slightest sacrifice in performance.

Sig 320 / XM-17 — The US Army’s New Sidearm:

P320-compact

Frame: Like the Sig P250, this pistol is also modular, meaning that you can remove the internals (which are the serial numbered part and considered the “firearm”) and transfer them between other frame sizes. Frames available in full size, mid size, and compact.

Calibers Offered: 9mm, .40 S&W, .45 ACP, .357 Sig.

Sig 320 Reliability Tests:

Sig 320 Chosen As The US Army’s New Sidearm:

Sig 320 May Discharge When Dropped:

It has been discovered that the Sig 320 can accidentally discharge if the pistol is dropped on or hit in just the right spot. It appears that this isn’t a malfunction of the internals of the pistol, but rather a design flaw that allows the trigger to move and discharge the pistol when inertial is applied in just the right direction. It also appear that this problem only occurs with civilian pistols. The trigger on the XM-17 version is different and is not effected in the same way. Sig Sauer offers an upgrade as a supposed fix to the problem.

Sig P365:

After reviewing the following videos I would suggest avoiding the Sig P365, however if you insist, only buy this pistol is the manufacturing date on its box is after July, 2018. There are problems with models manufactured before then.
