## What Reviewers Say

*Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.*

> Higher bore axis means the the bore is a little higher and when it comes back for recoil it can ride higher on the hand and a little more recoil than you get with a lower bore axis pistol.

> I'm not here to bash SIG but I apparently they haven't handled any of it really really well.

> Another reason why we could be having reliability issues with sig pistols lately is because of just the quality control issues that sig is having over the past few years.

> The modularity of the pistol is really excellent for a lot of reasons not just for being able to change sizes if you want to go from full to subcompact.

> Far as overall organ Onex are excellent it shoots really well very reliable which is what you would expect from a Sig.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P320 Compact with the ROMEO-RS Pro package tend to appreciate getting an optic and sights bundled at purchase rather than sourcing them separately. The 3.9-inch barrel sits in a useful middle ground between the full-size and subcompact, and most find it comfortable to carry while still easy to shoot well.

The Romeo-RS optic draws mixed feedback. Some shooters find it a capable carry optic right out of the box; others prefer to swap it for a different red dot, treating the included unit as a bonus. The XRAY-3 sights are generally well regarded as a backup regardless of what optic ends up on the gun.

The P320 platform itself is a common recommendation in this segment, and the Compact variant earns its place. Trigger feel and reset are consistent points of praise, though a small number of owners find the stock trigger pull weight heavier than they prefer and look to aftermarket options.
