Usage 

 
The Delta M is a full-size service pistol positioned as an alternative to more established brands. Build quality and range performance get generally positive marks. Aftermarket support -- holsters, sights, accessories -- is more limited than for Glock or Sig, which is worth considering if you plan to run a lot of accessories or need a wide holster selection out of the gate. Customer service experiences from Arex's support channels have been mixed based on owner feedback.

The Delta M FDE draws positive feedback on build quality. Owners like the FDE finish, the feel of the controls, and the ergonomic grip. Ambidextrous controls are a frequently mentioned practical advantage.

Range performance gets good reviews. Owners report reliable cycling across ammunition types and respectable accuracy out of the box. Recoil with 9mm at this weight is manageable for most shooters.

The main ongoing discussion is about the brand's relative obscurity compared to Glock or Sig Sauer. Some buyers are enthusiastic advocates; others want more established support ecosystems before committing. Aftermarket accessories are more limited, and that's a real tradeoff depending on your setup priorities.

Customer service is a mixed topic -- some owners report good experiences, others have had issues. Price-to-feature ratio is generally seen as favorable, which is the biggest reason people give it a look.
