## What Customers Say

*AI-generated insights from customer reviews*

Users appreciate the FNX-45's 15-round .45 ACP capacity most, calling it a significant advantage over traditional 7- or 8-round 1911-style pistols. Ergonomics and comfort during extended range sessions come up positively, and reliability with a range of ammunition is consistently mentioned.

For the tactical version specifically, the threaded barrel for suppressor use is a popular feature. On the downside, size and weight are common complaints for anyone considering it for concealed carry. Trigger feel is polarizing. Some adapt to it quickly, others find the DA pull too heavy. Holster availability for the unique frame shape is also noted as a practical frustration.
