In a world of polymer frames, striker-fired triggers, and optics-ready everything some of the most capability-oriented end users continue to have at least some double-action/single-action pistol in the mix. The decision appears conservative in the face of it, but it stands since the design would resolve a particular set of operational issues.
DA/SA is not always easier to operate. It requires the shooter to operate two modes of trigger and regular use of the decocker, a proficiency trick that becomes increasingly difficult without training. However, the system is still earning slots on loadouts in the organizations that train hard, have standards and keep equipment in good condition.

1. A Chambered Pistol With Decocked Is Ready, Not Hair-Trigger
DA/SA pistols were constructed to a very simple carry condition: round chambered, with the hammer depressed by a decocking lever, and with the firearm loaded and at the ready with a first press. In such a set-up, the shot on the right is the heavier, longer, and double-action pull, and then the other two are single-action as the slide cycles back and forth.
This is a continuous state of decocking, a practice by training-oriented users instead of considering the decocker as optional. Their mechanics are simple, but advantageous: the first press is more deliberate without needing to adjust them to manual-safety during presentation. The design purpose has been explained as being transported with a round chambered, and the hammer was lowered with the aid of a decocking lever, in a fine dissection of TDA action.

2. The Trigger System Fits Better with High-Skill Shooters as compared to casual shooters
DA/SA performance is highly reliant on the ability of users. Common factory doubles are explained as between 10 and 12 pounds and the initial press can hurt poor grip mechanics, short trigger reach or uneven finger placement. That is, the design is selective: it is harsh to the random shooter and pleasing to the automaticity-training shooter.
That is one of the reasons why elite organizations can remain comfortable with DA/SA as the trend of mass-issue shifts. According to the same source, action work can also bring down the double action to approximately 6 pounds, and tuned systems can push single action down to the 34 pound range which has an entirely different handling profile to the teams able to standardize maintenance and qualification.

3. Certain errors that may occur in the real world during handling can be minimized with a Heavy First Press
Even very well trained shooters are capable of errors in trigger-contact when stressed. DA/SA never solves bad discipline, but the longer heavier initial pull may offer the slight cushioning effect of a premature discharge when hands are in motion and the concentration is divided.
This training discussion, when discussing trigger-contact errors, points out that they are recorded in highly-stress situations and that a longer/heavier pull may help certain users to avoid some unwanted discharges, provided they are still able to make satisfactory hits with their first shot. In a team where standards are used and frequent validation of performance is done against a decocked start then that trade can be attractive.

4. Follow-Up Shots Remain Rapid and Accurate When the Firearm is being cycled in single action
DA/SA pistols have a definite reset until they rest in short and lighter single-actions. The champions dwell on the succession of post deflections: fast, repetitive shots that can reinforce the cadence and precision of tight shots once the shooter is already aimed.
It is also one of the reasons that metal-chassed DA/SA handguns have continued to compete in the real-life shooting arena. Within the same training analysis, rivals are said to run tuned guns in which they can manage the first press, and the rest of the presses are optimized, with them also exploiting the recoil nature of a heavier frame.

5. Still Useful in Niche Environments Corrosion Resistance and Lubricity
Environment-proofing is not a promotional phrase of maritime and seashore users. Exposure to salt, changes of humidity, and continuous exposure to wet equipment may transform minor details of finishing to long-term reliability challenges. One common thing that user discussions of the SIG P226 Mk25 have mentioned is that lubricated internals with phosphate can hold the lubricant in a form that it will even out with use, even though it may feel rough at first.

One of the contributors sums up the practical advantage: “The rough texture does not lose lubricant that can also be used. The identical thread describes the Mk25 treatment as having been designed to resist rust when used in salt water like sea, which supports the fact that corrosion-oriented variants are still applicable to some mission sets. The latter are observed in the internal coating of Mk25 user discussion.

6. Dust, Grime and Slide Design Force Realistic Maintenance Planning
Not all standard classics of the DA/SA design are so tolerant of extreme particulate exposure, and known users note hardware characteristics that may help to exacerbate the issues. One poster in an argument about open-slide pistols simply says that with an open slide you get more dust and grime especially when they are working near the ground and that their performance is tapered as the gun becomes dirty.
The more significant aspect here is not that a certain pattern is bad, but instead, that elite units are likely to adopt systems based on what their real world considers, and organize inspection, lube, and cleaning cycles in such a way. The latter perspective can be summarized as a field-based opinion on the issue of open slides and grime.

7. DA/SA A bright training direction of Teams that impose Process
DA/SA pistols will correct sloppy operating habits: failure to use the decocker, living in single action, or failure to practice with a two-action pistol. The training article notes that a large number of casual owners do just that and such leads to false confidence and inappropriate handling patterns.
Elite units normally reverse that issue. They are capable of requiring the decocking operations between strings, certifying first-shot performance under the desired carry condition, and acquiring the automaticity such that the complexity of the system becomes habitual as opposed to a mental burden. Standards, repetitions, and enforcement that amount to institutional advantage are what makes the DA/SA viable where it would not be otherwise be liability.

DA/SA pistols have failed to live to 2026 as they are everywhere easier, lighter, or simpler. They are kept in high circles since the system is in line with hard training cultures, tight maintenance and particular environmental requirements.
As long as the initial shot is considered a core skill, decocking is considered obligatory, and the choice of hardware is adjusted to the climate and the risk of contamination, the DA/SA pistol can still be a combination of preparedness, controllability, and mechanical characteristics that are still appreciated by some teams.
