The two that finished
The US Army's XM9 trials in 1984 were meant to settle the sidearm question for a generation. When the testing was done, only two pistols had completed it satisfactorily: the Beretta 92 and the Sig Sauer P226. Beretta got the contract and the 92FS became the M9 in 1985. Sig got something arguably just as valuable, a reputation that carried the P226 into police holsters and, from 1989, into the hands of Navy SEALs as the Mk25.
Today both pistols look old-fashioned next to the striker guns that dominate duty belts. Yet both remain in production and both still have loyal followings among officers, instructors and home defenders who want a hammer, a long first pull and a lot of steel slide over an aluminum frame. If that is you, here is how they actually differ.

Controls: the real difference
Beretta: safety and decocker on the slide
On the 92FS, a lever on the slide does two jobs. Push it down and it decocks the hammer and puts the pistol on safe. Push it back up and you are ready for a double-action first shot. The upside is a manual safety for officers or agencies that want one. The downside is that the lever sits on the slide, where it can be bumped on during slide manipulation, and it requires training to sweep off under stress.
Beretta also made the 92G, which turns the lever into a spring-loaded decocker only, and the 92D, which is double-action only with no lever at all. Many duty buyers prefer the G configuration, because it keeps the decocking function and removes the risk of accidentally leaving the gun on safe.
Sig: decocker on the frame, nothing else
The classic P226 follows the P220 pattern: a decocking lever on the frame behind the trigger and no external safety. Your safety is the long, heavy double-action first pull. You draw, press, and the gun transitions to single action on its own. To holster, you decock with your thumb, which sits naturally on the lever.
That simplicity is why many officers who trained on the P226 never wanted anything else. It is also why some agencies avoided it: no manual safety means the decocking discipline and holster discipline do all the work.
Sig has made the P226 in other trigger systems over the years, including DAK and single-action-only versions, so check exactly what you are buying, especially on the used market.
Shooting character
Beretta 92FS
The 92FS's long 4.9-inch barrel, weight and open slide make it one of the softest-shooting full-size 9mm pistols around. The open-top design helps ejection and makes a stoppage easier to clear. The grip is thick, though, and the double-action reach can be long for small hands.
There is one bit of history every 92 buyer should know. During US military testing in the 1980s, slides separated on some guns. Beretta's investigation concluded the slides had passed proof and inspection and blamed overcharged ammunition. The FS designation marks the fix: an enlarged hammer pin that engages a groove on the slide so a cracked slide cannot fly rearward off the frame. It has been standard for decades.
Sig P226
The P226 carries a shorter 4.4-inch barrel in an enclosed slide, and it tends to feel more compact in the hand. Its bore sits relatively high above the hand, as on most classic hammer guns, so expect a bit more muzzle flip than a low-slung striker. Many shooters find its grip easier to reach around than the 92's, but that is worth testing with your own hands.
Optics and accessories in 2026
Neither classic was designed for red dots. The modern M9A4 adds red-dot compatibility and 18-round magazines, and Sig has offered optics-ready P226 versions under its Legion line. If you want a DA/SA gun with a dot, look at those newer variants rather than trying to retrofit a classic 92FS or P226.
Both pistols have rails on their modern versions, so a weapon light like the Streamlight TLR-1 HL fits, but light-bearing holsters for DA/SA guns are fewer than for strikers. Verify a fit for your exact gun and light before you commit.
Magazines and spares
The 92's long US military service means magazines are everywhere. Stock factory Beretta 92/M9 magazines and you will not run short.
P226 magazines are also easy to find, though be careful with older and newer variants that differ in capacity and base plates. Ammunition Depot's Sig Sauer magazines category is a good place to start; check the listing names your exact model.
Holsters and duty support
Here neither classic matches the modern striker gun. Major duty holster makers still offer Level II and Level III fits for the 92 family and the P226, but selection with lights and optics is narrower. Plain duty holsters are easy; specific combinations take more searching. Browse duty-oriented holsters and confirm the fit list names your gun.
Armorer support is good for both, thanks to decades of agency use, but fewer new armorers are trained on DA/SA guns each year.
The training question
DA/SA guns ask more of the shooter than strikers do, and that is the real cost of choosing either classic.
The first shot. Both pistols start with a long, heavy double-action press that cocks and drops the hammer. Every shot after that is a short, light single-action press. Qualification courses often start with a draw-and-fire string, so the transition from the heavy first shot to the light second shot shows up immediately in scores. Shooters who practice it find it becomes natural; shooters who do not tend to throw the second shot.
Decocking under stress. Whether it is the 92's slide lever or the P226's frame lever, decocking has to become automatic before holstering. A cocked DA/SA gun in a holster is a single-action pistol with no safety, which is not how either was designed to be carried.
Mixed fleets. If your agency issues strikers and you carry a DA/SA gun as an approved personal option, expect extra training time and possibly separate qualification.
Dry practice helps with all three. Do it with a confirmed-unloaded pistol, no ammunition in the room and a safe backstop, and lock the gun up when you are done.
Buying used or new
Both turn up as police and military trade-ins. Inspection points are the same: check the slide and frame rails for wear, look for cracks around the slide, check the locking block (Beretta) and test the decocker function with an unloaded gun. If you are not sure, have a gunsmith inspect it. Check current price new versus used; the gap varies and sometimes favors new.
Decision guide
Pick the Beretta 92FS if:
- You want a manual safety, or your agency requires one.
- Softest recoil and the longest sight radius matter most.
- You have larger hands or do not mind a thick grip.
- You like the idea of the most widely available DA/SA magazine on earth.
Pick the Sig P226 if:
- You want decocker-only simplicity with no safety to forget.
- You prefer a slightly shorter, more compact-feeling full-size gun.
- You have medium or small hands that struggle with the 92's grip.
- You want a classic with a strong special-operations reputation.
Pick neither if you want maximum holster and optic support; a modern striker or the M9A4 is a better fit.

Frequently asked questions
Why did the Army choose the Beretta over the Sig P226?
Both completed the 1984 XM9 trials satisfactorily. The Beretta 92FS was adopted as the M9 in 1985. Both designs went on to long careers with military and police users.
Does the Sig P226 have a manual safety?
The classic DA/SA P226 follows the P220 pattern: a decocking lever and no external manual safety. Sig has offered other trigger systems, including DAK and single-action-only versions.
Is the Beretta 92 too big for duty?
It is large. The grip is thick and published weights are around 34 ounces, but many officers carried it for decades; try it in your hand first.
Which has better duty holster support today?
Both are supported by major duty holster makers, but neither has the depth of a Glock. Check exact fits, especially with a weapon light, before buying.
