In this Table Top Review we’re taking a close look at the Sig Sauer P229 CO2 Blowback Pellet Pistol. This is the tabletop portion only, no shooting in this review as my Field Test Shooting Video will follow later on.
If you’re familiar with the Sig Sauer ASP P226 platform, the P229 version is the same general system in a more compact package, with one major upgrade: it’s optics-ready!

P226 vs P229 - What’s Different?
These two share the same general operating system (CO2 blowback, DA/SA, rotary-mag that works with pellets/BBs), but the P229 version changes a few important things:
Key Differences
Size: P229 is shorter (7.7 in) vs P226 (8.25 in).
Weight: P229 is lighter (35.2 oz / 2.2 lb) vs P226 (~39.1 oz).
Optics: P229 is optics-ready (SIG AIR reflex mounting provision); P226 platform is typically not.
Muzzle threads: P229 uses M14x1 CCW (P226 commonly uses a different thread direction/size).
Bottom line: if you liked how the P226 handled and performed, the P229 should feel very familiar, just more compact, with the bonus of being set up for a dot.
Walk-Around & Handling
The P229 has that classic SIG profile and a very “real pistol” feel in the hand, helped by the mostly-metal build and full weight.
Notable features and controls:
DA/SA trigger system: long/heavier first pull in double-action, then lighter single-action after the slide cycles.
Safety + de-cocker lever: functions like the real-steel concept — you can decock the hammer and run it DA/SA.
Accessory rail: for a light/laser (training-style setup).
Optics-ready slide: set up to accept the SIG AIR reflex-style mounting system (sight sold separately).
CO2 System and Magazine Notes
One of the standout features on this platform is SIG’s cam-lever, tool-less CO2 loading system, designed to make cartridge swaps quick and easy.
The magazine is a 16-shot design using twin 8-shot rotary clips. Practical tip: make sure pellets are seated properly in the rotary clip so they don’t hang up during cycling.
Pros
Mostly metal build with realistic weight and solid feel
Compact P229 size (shorter than the P226)
DA/SA trigger + functional safety/de-cocker system
Blowback action for realism/training value
Rifled inner barrel (pellet accuracy potential)
Tool-less cam-lever CO2 loading system
Optics-ready slide (big upgrade over older-style setups)
Accessory rail for light/laser
Cons
Fixed/non-adjustable sights
CO2 performance is temperature + cadence sensitive (rapid fire cools the system and drops power)
No last-round hold-open on this style of rotary-mag system
Rotary clips require good pellet seating to avoid occasional feeding issues
Final Thoughts
The Sig Sauer P229 blowback pellet pistol is a very “SIG-like” training/plinking platform: realistic controls, DA/SA operation, snappy blowback, and a compact duty-pistol footprint. The biggest tabletop takeaway is the optics-ready slide, which makes this version feel more modern than older CO2 pellet pistol designs.
Field test shooting (chronograph + accuracy) will follow in the next video.
