BB Pistols

Blowback vs Non-Blowback (NBB)

CO2 blowback mimics slide movement for realistic handling and draw/holster drills; expect higher gas use. NBB keeps the slide fixed for more shots per 12g and steadier FPS—often better for longer sessions and cooler days.

• Blowback example: Umarex 9XP CO2 Blowback BB Gun
• Non-Blowback example: KWC SP2022 CO2 NBB Steel BB Gun

Pick the feel that matches your training plan, then confirm rail space for lights/lasers and your holster fit.

• Trigger feel: single-action for light, crisp breaks; double-action for smooth, longer pulls; SA/DA for flexibility.
• Materials: metal slides add realism and mass; polymer frames keep weight down and may help CO2 behaviour in cold.
• Use case: blowback = realism cues; NBB = efficiency and consistency for accuracy reps.

Magazines, Capacity & Maintenance

Choose stick mags for value or full-size, drop-free mags for training realism—always confirm model compatibility before adding spare bb mags.

Typical capacities run 15–20+ BBs; many full-size mags also hold the 12g CO2.

• Keep it running: a light drop of approved oil on seals and the piercing area supports leak prevention and smooth cycling.
• After shooting: remove the 12g CO2 and store mags depressurised as recommended.
• Ammo: use clean .177 - 4.5mm steel BB; avoid deformed rounds to protect feed lips.

Stock up on 12g CO2, pick quality BB ammo, and use appropriate targets & traps with safety goggles.

Performance Tips

• FPS & accuracy: pace your cadence to reduce CO2 chill; set distances to your posted FPS.
• Sights & rails: confirm adjustable pistol sights and Picatinny space; ensure accessories don’t block controls.
• Cold-weather notes: NBB designs and measured shot strings help maintain velocity when temperatures drop.

Brands to Consider

Look for consistent CO2 performance and parts support from makers such as Umarex, Crosman, KWC, Daisy and more.

FAQ's

Blowback vs NBB—what should I choose?

Choose blowback for slide movement, recoil cues, and holster work. Choose NBB if you want more shots per 12g and steadier FPS for accuracy drills or cooler weather.

Both shoot .177-4.5mm steel BB—match trigger feel, sight options, and rail needs to your practice.

How many shots per 12g CO2 can I expect?

Counts vary by design and temperature. NBB pistols typically deliver more shots and tighter velocity spreads than blowback models.

Warmer temps help; rapid strings chill CO2 faster. Keep extra 12g cartridges on hand and rotate magazines to stabilise temps.

Do I need special maintenance or oil?

Use a light, approved airgun oil on seals and moving contact points, wipe rails after use, and store magazines depressurised.

Clean, smooth .177 - 4.5mm steel BB prevents jams and protects feed paths—pair with proper targets & traps and safety glasses.
