NOTE: The owner's manual states that this has BAX Hop-Up, but it does not.

Although this gun appears to have a half-cock safety, the pistol does not function like that and would need to be fully cocked and on safe to be carried at the ready. Carrying this pistol half-cocked with the safety on may cause accidental discharge and is not recommended.

Learn more about the SIG Sauer P226 in Dennis Adler's Airgun Experience Blog.

An incredibly realistic airgun that's a great all-day plinker and suitable for maintaining firearm proficiency. The slide moves and the gun feels and handles like the P226 firearm. You just can't go wrong with this pistol!

Verified Purchase

Things I liked: The replica accuracy and the trigger reset.

Things I would have changed: Adjustable rear sights.

What others should know: If you have the X-5 open, the adjustable rear sights are in the range to correct the impact point very well. I installed the mount rail of the X-5 open on the X-5 with a Feyachi 4-MOA red dot sight and it is perfect on target. A laser would do also. I have 40 rounds per CO2.

Things I liked: Realistic function of the gun.

Things I would have changed: Adjustable rear sight

What others should know: I was disappointed at first, but I finally realized I had unrealistic expectations for this gun. I am used to shooting super tight groups at 10 yds with my Beeman P17 and initially felt the accuracy of this gun was lacking. This gun is NOT a 10 meter target pistol! I found some handgun training targets (my favorite is "Dot Torture") and started following the exercises from distances dictated for the centerfire counterparts (like 3-5 yds) and fell in love with this gun. I got a Sig paddle holster and have been working on my draw and ability to quickly put BBs into 2" circles. What a blast, and the reduced distance to target means I can shoot in my garage. Much nicer on cold dark nights.

Things I liked: Almost everything. Realistic look and feel. Great balance. Reasonably strong blow back (M17 is stronger). The best CO2 loading system in the business. Better than average accuracy. High shot count. Extra magazines are inexpensive and easily available.

Things I would have changed: Like it's M17 sibling, the trigger pull is where this gun falters. At 8lb 2oz out of the box it has a lighter trigger than it's M17 counterpart, but not light enough (by a long shot) to avoid the consequences of a long, gritty and pretty unpredictable trigger pull. Worse, due to the design (the trigger advances the magazine) there's nothing that can be done to improve the pull in any substantive way. Sig should sacrifice the strength of the blow back and use it to advance the magazine thereby allowing them to create a more standard sear driven mechanism.

What others should know: Attaching a laser pointer sight to the Picatiny rail can greatly improve the guns accuracy even with the nasty trigger.

  • Russell from United Kingdom asked:

    I have a sig sayer p226 x-5 co2 pistol by cyber gun and I need a new outer barrel for it can you get spare parts

    • Robert from USA asked:

      Does the blowback feature use additional CO2, more so than a pistol without it? It's realistic, but given a choice, I would rather have more shots per CO2cartridge

      • Jordan from USA:

        Yes blow back systems use more gas to operate the slide. however in most cases it very little difference.

    • david from USA asked:

      The gun is fine IAM sure my question is this. I am very diabetic so nerve endings in fingers most of the time are very painful. I actually have many action pistols I can't shoot because the magazines are impossible for me too hold spring down to load them. I would welcome any advice.

      • Tyler from USA:

        I use a pair of tweezers to pull and hold the followers down most of the time. Not sure that would solve the issue for you though, but just a thought.
