Buy the magazine: SIG1058

Accuracy: It shot an average of 359 FPS, which was lower than my testing of the Sig Sauer ASP P320 which shot an average of 413 FPS. I'm not sure why there was such a difference since both guns use similar internal mechanics but I have a feeling the CO2 may not have been fully pieced since some shots seemed weaker and the CO2 output didn't seem consistent. I got a tight 1.5 inch grouping with my X-Five ASP. It was shooting a bit low and to the left for me in my testing but the rear sight is fully adjustable for windage and elevation so this can be easily corrected.

Pros:

• Full metal construction available in black or nickel finish
• Capability to shoot both 4.5mm steel BBs and pellets
• Full blowback action cycling
• High capacity 20 round belt-fed magazine
• Weaver/Picatinny rail for mounting tactical accessories
• Rear sight adjustable for windage and elevation

Cons:

• Blowback action drains CO2 quite quickly
• Non-rubberized grips can be slippery in wet conditions

Comments: The Sig Sauer X-Five ASP CO2 Pellet Pistol is Sig's latest ASP (Advanced Sport Pellet) air pistol. Like the Sig Sauer ASP P320, it has a high capacity belt-fed magazine along with an easy load CO2 system. The X-Five ASP is a really well-made and fun gun to shoot. I love the high capacity belt-fed magazine which is not heavy on the trigger at all unlike some other guns. The fully adjustable rear sight is something you don't often see on CO2 blowback action shooters so hopefully this is a new trend.
