The Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol is Sigs latest ASP (Advanced Sport Pellet) air pistol and like the Sig Sauer APS P320 has a high capacity bet fed magazine along with an easy load CO2 system. So who did the Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol perform compared to my preview testing of the Sig Sauer P320 ASP?
For my velocity testing I placed 5 rounds through my Chrony Chronograph using a brand new Sig Sauer CO2 along with Sigs Match Ballistic Alloy 5.25 grain pellets. This was the same setup when I performed the Sig Sauer ASP P320 testing. The Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol shot an average of 359 fps which was lower than my testing of the Sig Sauer ASP P320 as it shot an average of 413 fps. I am 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 pierced fully since some of the shots seemed to be weaker than others and CO2 output did not seem consistent even causing the blowback action to not fully cycle on a couple of shots.
Moving onto accuracy, my Sig Sauer ASP P320 shooting an 8 round group got around a 2 inch spread. I was able to get a tighter 1.5 inch grouping with my Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol and this was with 10 shots rather than 8 so the Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol may have shot a bit slower but it did seem to be a little bit tighter in terms of accuracy. The Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol was shooting a bit low and to the left for me in my accuracy testing but the rear sight is fully adjustable for windage and elevation so this can be easily corrected.
I strongly feel something did not go right when the CO2 was pierced using Sigs proprietary Cantilever Easy CO2 Loading system. There is only one way to do it so I know it was not human error in this case. perhaps the Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol needs a little bit of break in time is all?
Overall the Sig Sauer X-Five ASP CO2 Blowback Pellet Pistol is a really well made and fun gun gun to shoot. I love the high capacity belt fed magazine with is not heavy on the trigger at all like 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?
