Sig Sauer X-Five ASP Silver Competition Part 2 Part 1
The Silver Standard for blowback action 4.5mm target pistols
By Dennis Adler
Sig Sauer’s airgun division has its eye on multiple markets from CO2 powered BB models like the WE THE PEOPLE 1911, to pellet-firing training guns like the new M17 ASP, and as far reaching as target pistols such as the X-Five ASP and ASP20 breakbarrel pellet rifle. The X-Five falls into its own classification within the Sig lineup as the only current pellet-firing target model (with adjustable rear sight) to use the 20-round rotary Rapid Pellet Magazine (RPM).
As a dedicated target pistol the X-Five ASP Silver uses the centerfire X-Five-type SAO (single action only) trigger. This almost vertical trigger design was used on the centerfire X-Five competition pistols, but this style trigger is not unique to target pistols or to Sig Sauer. Vertical triggers have been used on everything from semi-auto target pistols to custom Ruger LCP .380 personal defense pistols. One of the early designers of the skeletonized vertical trigger for the LCP, and other pistols, is Eric Galloway. His design for the LCP as a customized model was also adapted by Sturm, Ruger for a limited edition model that has since become known as the “Red Trigger Ruger” which was the best of the original LCP model .380 ACP pistols.
As Galloway explained it back in 2013 when he developed the first LCP trigger modifications, “The vertical trigger creates a change in trigger dynamics. The reason,” says Galloway “is to increase leverage on the trigger and reduce the bite during recoil from the pointy recurve at the bottom of the standard trigger [on centerfire guns with heavy recoil]. By almost flattening out the trigger we change the trigger finger interface so you get more leverage.” This does not noticeably change the weight of the trigger pull just the way it feels. In general, the trigger feels lighter, stacking becomes less evident, and the trigger pull seems shorter.
This is the theory behind the SAO trigger used on the X-Five ASP as opposed to the traditional curved DA/SA trigger used on the P226 ASP pellet pistols. In comparison with the P226 ASP (which is essentially the same platform as the X-Five but with the earlier 8+8 rotary magazine and the standard decocking lever).
Average trigger pull on the X-Five ASP Silver measured 5 pounds, 10 ounces with 0.625 inches of take up, very light resistance and a final pull of 0.187 inches with light resistance and a clean break. Single action pull on the P226 ASP averages 4 pounds, 10 ounces with a long 0.75 inches take up, a click, and then light resistance for 0.187 inches to a smooth break. So which trigger is better, the longer, lighter DA/SA trigger in single action or the shorter, slightly heavier SAO target trigger? For me, I find the DA/SA trigger a little easier, but having said that, the shorter take up and leverage of the X-Five target trigger makes it a smoother, more consistent pistol to fire. I also compared the trigger pull from my earlier review of the P226 X-Five ASP Black, which had a different feel to the trigger. I don’t know whether this constitutes an inconsistency in manufacturing or an improvement in the trigger with the latest X-Five ASP models, but the Silver trigger is smoother.
Speed of pellets
To wrap up Part 2, I’m going to chronograph the X-Five ASP Silver with Sig Sauer Match Ballistic alloy pellets (and you may have noticed Sig Sauer CO2 in the pistol grip), so this first shooting test is all Sig.
Average velocity for the 5.25 gr. alloy wadcutters was 401 fps with a high of 425 fps, and a low of 392 fps for 10 shots. Factory rating for the X-Five ASP is up to 430 fps. Saturday, I’ll run H&N Sport alloy wadcutters and Meisterkugeln Professional Line 7.0 gr. wadcutters through the traps (as I did with the X-Five ASP Black in May) and then head to the 10-meter range.
