Sig Pro SP2340Representing the latest trend in advanced materials composition, the SigPro is the most recent model to hit the real steel market following the Glocks and P99. Expanding on the attributes of the legendary Model P210, SIGARMS' tradition of quality and Engineered Reliability was translated into a lighter weight, low maintenance polymer frame design. The new SigPro goes far beyond the simple substitution of a synthetic for an alloy frame. Newly designed polymers now become the space age frame of this advanced pistol design, which also incorporates an integral accessory rail. The Sig Pro is SIG Arms' first foray into the polymer framed pistol area. KSC has faithfully replicated this advanced piece of weaponry for airsoft enthusiasts looking for something different. At first glance, its angular lines and smooth surfaces makes it look as if it were carved out of one chunk of metal.

The textured grip is handsome to look at as well as to touch. In fact I prefer the Sig Pro's grip over the P99's. The large "SIG PRO" insignia inscribed on the grip is very handsome! While the real steel version comes with two interchangeable one piece snap-on wrap-around grips (one rubberized, one regular), the KSC version only comes with the texturized grip which is not interchangeable. True to the real steel, the trigger guard looks a little too big but on firing with gloved hands, the reason became quickly apparent. Another quick observation is the long slide lock running almost half the length of the gun. Turning the gun over revealed the uniquely arranged rail guides for mounting lighting and laser accessories. Unlike the Glock's and P99's rails which runs down the side of the lower frame, the Sig Pro's rails run on the belly of the frame but are cut into the frame at opposing V angles to provide the required stress points for mounting accessories.

Alright, handsome the Sig Pro is but, how does it feel and perform? To be frank, we were not all that impressed, but then again our expectations could have been set unreasonably by its good looks! Picking up the Sig Pro brought a frown to my face as I realized how light the gun was. At 665g, this is no heavy weight. The Sig Pro is also rather "plasticky". While the surface finish is quite decent (especially when its meant to imitate polymer), we found some parts of the gun which of typically metal on other guns, to be made of plastic on the Sig Pro. An example is the slide guide rod. Metal parts are restricted to the trigger, slide lock, decocking lever, hammer, front and rear sights, and extremely cool looking triangular magazine release button

While the gun's levers and switches all worked smoothly, I must condemn the designer who came up with the safety mechanism for KSC's Sig Pro. While on the real steel version, the decocking lever doubles as a safety (when pulled down all the way and clicked in place); - the KSC Sig Pro has a spring loaded rod on the back of the trigger which flips out after you press a very small metal button (2mm diameter) protruding from the left surface of the trigger. In effect, with the spring loaded rod activated, the trigger cannot be pulled all the way back for firing since the rod makes contact with the frame as you pull the trigger back halfway. If that sounds like a mouthful, trying to deactivate the safety by pushing the rod pack into the trigger was even more painful since the rod is so small and requires fingernail assistance! I am simply appalled at how such a respected manufacturer of airsoft pistols can come up with such a primitive and gawky design. I am almost convinced that this was an afterthought.

Pulling the slide back reveals an open chamber design with a fixed nozzle. Interior mechanism is same as all other KSC guns. The magazine is quite heavy and sports a new looking valve that has a slab of metal covering the valve pin. On closer inspection though, it looks like not much has changed from the older designs, although the Sig Pro is advertised to use "Hard Kick" technology. Shooting it was downright disappointing with HFC134a gas. The 0.2g BBs we used seemed to sail out of the barrel on a slow arc-like journey towards our target. Range was at a disappointing 30 to 40 foot range with my friend's Benelli M3 obviously outranging and outspeeding the Sig Pro significantly (and with 3 BB's no less!). We had not adjusted the Hop-Up on our test gun but I suspect while the trajectory might be straightened, the sailing effect would get even worse.

Blowback was also quite weak, though no less weaker than any other KSC weapon using HFC134a. We have not tested durability using HFC22 but several adventurous test-squirts into the magazine improved performance somewhat. With the recent slew of strong contenders from Tokyo Marui and WA, I may have been spoiled. It seems that airsoft technology is maturing and airsoft pistols nowadays seem to be shooting faster and kicking harder. The Sig Pro is a disappointment in this regard if we had measured it up against all other new contenders. The style is top notch and external finishing is great, but if performance is more important to you, we recommend you look elsewhere.

Pick one up for yourself and see! We've put it under the Gas Pistols section!
