Designed for professional training, this high-end SIG AIR ProForce airsoft pistol is a replica of the U.S. Army issued P320-M18 9mm pistol in look, balance, and handling characteristics and engineered to SIG standards for precision, accuracy, and reliability. The M18 is the compact variant of the MHS chassis.

Since the early mid 1800s SIG Sauer has been widely regarded as a purveyor of some of the best small arms on the planet. Known for their fine combat, competition and personal defense pistols and rifles, SIG Sauer holds law enforcement and military contracts the world over and is the personal choice of thousands of firearm owners. People who trust their lives to a firearm put their trust in SIG Sauer.

The ProForce M18 features a polymer frame and metal slide with full blow-back action. An adjustable hop-up feature creates spin on the BBs for additional stabilization in flight, resulting in increased distance and accuracy. A 20mm M1913 Picatinny accessory rail allows for quick and easy accessory mounting, comes with an optic cut for the addition of the soon-to-be-released SIG AIR Red Dot Optic, and is available in 12g CO2 cartridge or green gas power options.

"I could not be happier! I received exactly what was advertised at an excellent price!

From Evike, I purchased the Airsoft green gas blow back version of the Sig Sauer M18. It is a less expensive and safer way for me to train on the real Sig Sauer M18 that I already own. Evike supplied a SIG ProForce M18 gas blow back hand gun with a magazine, manufactured by Sig Sauer, that is almost identical to the real weapon. What they advertised on their website was exactly what I received.

Also, their Customer Service folks are fantastic! I live in an area where the US Postal Service (USPS) does not deliver mail to my house (Rural mail delivery). When I saw that Evike was sending the shipment via UPS smart delivery (where the USPS delivers to my house) I knew the USPS would send the shipment back as "undeliverable." I pick up the phone and spoke with an Evike customer service representative who immediately re-routed the shipment so it would be delivered to my house via UPS. Many thanks!

There is no doubt in my mind that I will be purchasing more Airsoft weapons from Evike in the future!

"This is a very good replica. I have the M18 firearm. The weight and overall dimensions and most of the markings are the same. The only obvious differences are that the airsoft sights are smaller and fixed and aren’t night sights. The mount plate also has a different shape. The polymer part of the airsoft is also a bit darker colored. As far as markings go, the only difference is that the firearm says “P320” as well as “M18.” The airsoft gun shoots great. I like how I can use the extended green gas magazine from my M17.

"After seeing Sig Sauer had released their Proforce P320-M18, I immediately traded in my P320-M17 to pre-order this. Only difference is a shorter slide and it comes with 17rd magazine, but I think the strenuously long wait for it's arrival was worth it.
Just like the P320-M17, this pistol is a great shot. It fits the carry theme quite nicely. It's ergonomic and easy to manipulate. Though I was really hoping that this pistol would fix the liability issues with the P320-M17 and it's 21rd magazine.
The new P320-M18 17rd magazines are visually pleasing, but still have fragile plastic feed lips with no way to fix them, wobbly base plates, and stiff feeding springs that easily slip out of your grip. The magazines are the only downsides of both the P320-M17, and the P320-M18. I'm hoping that Sig will listen to the many warning of fragile magazines, and will work on the quality control to make better awesome airsoft replicas. I believe Proforce has lots of potential!
Looking forward to the red dot coming out soon. :)
