It took me a long time to find the Cybergun Smith & Wesson Sigma in Belgium, but once I copied the product number from the product's website and took this to the local gunshop, it arrived within the classical waiting period of 2 weeks...
The moment I bought it, the gun cost me 147.50 EUR retail. The company's French (Cybergun) so there's no gain for you Europeans by ordering it from a place using Dollars, just thought I'd mention that, knowing that I got my Anics Skif (Russia) when the Dollar was at quite a low value (1.33 USD for 1 Euro); it saved me a whole lot of money.
The guy from the gun shop was quite curious when I came to collect the order, so we popped in a CO2 jet, went outside and TRIED to fire it. Both of us being stubborn gun nuts, we -of course- hadn't read the manual... After loading 1 round, he pulled the trigger; it fired 1 BB, the slide locked back and everything seemed fine. Up next: a double-tap, 2 BBs were loaded, same story... Up next: a full magazine, I got to fire it, not reading the manual turned out to be a bad idea, there appears to be a safety at the bottom of the handle, not exactly the most visible spot to put one, let alone a handy location... I pulled the trigger, slide locked back with a full mag (minus 1 round) still in it, and a hissing sound was heard: Not good, I tapped the slide release with my thumb, slide moved 1/8 of an inch, had to PUSH it forward to close it, when the slide was closed, the hissing stopped, and strange enough: the hammer wasn't cocked.
The shop owner started reading the manual, I started unloading and field-stripping (I kind of knew in advance how it worked ) He mentioned the safety, I tracked the working of the safety inside the gun, seeing a pin/spring about 2 inches long and with a hook on every end. We unanimously agreed that a gun wasn't a good place for a safety, and whooped it out in no-time using but a hairpin.
Now, the gun's ultra-reliable!
I got home and couldn't resist emptying the mag a few times (about 80 shots) using the remaining CO2. As the mag started to cool, I noticed no drop in power or range. The gun must have some sort of constant pressure system built in I guess. Only the last 5 shots (sometimes only 4 shots), you feel that the recoil becomes quite sl w, until it won't cycle anymore. Yet again a nice feature: If the gun notices that the slide is cycled, but the hammer's left uncocked, it releases the last CO2; you are made aware of that by a hissing sound. This last feature is no more than logical if you look at the internals, there's a piston used for blowback, and until it's fully charged with CO2, it will keep draining CO2 from the mag, if of course the mag is near empty, the piston will try to charge, draining every last bit of gas, thus making it safe to remove the capsule of CO2 from the magazine... Splendid!
About the field stripping: It's easy to do and reveals a walhalla for every browning collector, you sea the classical browning HP locking lug system, but that's not the essence of this review, It also reveals a free floating stainless steel barrel inside a cast brass (and chromed) outer barrel, which has a fancy threading at the business end, I've tried all European sizes of thread, but couldn't find the right one. For those interested:
Inside diameter of thread in barrel: 11.1 mm
Outside diameter of fitting thread: 11.65 mm
I found a fitting thread on a cheap Chinese 1 Euro flashlight; it even had an O-ring ;)
About the power: well, having shot about every BB-gun pistol out there, I could say that this is about the hardest kicking, smoothest firing, biggest hole making' pistol out there... 0.25g BB clocked at 107m/s at 19 Celsius, after already having fired 10 rounds using that same capsule of CO2. (Cybergun premium BB: 18 Euro: 2000 pcs.)
As for the power in Joule, I'm not a rocket scientist, YET!
I must say, after peacefully de-installing the safety (nicer said than done) and oiling and deburring the whole thing inside out, this pistol gets 10 stars from me!
