hmn ok. I touched one once, it was clearance in a store. the safety was broken. and it said cybergun on the package, so no clue who makes them. the first site i opened when doing a websearch thou indicates that it's made by KWA.. which surely is a good sign? thou I only ever used NS2, which is does not say if this is or not.
The Tanfoglio Witness is a co2 powered 1911 replica. It can be blowback or non blowbback, and there are specials too. I do believe they are made by cybergun.
AFAIK (and will stand corrected by those more knowledgeable than me) in its tanfoglio form it is 4.5mm calibre and classed as an air pistol. The cybergun version is for airsoft.
I haven't used one but, when they first came out they sold like hot cakes. The RFD's couldn't restock fast enough. I believe the blowback is better than the non blowback.
Awesome pistols, kick hard, very reliable, both gun and mags, nice and accurate + the big seller is the tanny is based on the CZ75 - the best feeling pistol of all time. Fact.
If you can get hold of mags easy enough, I say go for it!
