Q: Why do I want a .357 Magnum Automatic?                                                                                              A: Ballistic versatility, speed, and comfort! Bullets are available in a vast selection of weights and styles, and for the hand loaders, brass is commonly available. This makes the .357 Magnum Automatic very popular with hunters, target shooters, recreational shooters, and some law enforcement and military entities.

Q: What is the difference between .357 Sig and .357 Magnum ammunition?                                              A: Quoted from Yahoo Answers:“357 Sig set out to match ONE specific loading of 357 magnum in a relatively short barrel, and came close. However, you move beyond that one loading and the 357 Sig cannot compete any more, especially with heavy bullets of 140 grains and beyond".                                               See the full response

Q: Will I be able to shoot .38 Special ammunition?                                                                                       A: We are testing the pistols with a variety of ammunition. Some types of .38 Special ammunition will be able to be cycled simply by changing the recoil spring. The newly designed magazine will accept either .357 Magnum or .38 Special cartridges.  No spacer will be required. 

Q: Is this an actual 1911design?                                                                                                                  A: Yes, with a few improvements inspired by John Browning's 1935 Hi-Power. The extractor is an external design, like a Browning Hi-Power. The barrel is linkless  and the trigger is pivoting; both features are similar to the Browning Hi-Power.
