In my humble opinion, taking out the part about the manufacturer of the pistol in the 1911`s, I don`t think a 1911 is superior or or Glock or a CZ.
All pistols are very good and mostly more accurate in terms of selfprecision, then the shooter himself is.
In the end, it is alway the question, wich firearm suits me and fit me better. It`s no real use, in buying a Glock, if you can`t hit an open barn door with it and it`s no use in getting a 1911, if it just dosn`t feel right for you.
I bought a CZ75 Pre B and Sig P226 Classic. Where I coult hit with the CZ, I couldn`t with the P226. The trigger on the Sig just wasn`t mine, so I sold it and got a Colt 1911 Series 70 in 9mm and it feels really sweet and shoots very nice.
