Tim doesn't now CZs very well. The RAMI is designed off of the CZ 40B - the barrel lockup is SIG-like vice the 75 series. The C100 is a alloy framed clone of the CZ Compact - close also to the PCR, but the WHOLE gun is thicker in the frame, not just the top of the frame.
I am also surprised Tim has not yet learned how to PROPERLY decock a DA/SA manual safety hammer gun. Using the so called idiotic "pinch method" is wrong. [In another video Tom says you HAVE to use the pinch method - an even dumber statement]. Drop the hammer on the support thumb and roll it out, and it decocks to half-cock - the PROPER position to carry the weapon in, and a KEY feature of the 75 series which shortens the DA pull.
BTW - I don't hate Tim - he makes darn good videos and is generally well informed. However I just don't like the errors - especially about decocking.
