they can try to use theirs heads not only for eating.
i think that ipsc much smarter organization than idpa . u know why in ipsc all targets not like in idpa without heads?
because they know that :the head is not in all people is a vital organ.
yes 100%.
it's start like this in all s2 guns in the club after 4-9k factory ammo. this is the first stage.
second stage: r. side totally separates from the frame. ~15k. i checked all of them every week to see the progress.
this shooters shoot now with .1911 /2011 platforms. now they over 20k.
mine old kit for cz 75 after i fixed it shoot now all types :low vel. and hi vel. and don't have lite strikes with 13 lb main spring.
all kit made from steel.
i don't know. but all cz and cz clones frames is castings
i have only parts. he sell his complete guns only in Europe .200 km from Prague.
sometimes they use Fiat mixed with Skoda .in that case frames cracks.
