No, the pistol cycles perfectly, for the comp I chose the small frame Tanfoglio type because they're readily available on Numrich, but the three port you see in the picture is actually for a .40 (.425" holes) not 9mm as advertised (they've since fixed that... almost) so it wastes gas, but I've also been going the wrong direction with my loads: heavier bullets and less powder. My current load is a 135gr bullet over 7gr HS6, it makes Major and is very soft, but the muzzle jumps a little; I have some 100s and 115s on order.How much do you want for your Czechmate?
