Shot mine today, WOW, I've never been this good a shot, ever. Do they dip these things in hot vasaline then stuff 'em in that plastic bag? Anyway, I cleaned and lubed it with PB Blaster dry teflon, a liquid spray with a carrier that evaporates and leaves a film of dry teflon lube. A shot of that made a big dif in that gritty, heavy da pull. The sa pull is very good. I hardly knew when it was nearing break point. This is my first cz and first centerfire da, sa pistol. I think I made a great choice here. Thanks to all for the great site. If anybody wants to see a pic, I'll post if I can.
