In Standard or Open you can play with springs all you want. For Production it has to be 'production'...
CZ has a number of factory "aftermarket-like" accessories that get around the rule. That's one of the reasons why CZ is so popular among IPSC shooters, as I understand.I was just wondering about some of the guns that aren't 100% with stock springs; you hear alot about CZ's being oversprung...
Pretty sure this thread is about Production guns.Gosh....... If we are talking about Standard or Open, 1911 is all about aftermarket parts.
In the IPSC National 2007 Championship, there were actually several companies there selling many aftermarket parts.
It is hard to imagine aftermarket parts being prohibited in IPSC.
Which open gun does not have aftermarket parts all over it?
