Satt å kikket litt i IPSC production list.
Under CZ - CESKA ZBROJOVKA sto det: Also approved are variants with original Ceska Zbrojovka (CZUB) barrels which are longer than standard (e.g. SP-01A, SP-01DK, SP-01DK Shadow), provided the barrel length does not exceed 127mm, and provided all other aspects of these variants fully comply with all other Production Division rules.
Måtte jo sjekkes ut, og fant ei dansk side, http://centerarms.dk/product.asp?product=456
Ser der at den danske utgaven er 4 mm lenger en standard.
Noen som vet hvorfor
