I don't understand these manufacturers not making ambidextrous weapons. There are very few that do and it is not that bloody hard. I'm a lefty too and because the Colt is an open class IPSC you can do anything to it, so it is fully ambidextrous (also because IPSC requires "weak hand" shooting in the matches). MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!
