You may have misunderstood Gunnar or he may have misunderstood you, but it is general knowledge that the decocker model is definitely harder to work on (triggers) than the manual safety version........especially for a "newbie" to something like IPSC Production division the decocker version is safer to "make ready" than having to "thumb" down the hammer on the manual safety version (NOTE: "thumb" is being used as a general term here, most experienced shooters grasp the hammer between the thumb and forefinger to lower it)
