I was "raised" on the old Colt Single Action Army so Loading one, skipping one then loading four more is more or less second nature with me. So much so that when I'm shooting my New Model Ruger I also load them,"five beans in the wheel." That works out two ways for me. One, I won't accidentally load six rounds in an OM Ruger and as most of my ammo is in boxes of 50 rounds it evens out when I'm done shooting.
I used an almost matched pair of Ruger Super Blackhawks as examples when I taught Hunter Ed. One was an OM and the other an NM I went out of my way to explain the difference. The kids caught on pretty darn quick.
When I was physically able to do my mountain and desert hikes my usual handgun was an NM Ruger Super Blackhawk with a 4 5/8" barrel. Even on those hikes it was five rounds and the hammer down on the empty chamber. On the mountains it was usually full power .44 Mags while hikes in the desert called for the first round up to be a shot load in case of an aggressive rattlesnake. Most would give a wide berth but the Mojave Green rattler while not all that common has the reputation to be one of the more aggressive snakes.
If you'd feel happier by doing the conversion I'd say it's your gun, do with it what you will. Personally, for the reasons stated above I'd leave it be as is. Like what's been said, they ain't making them like that anymore.
