I decided to carry the SP01 Tac for the first time today. So far, so good with the weight, but it's only been 5 minutes and 4 of those were spent sitting at the computer. I'm going to go mow the lawn now. It will be a bit more of a carry test, but I don't see it as being much different than carrying the Heritage or other heavyweight pistol. It's just nice to have it out of the safe for a bit.
