I'm watching this thread with a lot of interest.
Years ago, on a whim, I bought an older well used 870 12g Wingmaster with the intent on building a HD shotgun. It has a long barrel; I'm not sure as I haven't measured it but it has to be 24" or 28". It also has a left-handed safety, which I thought would be a simple thing to reverse. Now years later it sits in a case untouched - but is a project I'd still like to undertake. I wonder whether or not to cut the barrel or buy a new one, keep the wood furniture or go with synthetic, should I go with sights or not, extended mag tube or none, & how much will it cost to reverse the safety.
This thread has helped!
