I really hate it when a fixed sighted gun does not shoot to pt of aim with the preferred load.
Same here. Had to tweak the heck out of my Moms 36 front sight to get close to POI as your shots can be longer than 7 yards. If you keep it maintained and keep a coat of wax on it it will hold up well to the outdoors. Have plenty of blued guns that have been soaked thoroughly, including my pre 64 Model 70 in .270 that was dropped in a lake and luckily recovered. A tribute to Leupolds scopes here as the rifle was in 12 feet of water for 2 days and held up. Swapped over to a synthetic stock after that as Alaska's hard on guns and people
The 15 is a classic and will always be so. Stainless revolvers just don't have the same aura about them.
If you want to beat the heck out of it stainless does win but I take care of my weapons and just love a nice blue job that's aged like me over the years.
