If this is a Pietta the back strap for the hand grip flares back too much at the bottom. This tends to make the gun shoot high when pointed instinctively. One answer to this is to buy the hand grips for a 1861 Navy Colt revolver. These are the proper shape. The screw holes line up so it works fine. When the front sight for the Rogers and Spencer is available it makes an excellent replacement sight for the original one in the revolver. The original sights are not tall enough for accurate aimed fire making the revolver shoot high. A gunsmith can easily remove the original sight and replace it with the one for the Rogers and Spencer. At that point it's a simple matter of going to the range and filing the front sight until the revolver hits where it is aimed. That's a worthwhile update as the 1851 .36 caliber Navy revolver makes a fine small game handgun. During my college days I used a Euroarms 1851 Navy to put a lot of squirrels in the pot. The 36-caliber ball drops them instantly without destroying too much meat.
