There's not too many things that Lloyd and I disagree about, but this is one of them. Don't do this on a whim, but if you really like the gun and do not intend to sell it as a collectable some day, go ahead and make it the way you want it. I have converted several guns over the years. Sometimes they were a low price opportunity, but sometimes there were 'what I always wanted'. What I always wanted except for the wrong barrel, caliber, finish, etc. So I have taken what I had and made it into what I didn't have but wanted. If you really like this gun and want it to wear a shorter barrel, go for it. You will enjoy it that much more and truly make it your gun. Another option though is to change barrels. All Rugers use the same threads. You could pick up a 4 5/8" barrel on the internet and have it fitted, keeping the original barrel in a drawer, 'just in case'. Probably wouldn't cost much more than cutting the barrel and remounting the front sight and refinishing it. 44 Man
