The other day while shooting my Ruger SRH, when I went to reload I looked down and noticed the whole front sight base and all had detached from the barrel.The great thing is I called Ruger and its covered under warranty.My question is has anybody else had this happen?

That's the first I've ever heard of the complete base coming off. I've heard of folks losing the sight blade after not installing it correctly.
Is Ruger having you ship the gun back to them? I had a Freedom Arms front sight base installed on my Redhawk. I sure hope it never decides to fly off.

Never had the front sight come off either of my SRHs. I have had the screw loosen up on a Dan Wesson and the sight blade fly off in the grass. Took the better part of an hour to find it.

Yes Ruger is having me ship the Gun back to them for repair.Kind of torn though gun season for deer starts here in three weeks.I shoot the gun using a scope so it will proably be returned to them after hunting season.I cant complain though The Ruger rep. on the phone was awesome ,very helpful and apologized for the problem. Just one of those freak things that happen.
