I've never had any problems with any of mine, and others say the same, so I have to wonder, why did yours lock up?
I'd really like to know.
I'm sure there is no easy answer to that question, for many reasons. The first of which, is: It's a Ruger. You never know what type of fitting, filing, polishing, and finishing you may (or may not) see when you open one up. The saying "no two firearms are alike" should be taken quite seriously, when dealing with Rugers.
As I pointed out in a previous post, the main spring can shift on the hammer strut. In my SBH, it shifted to the right to cause the binding. That, alone,
shouldn't be capable of locking the action up. But, if my hammer strut is also bent slightly, that would seal the deal. I, apparently, was a little too excited about finally getting a photo of the protruding spring; and didn't inspect the strut thoroughly.
So, I should have been more clear about the potential cause(s), reasoning, and perhaps been a little nicer with the label ("stupid idea"). For that, I apologize.
But... I still maintain that it isn't a good idea. It's like disconnecting the brake line to the rear axle of your truck, because "the front end does 90% of the braking, anyway..."
