how to break a bull barrel python

I have a bull barrel python that has a big aristocrat rib on it, seemingly setup for PPC.

I thought that this meant it was fine for near max 357 mag loads. Unfortunately I was informed that PPC ribs were in fact designed to keep the front sight on the X ring when doing powder puff 38spl loads and using them for 357 was going to cause problems.

This is unfortunate since I only learned this useful fact after the rib flew off my gun tonight and whacked me on the head when shooting 357. The empirical record suggests that the rib is fairly heavy, in case you were wondering.

Here's how things should look:



And like magic, reality shows how they actually look:




The bolts sheared right off:





And it looks like they are locktite'd which will perhaps make removal more annoying.




The only good thing is that since I spend a lot more time working on colts than shooting, I have a backlog of guns I need to check out that can take it's place. Otherwise I'd be pretty pissed. As it stands it should be an interesting repair project.
