Perhaps these suggestions and tips for a man that is an expert on the Rossi 92 will help.

Trouble removing the rear sight
Question: I received everything in good order; however, I'm having trouble removing the rear sight.
I have tried tapping with a punch and hammer both from right to left and left to right and it does not budge. Rather that hitting it harder, I thought I'd ask your advise.
Answer: Ok, the thing you will need to do is support the barrel. I use a bench vise with some leather jaw pads to clamp the barrel in. Now you can hit it harder. Once you get it supported, you drive the old sight out from the left side out to the right. I use a brass drift for this.

The Dovetail blank I got from you is loose. I thought it would drop right in, but it's so loose, it wants to drop right out... What's going on? Thanks,
Answer:
The current Rossi's have standard 3/8 x 60 degree cuts but they still don't spend a lot of time fitting the sights. If the dovetail cut in the barrel is too big it's because they hammered the Rossi sights in and swedged the dovetails out. Look at the dovetail from the side and you will see the metal is pushed up. Now, you need to do some Gunsmithing to grow some metal. Start by pushing the tops of the dovetail down with a flat face punch and hammer gently work across the dovetail . The new sight will cover these marks. Stippling the bottom of the sight works too, but worst case you may need to shim under the new sight. NOTE: Whatever you do resist the urge to stipple the bottom of the dovetail in the barrel if it's a big bore like a 44 or 45 cal. If you get carried away you can actually damage the bore. On a side note, I've seen Rossi's that had tight spots in the bore because Rossi forced the poorly fitted sights in.
