Looks great but the holes were off. Had to remove .050 from the frame stop to line up my first hole to gun. Placed and screwed plate to gun, flipped gun to show top strap bottom, centered punched hole location, drilled thru hole , flipped over and drilled blind hole to hide screw head. Looks and fits great now.
I am a 79+ retired Mechanical Engineer, it was no problem to fix instead of sending it back . You should check the mounting spec for the S&W model 25-2 .

FREQUENTLY ASKED QUESTIONS
-
Federal or Remington & others makes works the best with the .025 thick Full Moonclips, which fit all the .38/357 standard moonclip. They allow the cartridges to have some movement or wiggle so that they will fall right into the chambers once properly aligned. Winchester brass does not work at all as the groove width is too tight/small.

Use this text block to discuss some commonly asked questions like shipping and returns, sizing, warranties, or product and company details.
-
There is no SAAMI specifications for the extractor groove and each manufacturer makes them as they want. The following list gives you a great example. This is why the diameter size of the brass is critical to proper loading, unloading and fitment. Cartridge diameter too big and moonclip too small causes the moonclip to bend. The cartridge should rotate within their respective place and wobble slightly when all cartridges are loaded.
-
If you are unsure about how to use moon clips for your revolver, or wondering which moon clip to use, call us. See the Contact menu tab.
