I found the stainless plugs much easier to instal for some reason. I actually lost one of the black ones, and installed the one I bought for my 617 in my 327. It looks fine because there already are silver pins showing through on the side of the gun. One more silver circle blends right in. My 340pd is the same way, The 442 is all black, but I would still order the stainless one for it.

I think the "plug" makes a lot of sense on any gun. But it makes more sense on the j frame centenials. The flag is completely hidden, and there is no way to tell if the gun is locked or not.

Has anybody done anything about the little hole that is left open on the side of the j frames? I did not want to leave it open so I cut a small circle from a black sticker and stuck it over the holes on both of my centenials. It actually doesn't look bad, and no dust or moisture can get in now.

These plugs are a great product, and the peace of mind is worth the price. Ed
