Springfield Tenon front sight




Just received a set of MGW three dot sights I ordered for my Springer WWII G.I. replica model.

Since MidWayUSA only offered wide or narrow tenon I ordered wide tenon since I was told that the Springers had a medium tenon front sight. I knew I would have to modify the tenon to make it fit.

Well, this just isn't going to work. To remove enough of the tenon to make it fit it is going to require basically making the entire sight blade several thousandths thinner. The front of the slide is milled with a semi circular cut, as if a circular saw was used to slot the slide for the sight, and the sight tenon has the matching semi circular base to fit down inside the milled slot.

Without putting the sight itself in to a mill, of sorts, to correctly remove the material needed there will be no accurate way to make the cut.

Is it correct that the factory sight is medium tenon? I think I am going to order the correct size tenon set instead of modifying these.

I just removed a Springfield front sight a few days ago, it measures 0.088.
Ask Midway if they will give you the measurement of their narrow tenon front sight.

King's gun Works no longer exists. I have had a hard time even finding Kings parts anymore. Brownells no longer carries them. I do think though, that Brownells carries the medium tenon front sight made by MGW. I am just not sure whether I have medium or small tenon.

Yours has a medium tenon. I don't remember the exact specs but small tenons are about .058 wide, mediums are about .085 and wide tenons are .125 wide. You can file a wide tenon down to the proper width if you work carefully with a file.

Exactly Dave, and thanks for posting the dimensions. Also the tenon hole can be opened up slightly with a square jewelers file also as it's still less than the late model(Colt after '88)tenon. The important thing is it fits snugly before staking. Also note only factory tenon sights have the moon shaped tang and is not necessary when replacing them and haven't seen an after market one with.

Well, the MGW i just received had this half crescent shape tang. That is what made it so difficult filing down the tenon. I had to try to file perfectly straight across the base of the front sight so that I was reducing the width of, not only the tenon, but the base of the sight as well. I pretty much screwed it up.

Well, that's cool except for the screwed up part and hadn't seen this included in other aftermarket sights , but there's a lot I haven't seen.
