Where to find 3mm X 0.5mm thread plug

[Holleyman]

I have a CZ-527 and removed the rear sight. I am looking for 3mm by 0.5mm plugs to fill the holes to keep water and dirt out. Brownells has plugs but they are all imperial sizes.
Anyone know where to get metric thread plugs?

Have a look at the RC supply places. Failing that you may have to cut off and slot an M3 screw.
