can anyone tell me the size of the HK Match Weight allen screw? Are these available locally...interested in buying one but one of the screws is missing!

I would ask the seller to locate one before going ahead with the transaction. If he's got a product to sell, he should be the one making it up to spec to sell. That's unless you are willing to take a chance.

Buy the weight. Finding a screw to fit should be easy, the hard part is finding the match weight.

4mm dia.head X 10mm length, w/ 3mm hex. Not sure of threads, but I was able to find some that worked fine.

Thanks!

M4 or 4mm?

Take an example to ACE Hardware. They have the exact same screws in different lengths. Cheap.

You must have mistyped (or mismeasured) something - a metric socket head cap screw with a 3mm hex should be an M4x0.7, but that has a 7mm diameter head. It does, however, have a 4mm tall head.

But that would be an impossible screw because a 3mm hex is 4.6mm across the points, so if the head was only 4mm in dia, the corners of the hex socked would break through the sides.

Sorry! Should read:
7mm head dia. X 4mm head height X 10mm thread length w/ a 3mm hex.

Relevant contribution to this thread; I had a very unfortunate mishap w/my SS Match. After a trip to the range I began to take down the Match, and then was faced with a stuck screw on the barrel weight! After some sad attempts to remove the screw with my allen wrench (of the correct size), I finally had to resort to a screw extractor. I found that the combo that worked well for me was a 5/64 pilot hole and then a #1 screw extractor. Tap the back of driver to get a bite into the screw, and then remove. Here are the results:



It worked, but now I have a trashed screw. Anyone know where one might find a replacement of this size in black? Also the thread pattern just in case I find some online? Tried Adam with no luck.

To those who are interested, here are the specs on the required screw size for the USP Match factory barrel weight: Socket cap screw M4-.7x10mm. Maybe this will help someone out in the future.

Here they are for $.06 each. Sort of - you have to buy 100 of them for $6.23.

If you manage to find them individually anywhere, you'll probably pay almost that much for just a few of them.

If it's a short-head one, there are these too, a few cents cheaper but for 50:
