I stumbled on the following article while researching low-cost options for adding temporary sights to my East German Makarov. The gun is very accurate, but in dwindling light conditions at the range, it's very hard to get a good sight picture. The article below describes how to use a 1/16" round hole punch, some colored mailing labels, super glue, and floor polish to add Poor Man's Dot Sights to stock military sights.
Just curious if anyone has any better ideas... I've since purchased the hole punch off Amazon.com and have done a couple of casual test fittings. Seems to work great.
The best part is that this "mod" is totally reversible. With my pocket blow torch, I should be able to burn away any hint of my Poor Man's Sights in under 5 seconds and return the Makarov to stock condition.
