Magazine, 10 Round

Ohh nice, thanks for that link.

A little higher than i expected, but Its not too bad

I know this was an old post, but I too have been looking for magazines for my Colt Target 22. After talking with a Colt rep, I was told the magazines for this handgun are unique and other Colt magazines like the Cadet, Woodsman, etc. do not fit. I personally tried a Cadet and although it looks similar it doesn't work. However, the good news is there is a work around. The Beretta Neos 22 magazines are almost identical to the Colt Target 22 magazines with the exception of the feed lips and a slightly extended plastic base. The feed lip on the Neos has a slight forward bulge and left unaltered the magazine will not work. Using some electrical nippers to squeeze out the bulge and needle nose pliers to aline the lips I was able to adjust the Neos magazine in a couple of minutes. It now functions flawlessly in my Colt Target. The Neos magazines can be had for about $20 each. I ordered several from Midway, but they are easy to find.
