I got a G21 soon after they first came out and I've been carrying it concealed ever since. In the Summer I just use a fanny pack. I've tried a lot of different holsters, and under even a short jacket the Forbus paddle holster works great, too. I've always found a way to carry just about any gun I've wanted to carry, even my 4" Anaconda .44 mag.
Now a Ruger Bisley . . . . THAT might take a little thought. :cb2:
