I recently bought some new mags for my 46 which are the same ones as the 41. They are very stiff to push down and after refilling these new mags about 4 times on the range my fingers do start to get sore. I am not a wuss but am getting older. With the artheritice acting up they can be a royal pain somedays for guys like me. Brownells can not sell across the border these kind of products to the Canadian shooters so it makes them hard to find for us over here. I do have one for my 9MM but its a unknown brand name that works quite well actually as well.
