I am very familiar with the Model 41. They were an excellent pistol for 22 cal Silhouette Competition at the Club years ago.
Very nice piece! And great that it is a valuable nostalgic keepsake from your Grandpa! They mean the most to me as I am sure your pistol does to you! They are priceless!
The other thing is there is no problem with shooting the 41. It is a fine pistol and as long as you shoot good ammunition through it and take care of it as far as maintenance, cleaned properly and lubricated there is no reason for you to hesitate one bit to shoot it. Always keeping it in a gun rug after being lubed and kept in a dry place. I clean and properly lubricate all of my heirlooms every 6 months even if I do not shoot them. CONGRATULATIONS! On one fine pistol!
