just for cheap target practice. The 9mm rounds are cheaper to target practice with than a .40 or .45. I have a S&W M&P .40 with an ultra-bright micro LED light for home defense, but don't like the cost of shooting it for practice. It's a .40 which is ~10mm, so I think that the practice I gain shooting a 9mm is applicable to handling the .40/10mm anyway.
Also it has the sweet wood grain, double action hammer, and no shit hammer block safety... hell, you could have a round in the chamber and know that it takes a ton of pressure to squeeze the trigger back hard enough to engage the hammer for the 1st shot. After owning a semi-auto with enclosed firing pin assembly for so long, I've realized that I prefer a gun that has an open firing mechanism that i can visually see.
I'll be keeping both guns of course. And getting into skeet shooting next. Did some 12ga skeet shooting last winter, was amazing fun. And the plastic shells were almost half the price of the brass handgun/rifle ammo.
