If money is a factor, you could easily sell the shield to cover over half the cost of the .45.
Was totally sold on the 9mm Shield a few months ago after renting one at a local range and testing it against a Glock 43. Was not long after I had my own 9mm Shield. Then the 45 comes out and I read all the positive reviews. My own 45 Shield arrives shortly afterwards! I like the more aggressive grip texture of the 45 grip. The recoil even with 230 ball ammo is far less than what I expected. As to accuracy I only fired the 45 about 50 times and the results were on par with the 9 mm at 7 yard line. At 15 yards it looks like the 45 might be the more accurate pistol. I did not fire the 9mm that day but a side by side comparison is definitely on the agenda! I am not ready to retire my 9mm yet but the 45 is still a welcome addition.
Yabut... If you can't get that 230gr. down range in .6 seconds or less and on target, you could have 294-441gr. coming back at ya out of a 9mm. Sight recovery was a major concern for me. A .45 is just a bit out of my grip strength at my age. I feel that I have full control over the Nine. I don't especially do as I like but do as I can.first there are JHP in .45 ACP and second the .45 is a 230gr. vs. the heaviest in 9mm 147gr. do as you like.
