Just picked this gun up and after 200 rounds at the range I think this could be perfect for the individual who wants to own only 1 gun. Perfect for a day at the range and also for carry. Clarifying it doesn't have to be the 45 I would imagine the 9mm would be the same. This gun shot very well out to 15yrds and carries very nice. Recoil was a non issue and no malfunctions, I have some TruGlo sights coming and will be the only change made. I have both 9/45 in the shorter barrel and highly recommend them to anyone who asks but IMO the 4" takes it up a notch or two. Going to the range tomorrow and look forward to another 200-250 rounds with this gun. I did order my wife this gun in 9mm and should receive it in about 7-10 days
