I just returned from a gunshow where I hoped to see a Kimber Solo but none were for sale.
I did run into an old friend who is retired LEO who along with his wife have also had a gun business for 25 years. I knew that he was a top 300 Kimber dealer so I asked if he had received a Solo and he responded that it was in his pocket right now but didn't want to pull a gun out while working his tables.
I asked if he has shot it much and he said he had shot it alot before he would trust it for carry. He said he loves the gun and this particular pistol has been flawless with everything he has tried in it and he was currently carrying 115 Gold Dots.
What his Kimber Rep told him is that they have found the Solo to be 100% reliable with 147 gr ammo, 99.9% with 124 gr ammo, and reliability with 115 gr ammo varies greatly from gun to gun. Some would not function reliably with any 115's, some would function with 1 or 2 brands, and some would be like my friend's and shoot everything. Also he said it is important to use only premium defense type ammo which is loaded "Hot" for complete reliability.
My friend said he has tried all the pocket nine's, and this the one he has decided to keep. He has had a Rohrbaugh and liked it but he perfers a gun with more visible sights, a slide catch and an American style magazine catch. He has always carried a Seecamp 32 as a backup but prefers these features on a primary CCW
