I have stayed away from Kimbers for many of years. I carried a Colt 1911 Combat Commander from 1970 until 1987 as a PDW When I switched to Glocks. I still kept the Colt 1911's because i shoot them so well. Back in the day When I was an active LEO I carried a Colt Model 1909 in .380 as a secondary BUG switching off and on with a 3 inch S&W model 36.
Whith the last 8 months I have started shooting the 1911 again. Kimbers in fact, I am carrying a Kimber Tactial Pro II more often then my Glock 23. I am still shooting the G35 in the IDPA type shoots. My Recreational/Range gun is a Kimber Gold Combat Stainless ll. No problems with either of these guns. Accuracy is outstanding on both these guns.
I have been giving some thought to the Solo as it reminds me of the Colt 1909 and how easy it was to carry. I always wished the Colt was in a 9mm instead of the .380 ACP
Over the years I have tried the Kahr Mk9, CW 40, Kel Tec P3at, Kel tec .32 Auto S&W 642, S&W model 60, 2 inch and 3 inch, and the Mini Glocks; still I remained unsatisfied. I have shot the other 9 mm Kel Tec's, Kahr's and numerous 3 in barreled .45 ACP's. They were all nice but still just short of what I was looking for.
Nothing wrong with the listed guns but still wasn't what I was looking for. Each of them had their own strong points but still left me wanting something. It was like eating a hamburger without a thick slice of onion, good but could have been better.
Ii have read review after review concerning the Kimber Solo, good and bad. But until I get my hands on one and shoot it. I will still be left wondering. The 9mm has mostly been my choice of min caliber as a pocket/deep concealment SDW but I have strayed below that caliber once in awhile.
