Sold my Kahr PM9 for a Sig P290rs, and then bought a Shield. Both are in my carry rotation. Don't regret selling the Kahr. While it was very light and reliable, I have had issues with the company and their customer service. Carry the Shield more often than the others.
This is NOT my picture, but it shows the Shield compared to the Kahr. The difference is hardly noticable with a good IWB holster.
This pic is my P290rs compared to my Ruger LCR in .357, also in my rotation.
