I have developed a recent fascination with Kahr pistols. I found an e9 for 399+tax. Is that a good price? The pistol appears to be in good condition although it has definitely been fired a lot. It seems like the K9 is a better option since the sights can be changed, but they sell for a ton online. What is a good price to pay for an e9 and a K9 these days? Let me know!
