I’ve had the Sig P938 and Beretta Nano. No experience with the Kahr, KelTec or Ruger. The 938 was nice and already comes with the night sights. It can perform like a full sized handgun at distance with some practice. The only negative to carrying it was that the safety needs to be disengaged at some point in the presentation and I have goofed that. The Nano points weird for me and is top heavy, so the gun tended to roll in my pocket and get out of position. The trigger does not bother me.
I now use a Glock 43 for pocket carry, but I only occasionally carry in a pocket. It is bigger than the P938 but weighs within a half ounce loaded. It is accurate and can take a lot of shooting, and I use it in IDPA matches sometimes. It is bulkier than the P938, and the Kahr or Ruger may be better as a dedicated pocket gun.
