Decades ago I wanted a small size 45 pistol. I bought the Sig P245 thinking that would fit my needs. I took it to the range once, then sold it. The grip was too small for me to get a decent hold. Every time I shot the pistol I had to re-establish my grip. And that exasperated that hunk of back and forth piece of steel, otherwise known as the slide. Anyway, that's my story and I'm sticking to it!
I am glad you re-connected with the Kahr PM9! Been there done that too.
I guess that I'm a glutton for punishment. I picked up a Smith 340 PD this afternoon. I couldn't resist. LOL It should arrive next week, along with a case of ammo.
