I have and love the p238. Great for sliding in the pocket and heading out . Very reliable , I read about all the problems so I ran 400 rds thru mine to get peace of mind. 1 FTF and it was ammo related.
I held the Sig 290 and it felt awful. I shot the lcp and smith and wesson bodyguard. Between those to I would go S&W bodyguard 380.

If money is not an issue P238, if it is the

S&W or the LC9

Then again I am usually in cargo shorts or jeans so the M&P compact or Glock 23 is what I carry most if the time. When fly fishing the big stuff comes out.
