PF9 Mark II Update

My new to me PF9 has performed beautifully for me.  It's been to the range three times kicking about 250 rounds down range each time.  No malfunctions to speak of.  But I've got a problem.  I can't seem to trust the PF9 design as much as I used to.  Having the takedown pin walk out on me makes me wonder when it'll happen again.  What if it happened when I really needed the gun?  So I found a screaming deal on the Sig P239.  Hopefully it'll be small enough to become my every day carry gun.
