I'm not familiar with the MPA...How does the porting effect low light shooting?I would add the MPA 380. Not as refined as the seecamp, but mine had been flawless. Nearly identical to the seecamp in size and around $300. When I got mine, about 8 months ago, they were easy to find (unlike the seecamp). Also has a ported barrel which makes the recoil very manageable
Seecamp availability is great as long as you have a week or 2. Most dealers don't stock them, mostly because they are a in the $450-500 range for a 32.
Actually, for what you get, I think that's reasonable.
