Taurus 709 - great choice at about $370
They don't
shoot low - the factory simply does not take time to adjust the sights before they are shipped out.
With 9 rounds, you can adjust the sight to perfect POA/POI
Much better build quality than the Kel Tecs
Kel Tec PF9
Very thin and very light, but only marginally so vs. the Taurus
Sights adjustable for windage only, unless you want to shim or sand the rear sight.
Can post respectable groups when slow fired, but I've never seen anyone put good groups together rapidly
If you shoot a DAO revolver well, you'll shoot well with the KT, but for most the trigger is the worst thing about them
Polish P64 is cheap and is thin and well built
Drawback is a horrid double action trigger - even with a hammer spring change, which is a MUST DO, (only about $8) the DA pull is easily 18 lbs
Single action is very nice, but since they can't be carried cocked and locked, it's a moot point, as your first shot will be horribly heavy
They're cool guns, and I recommend buying one, but more for the history and solid build than for carry
They also use 9x18 ammo so you'll have to stock up, rather than having the convenience of picking it up at wal marts and the like
From Kahr Arms website:
http://www.kahr.com/PA-1B/review_ch0905.html
Kahr Arms emphatically states that the recoil spring must be replaced after 3,000 rounds. I suggest more frequent change if +P or +P+9mm ammunition is fired
As far as mixed reviews, each of the pistols above have mixed reviews as it pertains to reliability; even the expensive MK and PM series of Kahr which will run over 600 have all kinds of detractors.
Get the 709, spray the pee out of it with brakekleen before you shoot it, and allocate yourself 9 'sight in' rounds before you even put it into action and you'll be a happy camper.
