I've been carrying a P-64 (Polish surplus) 9x 18 since July in a pocket holster that was made for Walther PPK. It makes a rectangular bulge in my right front pocket but the gun doesn't print. In Ohio it's okay (legally) if people suspect you're carrying as long as they can't see the weapon. I've carried it everywhere and not gotten a second look. The bulge is less obvious if I wear dark pants and I have a few pair of Dockers "Classic Fit" cargo pants. The back pockets have the cargo flaps and are pleated for expansion, but the front pockets are like you'd get with any slacks, except there's a small zippered pocket below the right front pocket that's handy for a folding knife.
I can't carry at in the office but still keep the empty holster in my pocket and no one has commented on it, even my boss who has CCW permit and knows I do too. I recently bought a Bersa Thunder .380 and can carry it the same way, but am not carrying it yet as I only have one mag (for now) and have not practiced with it enough.
The P-64 was $159 about a year ago and I put another $10.00 in it for a lighter hammer spring. The double action trigger pull was waaay too stiff, and this fix brought it down to a reasonable level to make an accurate enough first shot at body mass.
Here's a link to a P-64 website:
http://p64resource.com/I'm going to the Bersa for a number of reasons:
The P-64 has the mag release at the butt of the pistol, next to the bottom end of the mag so it takes two hands to drop out the empty
The Bersa has 7+1 capacity vs 6+1 for the P-64
Thunderbore makes a .380 round that has higher muzzle energy than anything I've found in 9 X 18, so I'm not giving up any firepower with the switch.
The Bersa has better ergonomics and felt recoil is lighter. Wouldn't matter in a gunfight but it makes a difference when shooting 50-100 rounds in practice.
The Bersa was $259 new when I bought it a week ago. I was new to handguns at the time I bought the P-64 but was anticipating CCW and its size appealed to me. It has been reliable and accurate and I'd recommend it for someone who wants the lower cost (and ammo is cheaper), but if you want to spend another hundred bucks I'd recommend the Bersa.
