My wife carried an Interarms PPK .380, and as far as accuracy and reliable feeding with a variety of ammo (at least 8 diff commercial loads in both HP and FMJ, no misfeeds) go, it's been totally flawless. However, she did have the extractor break recently after only abt 500 rounds through the gun, and I've seen a number of posts from people with Interarms PPKs that have had the same problem. S&W is handling the PPK repairs (and US manufact?) now, but as to whether or not the parts will be of better quality, I don't know. She really likes her Walther because it fits her tiny hands and the recoil is pretty mild, but she's had my Kahr P9 while its being repaired and I'd like to convert her to one of those permanently (as long as she gets a new P9 and gives me back my baby!).
She took a handgun course, got her CCW, and started carrying recently after she came home from work to an in-the-act-of-being-burgled house with the intruder hiding in the understairs closet. To make a long story short, he exited while she was upstairs discovering the ransacked bedroom (downstairs was not messed up) and we lost nothing of value (God bless the Homak 2 locks-per-door security cabinet that resisted his crowbar). But, the close call scared both her and me (esp. since he had taken the time to pull out pics of her from our recent Caribbean vacation and put them on the table for his, ahem, "perusal"), and she went from gun-ambivalent to pro-CCW almost instantly. She's a good shot, properly trained now, and I want her to have the best possible hardware if, God forbid, she ever needs it. Unfortunately, that will NOT be an Interarms PPK.
As an interesting aside, both the responding LEO and the two retired LEO's who worked for the security Co's we got estimates from came to the same unsolicted conclusion. Namely, that the presence of my gun books/mags lying about and the fact that we own guns as evidenced the gun security cabinet (now replaced a big-a$$ safe), likely led the apparently sexually disturbed BG to think that the wife may well be armed, and that his best option was to leave quickly while she was someplace without a clear shot. Well, next time, she WILL be armed! Screw those types who would take away our God-given right to defend ourselves as we see fit ... and their million moms while I'm at it!!!
