I've had a stainless Interarms Walther PPK in .380 for about 25years. The little gun has worked like a champ and would be one of the last guns to go if I had to sell out.

Carried it for many years in an ankle holster while on duty and iwb off duty at times and killed quite a few ground hogs, copperheads, skunks etc with it as it is suprisingly accurate.

Now with that being said I've heard of many not being totally reliable and there are probably better options out there today.
The Sig 239 in 9mm is just slightly larger, holds two more rounds in a better caliber and won't bite your hand and have sharp edges.
