Also have older nickel K-9 (Lady version). No need for customer service, except for ordering extra mags and recoils springs (every 2,000 rounds). Mine has the "4 mile trigger pull", which, being used to revolvers, I had no problem with. I understand newer versions have shorter trigger pull option. Quite pleased with my K-9, especially for one-handed shooting, either hand. Despite the fact it said "Lady", I carried IWB daily for about 2 years. Loaded, mine weighs exactly 2 pounds. Great for controlled rapid fire, but somewhat heavier than I wanted to carry, especially in warm weather. ' Did, however, load up the K-9 and carried again for about a week a while back while favorite ultralight j-frame was loaned to friend. A very accurate, reliable old friend. These days, commonly used as training gun for students with smaller hands.
