I have a bunch of HK USP small parts that have collected over the years. They are priced at 50% of their cost from a popular HK retailer. If my prices are off base, let me know, and make a fair offer. Flat $5 shipping via USPS regardless of what you buy, and I'm more willing to accept offers if you're buying more stuff. Payment through PayPal G&S, Venmo Gift, or Zelle.
