Paypal is affiliated with eBay and there are over 300+ Crimson Trace Laser auctions going on at the moment and every day of the week and all of them showing: "Pay with "
meaning that is OK to buy CTT lasers and pay for them via Paypal. I agree about Paypal anti-gun, anti-knife, anti nail clippers and all the rest of their bull#%$@*& but... I don't think the payment was reversed because your buyer mentioned Crimson Trace Laser, probably Koko1
used a stolen or somebody else credit card to pay for your item and when Paypal found out about the problem they reversed the payment right away.
Every time somebody pays via Paypal you have to make sure the buyer is "approved" or "OK to ship to" by Paypal...
