Got a knock at the door and went to answer. Two gentlemen were standing there and immediately, one flashed the badge -- ATF. I locked up not knowing what to say or what they were here for. They said they were doing an investigation about some stuff I purchased off the web from Germany. I was thinking, oh great... The company where I got my parts had been illegally importing suppressors to internet clients. My gun in question was my Walther P22. They asked if I had purchased a suppressor and I quickly told them the truth, "NO!". Then, I made it clear by telling them that I am a criminal justice major, a former Marine, and the fact that if I wanted a suppressor, I'd get my sheriff’s signature, wait the 90 days for a background check, and pay my $200 for the stamp. This gave them some reassurance that I did nothing illegal. Luckily, I had the Pay Pal records from the purchase. I had gotten the parts off of eBay using "Buy It Now" and there was a record of my transaction that I was thankfully able to find. I had purchased a grip frame, a 5" target barrel w/ comp, a scope mount, and a scope. Not a thing more! I disassembled the pistol and also brought in the boxes from the parts that I had purchased. They were concerned because the Walter has a threaded barrel that could accept a silencer. It took a while to explain to them that the barrel was threaded in order for the barrel cap to keep the barrel sleeve in tact which kept the barrel from falling off the gun. They had a print out from the site in Germany that offers the parts. They had a picture of a suppressor and the adapter needed but I had proof that I didn't order a suppressor nor an adapter. More concern from them was that a suppressor could be made that used no adapter. I assured them, again, that I would only pursue legal avenues if I ever wanted a NFA item. I also reiterated the fact that I had received no such suppressor nor adapter. Anyway, the guys were nice, but it still made me a bit nervous since it seemed as if they had been accusing me of illegally receiving a restricted item from overseas. For any of you thinking about ordering from this place: http://www.kaehny.de/export/export.htm DO NOT DO IT!. I am going to make my way around several forums now and spread the word not to EVER purchase anything from this company!!!
