None of the sellers I have met via Armlist ever had any odd advance communications, or apparent deception before meeting in person for the multiple, separate deals. Everything was simple and to the point, in a timely manner.
My last Armslist deal was Before the recent large increase in scams. One guy - a software engineer - has made about six deals with me, an hour away, in the same parking lot by I-40. I've also bought guns from about eight other guys I had never met: gun shows and Armslist.
And when buying used guns via Gunbroker, the feedback - both the quantity and overall grade (A+) - is a strong indicator of honesty and no critical info being excluded. The good ads are never created in a hyped, "breathless" style, as seen with some everyday email scams.
But each of these deals for used guns took place only after hours of reading about each model, and only involved guns manufactured by the best companies.
Do All of you guys/gals realize that there are specialist gun forums out there for CZ, HK (ie HKPro), Walther, Sig, Luger, S&W, SKS, AK etc? Many people state nothing here (on THR) about going to them for a good cross-section of seasoned info.
Never, ever be in a hurry with a gun type which isn't very familiar to you, or with an unknown seller, and any odd signals from your Inner Voice must be heeded.
