I've been thinking about getting one of those RIA 10mm's. Let us know how it shoots.
Your dealer and the sender obviously need to get their acts together. I hope you gave the seller an F rating and a full description of what happened. I learned a long time ago that some people just shouldn't be around guns. About 25 years ago I had a coworker who wanted to see a Walther PP that I have. I brought it to work and had it in the trunk of my car. We went out to the car and I popped the trunk. He reached right in, grabbed the pistol and pulled the trigger. He did this all in such a quick motion that I didn't even have a chance to say anything. Fortunately, I was smart enough to not have it loaded, but it was certainly a lesson in assuming competence. Ever since, I don't.
