Whenever I'm down in Grand Junction, CO, I always stop in at the Sportsman's Warehouse to see what new stuff they might have. A couple weeks ago, while at SW, I saw a real nice Yaqui Slide holster for an H&K USPc .40.
I was wearing my EDC (H&K P2000) and thought that the holster might fit it.
With the holster, I went over to the clerk & and said:
"Say, I'm carrying a pistol that I think this holster might fit. Would you have any problem with me checking that right now. If you don't want me to, I'll understand."
"No problem." the clerk said.
We went down to the end of the counter, where there were no customers; I removed the mag, cleared the round in the chamber & handed it to him at slide lock. He examined it and handed it back to me. I then closed the slide and put in in the Yaqui. it fit nicely.
I reholstered my now empty pistol, paid for the new holster at the front register and left. I went to me car where I reloaded my pistol. I don't think anyone noticed the entire transaction.
