One of my shooting buddy's just got a new 45 Colt/45acp RedHawk. It had one chamber that it would not ratchet around on. Locked Up the gun. He got a replacement, and it had the same issue. Note: The dealer got the replacement before sending the first one back, so same problem with 2 different revolvers.
If Old Number Three is not perfect, he has already asked about trying out my S&W 625.
You get a Lemon now and again, but it seems to be happening more frequently on newer production revolvers.

UPDATE: He is now the owner of a JM625 Smith & Wesson. He used it in the last ICORE Revolver Match, and it worked just fine.
