After sending my new 30SF back to Glock for the second time because of FTRTB issues, Glock sent me a new pistol. I picked it up today at my local FFL and put 50 rounds down range. A few hiccups in the first 10 rounds, but everything went smoothly after that. Seems the new pistol is a shooter, and a keeper. Also want to say that Glock customer service (John, in technical services) has been fantastic. The return trips of my old gun cost me nothing, and they sent me a brand spanking new replacement (test fired on March 4) that works as it should.
