Well, I have been to the range 4 times since purchasing my 23, my first glock/gun purchase, and I am really getting a feel for it. After 300 rounds of 180 grain I have had two stovepipes? though. I think that's what its called when the empty brass doesn't completely eject and it gets stuck when the slide comes back forward. Ammo was Winchester white box which I haven't heard great things about, so maybe that is why. My first two range trips did not go so great. At least as far as my accuracy is concerned. I found some great information on GT though and determined that as a lot of new shooters do I was overgripping causing me to shoot low left. My third time out went great as my accuracy improved greatly. Also after shooting the .40's well I tried the LoneWolf 40-9 conversion barrel for the first time. I was able to put over a 100 rounds through it without a problem. I did not change out any other parts, just the barrel and 9mm mags. I do experience a little BTF (I'm learning some of the acronyms) shooting 9's but no issues shooting .40's and most of the time the 9's just hit me in the chest. I had been wanting to take the concealed handgun license class but was previously concerned about my marksmanship. But after that last range trip I felt very confident and signed up for the class. Not that its that difficult but knowing how I started out shooting a couple of months ago I was very pleased to shoot a perfect score and really only had a few rounds outside of the "9" oval. Three others had perfect scores but two of them had quite a few "8's" so I would say only one person outshot me and it was very close. There were nine shooters in the class. Next up either a Glock 17 or 34 in FDE and will likely get a .357 barrel for my 23 as well. I don't post much but I visit almost every day as I usually learn something. Good shootin everybody!
