My first post here as a new member. I picked up my first Glock 23 Gen 4 in 40 S&W this past Friday night. I took it to the range Sunday afternoon. I shot 50 rounds of Winchester 180gr FMJ target loads, these are factory loads from a local store. I put a target at 25 yards. I would shoot 12 rounds then take a break. I have no clue if that is proper break in for a pistol or not, I mainly shoot black powder rifles and muskets. Every 12 shot group would have a min of 9 holes (I'm sure I caused the fliers). One 12 shot group had all shoots in the scoring rings. Needless to say, I was very much impressed. Thanks Glock, I know another one will be in my near future! I am looking for thoughts on good factory ammo that would be good to use and good starter reload loads since I will do alot of reloading. Thanks to you all, any info would be helpful and hope for a long and happy relationship with my 23. I forgot to mention, I live in N. Illinois Wanna kill these ads? We can help!
