I'm getting ready for the match in topton pa next month. So I've been working on my dry firing drills with a new G17 I just got about 3 months ago. I had a G33 which I traded in for the G17. (Cheaper ammo = more practice). One of the things I noticed in getting my 17 was that I have a much more difficult time keeping the front site steady in dryfire practice than I did with the 33. The shot break on the 33 was really smooth. It was like BUTTA. As a side note, I bought the 33 about a 1.5 years ago and it was used when I bought it. Is it possible that the 17 just needs a break in period to smooth out the trigger pull so I can keep that front site steady? (I did polish the trigger parts when I first got it). What are some of your experiences with older used glocks vs. brand new ones?
