I'm an old man (60 with tri focals) but I am going to enter my first GSSF indoor match Saturday. I have been shooting fairly regular. I don't have a lot of money for bullets, although I do reload. It makes it cheaper but still, I need to pay bills first. Anyway, I have been shooting my Glock 19 4th gen and I really like the gun. I will be shooting it stock with the factory sights. My question is consistancy with the Glock and it's grip. I have days where I can drill out a 2-3" hole at 10 to 15 yards (not real often) and days where I am all over a 8"X11" sheet of paper. I can then take out my M&P on the same bad day shooting the Glock and I always shoot the M&P better. Could it be I should stick with the M&P, which I can't use in GSSF, tough it out with the G19 and hope for the best Saturday, drink less coffee ? I have always had a love hate relationship with my Glocks, mostly because of inconsistancy. I am even thinking of selling my new G17 because I am worse with that even. Practice has helped a lot along with dry fire but still...I feel I should shoot the G19 well ALL the time or at least 90-95% of the time. If anyone has a few clues I am all ears....maybe eyes for on here !
