Dear well intentioned bystander

Dear well intentioned bystander;

Would you have approached a man, who hadn't been shooting next to you , and critiqued his grip?  Would you have told him that his firearm was jumping too much for a 9mm? 

Are you a credentialed instructor?  Did you think it was ok to talk to me that way based on gender?  Do you have any idea what my experience level might be? 

FYI, I know my grip, I have very painful tendonitis and try not to shoot more than 100 rds, because the recoil does show a little more after about 80 rds,

Let mw save you some  time.  If I want your advice. I'll ask.  However, I'm more likely to consult an experienced instructor.

Couple outliers, but not too horrible, 20 feet, speed...  Yes, I was walking a little, my arms hurt, but still, that pattern is well within center chest range.

So, well intentioned bystander.  Thanks but no thanks.
