Thank you for the reply sure the indoor lighting had a lot to do with it. 

Hey guys great sight and have loved reading for hours. 

I have a question for y'all.  I just bought a G20 and was shooting this evening at an indoor range. I shot 100 rounds of Sig fmj and some Hornady 180xtp and a few other odds and ends from when I had a 10mm a few years ago.  Question is do you guys get major muzzle flash for the Hornady ammo?   I didn't notice it with any other ammo shot but with the Hornady it was a major fireball that I could see when fired?  Thanks for any help.
