One stop shop for Beretta and Sig modifications.
www.langdontactical.comErnest did up my Beretta 92g Elite II last year. With the proper ammo it'll do under an inch at 50 feet all day long. It can outshoot me any day.
I have him install a Bar-sto 4.7" gunsmith fit barrel into it. He put in a new trigger with an over-travel stop. Smoothed the DA to 8 lbs. and the SA to 4 lbs. (I carry this gun so it's as low as I'll go.) He did up a bevel job on it and refinished the frame in black Teflon-S.
He put on Novak night sights, and put a Spur-less hammer on it.
For a race gun, you could put a longer ported barrel in it, go lower with the trigger pull weight, perhaps a fiber optic front sight.
Some offer to install the bushing like Jarvis, those look okay for race guns. I've seen frame to slide tightening done by Handgunner. Unknown of the extent of its effect (on accuracy AND reliability.)
You could also buy a Beretta 'Stock,' or one of the other long slide models.
I'm experienced no failures with the weapon since it's return and I trust it with my life every day.
