I just changed out my factory spring in my 96 Brigadier Inox for the D Spring. That is probably the cheapest, best upgrade on the full size berettas you can make. $6.50 to Dave Olhasso. It arrived 4 days after I ordered it. I would recommend him for any new parts you would like to buy for your Beretta http://www.olhasso.com/beretta/index.htm. The trigger pull feels great during dry fire. I will have to get out a shoot this week to get used to it. I take my CHL class on Saturday.
