First off when I joined this forum and soon after I did I mentioned what I was doing with a 2240 however you guys don't recognize the H---c as being safe or something but I've found out it is, enough said about that here is a pic showing a couple mods I did with my Prod after watching results people were getting from different tranfer port I.D.'s and I also added a Discovery hammer spring for a stronger hammer spring. I managed to get this pistol from a 15fpe up to 21fpe very easily.

Beautiful gun and some great fps numbers. Prods are an amazing gun IMHO. You have done well with yours.
Nice tune on the Prod.
