Thanks for all the replies guys!
I already reload for my 308 so I already went ahead and got a 9mm die set along with some primers (walked into a turners with a 1k box left... lucky me!)
I will definitely begin to read the the rules for the different competitions but my aim at getting this gun was to put a compensator on. I have ALWAYS wanted to own a compensated pistol after i shot one at the range one time. So this gun will most likely be for open.
I have already did a little research on how to get a comp on this pistol and it doesnt sound easy. I basically gathered that I will need a 6" barrel (probably will have to cut and recrown), long guide rod, and the compensator itself with smithing work. Anything I missed or is inaccurate?
Again, thanks for the warm welcome!
Edit: I am in Southern California, Orange County to be exact. Anyone know any reputable smiths that will work with the witness match or 1911's? (im on a spending spree and am already contemplating getting this gun. Most likely a double stack and keep it mainly stock until I decide what I will use it for)
