Hello. After thinking about it and taking all of your advice I have decided to purchase a Ruger MKIII 22/45 .22 handgun. My last question about this issue is that it comes in 2 types of barrels: stainless steel, and the normal factory black barrel (material unknown). The stainless steel costs more but looks cooler. Is there any other advantages to the stainless steel barrel other than looks? Which should I purchase? Thanx.
