I put a Wilson barrel, bushing and links in my .45 Colt 1911 - originally a .38Super.

I shot the Super for a while, even made my own brass out of .38SPL and .357 Mag. - worked just fine, but I really wanted a .45, so I changed it. Really freaked out the local constable when I changed the registration over - actually that I was able to do it so easily.

I ported the barrel (3 holes each side) and slide (slot), and after that could clean the 10 yard falling plate (6) rack in 2 seconds including the draw. An RCMP buddy who used to shoot with us at the jail range, timed it.

My best was with the 300gr. at 550 to 600fps - LOL - I'd be on the third plate before the 1st fell over. What a blast.

A 9mm could not tip a plate over unless it hit within 1/2" of the top edge. The 300's bowled them over with a hit anywhere. Even a factory .38SPL would knock them over with a center hit with 158gr.RN factory, from my 4" Colt. Pretty funny, actually. Guy with the P35 didn't think so.
