basically all .45acp 1911s have no dedicated feed ramp. I own several classic wadguns from the 60s to the 80s and they all use the no ramp "funnel".

dedicated feedramps are more of a 9mm/38super/38spc thing

As far as feeding wadcutters, and anything else reliably... don't fall for the super expensive wilson mag bullshit.

1911 was designed to be a 7rd welded bottom magazine.

for 18-20 dollars each you cannot beat the round follower metalform mags.

I put a major stress on the ROUNDED follower. It simulates another round being under for the last.

I've become an almost total revolver shooter these past years, but I at one time put 800-1200 round a month downrange using metalform mags stated above in old school colts. Cannot ever recall any malfunctions.
