Gots to be a 1911. Sorry.

However a SA/DA like the 220 fits best in IPSC Production, cept for the shooting a 45 part. Most are shooting 9s cause they kick less and are a lot cheaper to shoot.

I had a 220 in 38 Super/9x19 and used it in IDPA for a while. Fun little gun. Accurate as they come. Ernie Langdon won the IDPA CDP Division Nationals with a 220 in 03 or 04. CDP is mainly a 1911 division, he turned more than a few heads...
