Got a .40S&W widebody 1911 that I plan to use in both IPSC Limited and IDPA ESP. It has a bull barrel but I have another top end in 38 Super with a bushing type barrel under development so I can have a 2-in-1 toy gun. I'd like to put in a drop-in magwell for IPSC games and take it out for IDPA matches. Which drop-in magwell can I use that would still allow the use of the standard Para magazines?
