pareho kami ni saki may 2in1 1911 project. 2 slides fitted to 1 frame. mine is in 2 calibers though, .45 and 9mm. the existing gun is .45 while the 2nd upper assembly will be in 9mm. do you guys foresee a problem? the initial difficulty i anticipate will be because of the difference in the barrels, the existing gun uses a non-ramped barrel, the 9mm barrels i see available are all ramped. the cheaper move seems to be to "unramp" the 9mm barrel. (ramped .45 barrels being quite expensive.) will that work? do you think there will be problems? will 9mm feed reliably on the "unramped" barrel? any thoughts or suggestions will be very much appreciated. thanks, brothers.
