I have both a 4.25 and a 5” Prodigy. The slide to frame fit and barrel/lug fit is as good as any 1911/2011 I’ve had including an STI Matauder and a Les Baer Premier. The trigger on the 5” was fine. The 4.25 trigger needed a little TLC. Both run great with any ammo, even my Bunny fart IDPA handloads. Just a little positive for a change.
