The only others I can think of is Remington and Rock Island armory. I believe the Rems are rebadged, restyled Para's. I know someone who owns a RIA double stack in 45acp. Lots of rounds fired with no problems. The Remington doubles seem to get very favorable reviews.
I'll be looking for a hi-cap 9mm for competition soon. I'm really liking the CZ shadow 2, but I really like 1911's also.
I know, first world problem.
