A buddy of mine got one when they first came out....The only issue he had was with the magazines...Springfield Armory was good about it and replaced the magazines and she runs fine now....
Had one of the GI models. Sent back to Springfield custom shop for Novak cut rear sight, dovetail front, ed brown beavertail, combat hammer, trigger work, ed brown fitted barrel bushing and finished in Black T. Sold it a year later. Gun would not go into full battery after each shot until there were less than 10 rounds left in the mag. Just had to tap the bottom of the mag and it'd go back into battery.
