I bought one of the first ones from Plainfield with the express intention of breaking it. I couldn't. We really, really tried to break it. Kept getting better in fact.
I have a railed Taurus with Surefire X300 at my bedside.
I intensely dislike the lock on the hammer, but that can be fixed.
My new springfield does the same thing.....I took mine out to the range for the first time the other day. Put 350 rounds of assorted cheap stuff through it. Shoots great, not a single problem with ball ammo. I shot a box of gold-dots through it after that and when the mag is filled (wilson's and taurus mags) to 8 rounds the first round out of the mag nose-dived everytime. Every round after that fed just fine. I dont know much about 1911's but I think it may just need a lighter recoil spring put in, or I need to find some different ammo. Otherwise, for now I'm just keeping the 8th round in the mag a ball round and the rest are JHP's.
