Does the Pistol have a warranty? MAybe send it back to the company for repairs?
I would keep shooting it until you have 500 rounds through it, then take it to a smith if there are still problems.
Can you return the pistol to the dealer (doubtful but worth a try if you aare unhappy with it) If so, get a springfield milspec 1911- they can be had for about the same price, have a lifetime waranty, and tend to work really reliably.
