I haven't heard of any problems with that particular brand.....but it's not suprising. It seems like everybody and his brother are making copies/clones of the M1911 nowadays.
Some like Kimber/Wilson/Springfield are quality guns, but some are cheaply made junk.
It's not enough to copy the Colt/Browning design. The execution (materials, machining, fit, and finish) have to match the original to get the reliability, durability, and function of this fine firearm.
The moral? You get what you pay for!
