    Exactly what I was looking for, at a great price. All of the parts were present, easily assembled, and functions as expected. The finish was also very nice. All in all, this is a good deal!

    Surprising quality at a great price!

    Wanted a flat mainspring housing for a lower end Tisas 1911 I have. Not wanting to spend a lot I found this one. For about the cost of a colt plastic housing you get a good aluminum one complete with spring, both ends and the capture pin. Looks great, sharp and deep checkering. Nice finish. No fitting needed for mine. Slid in with a bit of drag as one should, and lined up perfectly. I’ll be buying more of these. Great part, price, and shipping was fast. Can’t beat it!

  • Excellent

    I wanted to stay with aluminum easy to fit lighter weight, never have worry about rust, more than strong enough for mainspring housing. A couple of light strokes with 1000 grit ultra fine sandpaper on the side rails of the main spring housing and it fits right in the frame, perfect fit!

  • Great item

    Great product...might require some slight fitting...Mine did..but, nothing is truly a drop in part when it comes to a 1911...looks great on my build..

  • Great Quality!

    This housing was so light, at first, I thought it was plastic! It isn't. It is aluminum, nicely finished with great checkering on it. Easy to put together and install. Did exactly what I wanted it to do. Looks great, very comfortable. It was an excellent choice, glad I bought it. Good ebayer, too. Shipped fast and actually delivered a day early.

  • Great choice for a low maintenance approach...

    I bought one of these for my favorite Kimber, and liked it so much I bought another for an Auto Ordnance 1911A1. It works well, fits perfectly, keeps the weight down, and it makes up a good bit of surface area for which I no longer have to worry about rust. If you're not a 1911 purist, or are just looking for a solid replacement MSH...look no further.
