I put it on a GSG 1911. It's not exactly a Novak cut, so I had to do a little fitting. Fits like glove now, easy install.

Install was easy and mount appears very sturdy. Red dot is low on gun and looks appropriate . Would definitely recommend EGW

I ordered it not realizing I needed the mount for my 507k. There is a size difference between the 507 c and 507k. Why Holosun does this I don’t know. EGW should specify in the description that the 507c does not fit the 507k and vice versa. If it does I missed it and that is on me. Shipping and Customer service at EGW is great though!

Fit well after some light filing with a multi-tool. Fits the 507c not the 407c by Holosun. The 407c is a bit wider. Thanks!

Operating as designed. Fit was great. No additional work needed. Press out factory rear sight and reinstall new one that screws down the mount. Easy enough for anyone to do.

Did not easily push in with a sight pusher… I had a gunsmith fit it to the Novak cut on my colt defender .45 acp.

I wasn't sure if EGW's mounts would fit the Springfield Armory Emissary so I emailed EGW and asked. I was pointed to the mounts that would be compatible. I selected one and while placing the order was given the opportunity to purchase a red dot and receive $20 off the order with free shipping. That was a no brainer as the same red dot on Amazon was the same price. The mount and red dot are now on the Emissary and I could not be happier. Great customer support, good pricing, and fast shipping

The mount was for a Colt 1911 Competition with a Novak adjustable rear sight. The problem was that the mount dovetail was too big to fit into the pistol dovetail. It was necessary to file down the mount dovetail to get it into the pistol. However, once it was finally in, it was fine.
