I purchased a TRP back in January at a stoopid low price (thanks Gunjoker) and I saved enough money on it that I've been swapping out the parts I don't like (or trust) for what I prefer. A few range sessions had me rather happy with the function of this pistol, but I just could not warm up to the fake Novak sights. The rear sight in particular was too tall IMHO and the rear notch was too tight. They were fine for precision, but I struggled to find the front blade in anything less than bright sunlight. For background, I'm 53 and I wear contacts to fix my nearsightedness. Aging eyes, and my prescription combine to make sight selection tricky. I really like the 10-8 rear sight with the .140 U-notch. I have those on a couple of 1911s. Today I mounted the Heinie Ledge rear sight on the TRP. (keeping the OEM front tritium sight) https://www.heinie.com/1911-500x65-ledge/ The rear notch is wide. .156 is the biggest I've tried, but the front sight blade is nice and sharp and easy to find. Even walking around inside my house, pointing the empty pistol into corners and unlit rooms the front blade is still well defined. I have not put rounds downrange with this rear sight yet, but I'm really happy with the vast improvement in front sight clarity and speed of acquisition. (They also mount in an innovative way but that is of secondary importance) TLDR: If you are experiencing difficulty finding that front sight, try a wider rear notch.
