Nice gun! The rear sight looks quite sturdy. What brand and model?
It is just a cheap Colt knockoff.
A Les Baer Premier 2.
One of the 1.5" guns
I had some mods done to better suit me. The huge boat paddle ambi safeties were removed and an old style Colt single sided thumb safety was installed. An S&A magwell was added, along with a fiber optic front sight.
