I have a CW 45 and it shoots anything I put in it, reloads or factory it is very accurate and dependable, where do I get a fiber optic sight for it and will it stay in after installation, I had a colt combat commander awhile back and someone put a taller sight on it and it would come out after a few rounds were shot in it, bought a staking tool and installed another sight and it came out also, finally had a machinest cut a dove tail in it and solved the problem but it was not a cheap fix, kind of burned me out on staked frount sights, but I might try one again on my Kahr, thanks Don A.
