Is the front sight on my 342PD easily removed, make that easily reinstalled? It seems to have a tiny drift pin. Could I install a Hi Viz ramp or better still an Ashley front sight? The last time I played with a pin like this I was sorry.
Contact the companies who make the sights you are interested in. I know that P-T IWI makes a front blade replacement for the 342, but not about the companies you mention.
