Does anyone have experience with this trigger?It's single stage and pretty heavy.The gun is without a safety, so I'm a little leery about lightening it without any knowledge or experience with this model.It is possible that my newly acquired example is low mileage, so if these triggers are known to lighten up with use, let me know to wait for it.ALSO, where might original front and rear sights be located?I'll appreciate any insight the members can provide.Thanks to everyone who makes this sight the indispensable resource that it is!A very classy group of knowledgeable and helpful folk.
