I am looking to change out my trigger on my S&W M&P 9c, the gas block on my AR-15 and eventually the trigger on my AR as well. To do these I'll need to knock out roll pins and regular solid pins (not sure of their technical name). I'm wondering, can I get a set of one type of punches and have it work for both types of pins? Do I need roll pin punches for roll pins? And if so, would Roll pin punches work for regular solid pins? Thanks in advance for your input.
