I regularly shoot both single and double stage triggers so am used to both of them and depending on which firearm I am using. MSR type firearms all come with double stage triggers, which is somewhat of a safety feature, not only on MSR types but all different firearms using a double stage trigger. The double stage allows you to take up the slack and finalize your sight alignment, do the breathing before you initiate the final trigger press. Trigger pulls on semi automatic firearms should be set to at least 4.5 pounds for safety reasons. It is too easy to accidentally press the trigger during the recoil, especially if you are wearing gloves.
As for single stage triggers my other rifles all are single stage. The major downfall of the single stage trigger is that it is too easy for the gun to inadvertently discharge, especially if the trigger pull is set too light and even more so when wearing gloves. I have my single stage triggers set to 2.5 to 3.0 pounds. While this does not require a significant amount of pressure during a trigger press to fire the firearm it does give some margin of error while in the process of aligning the sights and the time you actually want the firearm to discharge.
The name of the game is SAFETY!! a trigger of either type set too light is an invitation for an unintentional discharge of the firearm. For those of you who have your trigger set to ounces instead of pounds and maybe ounces how would it feel to have a buck or elk of a lifetime or maybe even a new record and as you are setting up for the shot inadvertently cause the firearm to discharge before you were ready. What would you be thinking as you watch the trophy run off in the distance. I know people who espoused to the light trigger pulls that this has happened to. Simply stated, "Be safe or be sorry,"
