I still do not agree with not using a mosfet, it still reduces trigger contacts wearing down and if that is not the problem then it is still a big reduction in your trigger response. I think you can get a just as good trigger response with a mosfet and 7.4V when compared with a 11.1V without one. Also you can make your own mosfet from 5-8 euro using a 3034 mosfet which is used by a lot of companies to make their basic mosfets. Probably another benefit of a mosfet is that you will get some more shots out of a battery.
