Im new to the gun market and Im hoping for a few suggestions for a gun which meets my needs. Im an extreme cross country runner and at times find my trails taking me into swamps, through creeks, mud, etc. I live in the SouthEast so water moccasins, rattlers, and wild pigs are pretty common - seen em all on trail over the years. I guess Im finally getting old enough that my youth induced invoulnerability if fading so... its time for a bit of something to help out on trail. Im not too worried about trying to drop a pig but having a good snake gun and something that will at least make a little noise and give dogs/pigs/anything else something to think about besides bothering me. The main two things Im looking for are weight and durability. Since Im running less wieght is obviously better. Since Im running in less than ideal areas I want to know that if I swim across a creek and get sand or mud or whatever in the holster and later I need to pull the trigger Im not going to have to worry about the round firing. Also I dont want to spend $800 for a pistol. Im think more like $200 - $400 most likely but for the right gun I might reconsider. So what suggestions would the community experts have for me?
