i think you got enough responses pal but just to add my 2 cents. Have a feel of both and choose what feels best as both guns will out shoot the shooter
personally the hw 100 was a bit heavy for me but then im not exactly a big lad lol but as stated above its an absolute dream to shoot the s410 was alot more comfortable in my arms and also as sweet to shoot!!!! so my advice is simple GET BOTH one in 2.2 one in 1.77 hahahahaha good luck with the decision pal let us know what you get atb craig HAPPY HUNTING!!!
