I had one of the very 1st G36's released to the public when I lived in GA. I had it for about 3 years and loved it. The grip was good, it shot great, and was super reliable. I would buy another.
I had one for a number of years, zero problems and fed everything I put into it. The only bitch I have for the 36 is the afterthought magazine extension that was added to fill the grip length. Why in the world didn't they just make the mold form just a little longer so it would look like all the other normal frames?
I have one and really like it. Eats everything, even OLD junk ammo I found. Easy to shoot. Only draw back is 6 rounds. I always carry two extra magazines.
