I never even used the original stock on the 995, it just looked "cheap" and not safe. I'm sure it's safe, but I just went ahead and got the ATI stock instead.
Upon closer inspection the ATI stock is WAY thicker and has more alot more strength than the original and, like stated before, it's mostly 1 piece and can be modified easier. When I took the original off and put the 2 pieces back together I found I could actually flex the whole stock almost 180 degrees! On the other hand the ATI stock barely flexes at all, if any. The ATI material and molding process is superior to the original.
The only thing I do not like about the ATI stock is how wide the grip is. It's hard to get my right thumb against the clip release button sometimes, I usually have to use my left hand, and I have average finger length. I think they did this to accomadate left handed shooters, not sure.
I would honestly suggest this stock as the 1st upgrade for this firearm, then a compensator.
