Preamble - So I bought a 935 last month and besides it being a little heavy I love it. Bought it mainly for waterfowl but want to take my 20 year old daughter for Turkey in the spring. Was given a brand new 930 Mesa Tactical Urbino pistol grip stock that has a shorter length of pull and its own buffer spring assembly. Question - With the stock and spring being designed for the 930 any idea if there would be any complications in operation on a 935? Mesa Tactical says they do not know. I would assume it would be fine with 3” but not sure about 3 1/2”. Thanks in advance.
